I used to spend the vast amount of my time debugging.

Fast forward a few years - Experience, good programming habits, and the gratuitous use of assertions. Now I spend a negligible amount of time debugging, and it never ceases to amaze me how frequently things just work the first time.

Edit: I guess I want to say that there is one, and only one, bottom line: the relentless, ruthless pursuit of quality. It takes time to develop the good habits and watch for the pitfalls, but once you're there you develop your software products in a quarter as much time, with one tenth the stress, and everyone on your team feels proud of themselves and each other. Then with your free time you can focus on what's really important - your business and your life

Neither, I spend more time writing or thinking about tests. When I was earlier in my career I used to insert debug comments, run code, look at output to figure out what was going on. Now, I try to write my tests that will eliminate the need to debug. If I'm trying to fix a bug, the first thing I do is write tests for what should happen if the tests don't already exist and work backwards from there. If you get in a good habit of this, it just becomes natural and with today's toolchains you can re-run tests with a watcher to achieve a real time feedback loop, which is better than a debugger IMO. The plus side is going forward you always know that the code works vs just seeing it work that one time. As your application grows, something may change what the value of the debug statement output and you'll never catch it, but your test will. /old man rant

From The Mythical Man-Month by Fred Brooks:

 """
No parts of the schedule are so thoroughly affected by sequential constraints as component debugging and system test. Furthermore, the time required depends on the number and subtlety of the errors encountered. Theoretically this number should be zero. Because of optimism, we usually expect the number of bugs to be smaller than it turns out to be. Therefore testing is usually the most mis-scheduled part of programming. For some years I have been successfully using the following rule of thumb for scheduling a software task:

 1/3 planning 1/6 coding 1/4 component test and early system test 1/4 system test, all components in hand. This differs from conventional scheduling in several important ways:
1. The fraction devoted to planning is larger than normal. Even so, it is barely enough to produce a detailed and solid specification, and not enough to include research or exploration of totally new techniques.

2. The half of the schedule devoted to debugging of completed code is much larger than normal.

3. The part that is easy to estimate, i.e., coding, is given only one-sixth of the schedule.

It seems a lot of people here are talking about debugging in the context of automated tests and manually stepping through debugger loops.

For me debugging usually means "figuring out why we had an outage." This means looking at: 1) application logs, 2) server metrics, and 3) source code associated with the failed applications.

I recently had to ssh and run ngrep on 8(!) servers to see how groups of messages passed around and then look at timestamps to correlate what happened. It was very tedious. This could have been saved by better debug logging; we could have switched that on for 2 minutes, run the tests, and and the looked at everything in Logstash.

When this happens, I end up spending a ton of time tracking down errors. On a bad week, this can be half my time.

So to me, debugging is as much thinking about how you'll have to solve errors in the future and planning for it as it is writing unit tests and tweaking code.

Debugging.

I've sunk a lot of time into trying to change this. Among other changes, I've:

- Improved crash dump collection, to spend less time reproducing bugs and be more thorough in addressing them.

- Improved code debuggability - for example, writing scripts to inject call stack information into actionscript and java via disassembly, which I can then display on assert, especially on platforms where I have unreliable or incomplete debuggers.

- Learn and use defensive coding techniques to make bugs fewer in number, shallow, and caught more quickly and with more context.

- Write thorough tests to catch said bugs before I even run my main application, and more edge cases to input

- Learned more tools to catch bugs I might not even know exist - valgrind, address sanitizer, static analyzers, fuzz testers, ...

I spend much less time debugging my own code now. If I'm lucky, I'll work on projects where I don't have to debug my coworker's code all that much either. That still leaves debugging 3rd party libraries and tools - which I may lack the source to entirely - that I suddenly have more free time to really properly investigate and get to the root cause of.

Definitely not debugging.

I am working on an existing distributed system with many moving pieces, which is rather prone to outages. This is fintech, so outages mean a lot of money for a lot of people. So my job involves overhauling the existing system, as I upgrade bits of the system slowly: A full rewrite at once would be madness, but I suspect nothing in the current system will remain in two years.

The biggest time sinks are stress testing any of the newer pieces that I try to bring in, followed by incident remediation. There's an incident that requires a human hand to fix it every couple of weeks or so, and I end up spending about three days each time writing better error handling code, adding observability and alerts, and if something is really recurring, writing automation to make the problem fix itself.

This is a fact of life in any distributed system that was written fast: People are start happy because it works most of the time, but as you want the 4th and 5th nine, you need people hardening the system. This is something that is very hard to do as you build anyway: While unit tests are good, there are entire layers of behavior nobody will be able to spec properly by looking one piece at a time, so stress testing, gamedays and such are the only ways to make sure not that the system works to a spec, but that we can even come up with a spec that behaves the way we want in practice.

There's value in evaluating scenarios in your head, but I've also seen what happens when mathematicians use that as their only weapon in a distributed system: Months are spent making sure the system is correct, but then lots of effort is spent on scenarios that are more theoretical than practical, and other scenarios are ignored, even though they occur a lot in practice.

In this respect, it's not very different from entrepreneurship: Getting an MVP out the door and doing things by hand instead of using automation is going to beat spending a lot of time making a product without having any idea of what the market really wants.

Preface: I work with C/C++ the majority of my time. C#, F#, and PowerShell are the bulk of my remaining professional time. Go & OCaml/F# at home.

When I started, the bulk of my time was debugging my own code. I am gifted with the ability to write vast swathes of code in a short amount of time and when I was younger, it was vast swathes of shit code.

A little later into my career years 3.5-5, I spent more time coding and less time debugging. I designed my code better, used better patterns, and generally was just an all around better engineer.

I've come into the third stage of my career now where I spend a good portion of my time debugging junior engineers' code in a complex system I work on. In particular, my focus is usually in reliability and performance. I don't tend to debug the junior engineer one-off issues but rather the subtle regressions introduced by seemingly harmless changes.

In this third stage, I still write a lot of code, but much more of it is investigative and refinement over existing ideas with occasional injection of something wholly new.

A bunch of time planning the change and reading through the current version of the code, so that I can add things without breaking everything else (and/or understand the current behavior and the desired behavior, so I can repair the bug). About half as long actually writing new code, and then debugging iterations until the tests work again. Some time writing new tests for the feature. Some time fixing integration issues (occasionally). A fair amount of time dealing with customer escalations (usually tiny edge cases really messing stuff up at a customer's site).

So, they're all bugs, and in a sense, all coding is debugging. New-feature, regression, existing (from previous release), and escalation bugs. They're all basically the same thing: Identify the deficit, write a fix (includes what you might have meant by "debugging"), write tests to cover the changed behavior, check it in, deploy/release.

Well, it's a fairly even split of both. But a lot of time is spent fixing projects that started as something really simple and immediately ballooned into some sort of bloated megaproject that ended up with no cohesive plan in regards to how anything would be tested.

Bonus points if the project started as one thing and pivoted to something completely different midway through development, and about 50% of the code is completely unused.

Lately, it's mostly debugging. I rarely find debugging difficult (tedious at worst), and I like fixing real problems (vs building a new feature or component I don't see the reason behind) so that suits me just fine.

Honestly, I'm probably better at it than building new features anyway.

Implementation (existing code) - 30%

 Maintaining - if this means soft feature creep, then 10% Maintaining - if this means bug fixes and other things, put in implementation, 5%
Creating nice PPTs and control documents about stuff - 30%

 I genuinely like this New functionality 20%, including sitting with users for new functionality requests, seeing their workflow
My main job. Having whittled this down to 20% of my day, I need to start ramping it up again. It is nice to have 10% time, and I loved 50% time, but 80& time may get discovered (though all time is dedicated to the company)

Other stuff. Like filling in timesheets, which assume hours can accurately be attributed to discrete tasks for discrete people any and all of the time.*

* Just set goals for staff. Do staff achieve their goals? If so, why timesheet? Or just timesheet roughly, my hour-by-hour 7 day per week sheet is a pain.

I think it will really depend on the role.

- One project is in active development, and I probably spend about 70-80% of keyboard time coding with 20% debugging.

- A separate project is in maintenance mode, and obviously most of my time on it is debugging as bugs come in. So probably opposite, 70-80% debugging there.

- Sometimes feature extension requests come in, in which case it's probably closer to 50/50 on that project.

If you consider that the life of a software product is 5 years, it would typically take the first 3 months to build v1. So coding vs debugging would pretty much be in the same proportion. 3:60 in this case.

I'm not sure there's much than can be concluded by someone's ratio. I definitely wouldn't assume that someone who spent more time debugging was a "worse" programmer.

There are certainly practices that reduce the amount of debugging, but it's all relative. Personally, the question for me is nearer something like;

debugging. because coding is the easiest part.when I am asked to build any feature. I take some time thinking on what and how should I do (around 10%-20% of my time). Once I feel like I have a good idea I continue to code (But sometime when I start to code I spend more time on thinking on designing code, like best practises etc.) so I think like 30%-40% of my time go to coding and thinking about best code practises. But then comes the part where I really struggle DEBUGGING. Rest of my time go in debugging stuff,

But I am not sure how can I improve myself. I am not sure whether anyone faced this but I feel like the starters really feel the same way.

All fun lies in debugging I sometime love it. I find funny bugs in my code. But it is so time consuming and I really want to reduce that. Not sure how. Any help will be thankful.

Roughly equal, probably debugging takes more time (or at least it feels that way!).

Usually can get through a chunk of code no problems but when that 1 inevitable bug arises it will take up a lot of time through trial and error, stack overflow and just generally googling to find a solution.

I spent more time in the planning stages, followed by debugging, followed by writing code.

I work in an environment where tests are unheard of. Most of the Javascript written is erring towards the "simple" side with many edge cases as it is all written for front-end web development. Things like calculating the size of the header, adding/removing classes based on certain user actions, managing Google Maps or having logic for complex forms.

Most things are several small (<10 line) functions.

The most complex thing I've built is a pre-qualification form. Thank god for moment.js, because I never thought it would be so difficult to calculate if someone is between the ages of 40 and 82 (or will be 40 by October 15th of next year).

Of all the answers here that provide stats, I wonder what percentage of those have actually measured the time versus just giving numbers that 'feel about right'. If there is one thing I've learned about stats it is that 96.60% of people's gut feel is usually wrong ;-)

That said, about the question asked. I can attest to the fact that in general thinking and writing good tests greatly reduces time spent debugging. Also, adding judicious and useful logging for the critical / edge cases helps a whole lot.

In terms of the complexity of the app, I'd say to start looking into the kinds of technologies you'll need to fulfil the requirements. Sounds like you will need a server somewhere with an API, and of course the app itself on whatever platform is appropriate. I have not done much mobile app development myself, but I would not underestimate the impact on the project of, for example, learning how to develop an Android app. Each ecosystem has its own vocabulary and conventions you will have to understand in order to develop the app well.

That, of course, is not to say that you can't get something out in two or three months that is functional, if rough around the edges (at least in terms of the code).

If you're really worried about the possibility of not being able to deliver, I would advise you to pay close attention to the terms of the contract if they offer you the gig -- how much freedom do you have on the project, are you accountable for its success (particularly in a financial sense).

You can recommend that the company bring on another developer, perhaps before you sign stuff. Treat it less as a negotiation with an employer and more like a consultation with a client: you want the app to be successful, and another developer would help to ensure that.

I once turned down an accepted offer because I realized I was not qualified to perform the task. They wanted me to analyze and estimate the time required for a rewrite on technology I was totally unfamiliar with. The greenfield development was extremely attractive to me, but I was able to temper it by coming to terms with the fact that the stress of achieving their goals with my time and skills would be really irresponsible. There are other opportunities. Don't sacrifice your sanity.

Chances are, if they went to a University to get an app developed, they want it cheap. I've been in on more than one meeting where this was suggested.

Just be honest about the whole project. Let them know what they are getting into and set a plan from the start. If they decide to keep adding on requirements or changing things around, let them know how much time it will add onto the project.

You may never get the project done and it may be really complicated, but it will be great experience. I have many projects like these that I worked on after college.

1. You're correct, those requirements aren't trivial. They're also not impossible, it's just a considerable amount of work.

Phone libraries won't magically solve any of your issues.

2. I would attempt to drastically reduce the scope. Emphasize the worst-case development time to your client. The client's reaction to this is often very informative. My best clients react by accepting my concerns and scaling back the requirements to the bare minimum. My worst clients have refused to acknowledge serious issues and insisted on charging ahead without changes to the plan.

3. You avoid being taken advantage of by having a better offer. Since you can't do this immediately, accept that you will be taken advantage of until you can clearly signal your value. Put effort into personal projects and other visible demonstrations.

There's an entire community of video game hackers (smwcentral.net) using a cross-assembler I wrote in 2001 named xkas. I added a few minor patches and by early 2004 I had released the final version, v06.

I never really intended for anyone to use it seriously. I made it for myself, but went ahead and posted it online anyway. It is a 1500-line single-file, nearly-commentless, nearly-spaceless abomination of code with no documentation, and an endless list of critical bugs that every user keeps encountering. They have elaborate workarounds for many of these bugs.

It became a negative feedback loop: "Why do we use xkas? Because everything else is written in xkas", and so now even more code was created and written in xkas. And so even though I've since written a proper assembler that's dozens of times nicer, no one can/will use it.

Lately, people have been writing their own versions (in addition to countless forks) that try to offer backward compatibility with all the crazy parsing errors and (mis)features of xkas, like left-to-right evaluation of math expressions, and the most convoluted macro evaluation system you've ever seen (one user proved it was Turing complete and wrote a Brainfuck parser in it.)

It's surreal. I feel terrible that so many people are stuck with this mess, but even I can't stop it anymore :/

I am the original author of LatexMk[1], a Perl script that runs Latex the correct number of times to ensure all cross-references and such were resolved. It can also run continuously with a previewer and several other goodies.

I wrote it around 1993 to scratch my own itch, adapting it from a little script called Go by David J. Musliner. At the time I was using a literate programming tool that generated Latex from C code. When I moved on from that job a couple of years later, I released a final version two, which documented that I was no longer planning to maintain it. Since then John Collins took up the cause and been doing a wonderful job from what I can tell from occasional ego searches through google and stackexchange.

Two amusing things: 1) It is the only piece of Perl code I have written, ever, and 2) I had reason to use Latex a few years later, and decided I really dislike the sheer complexity of it all. Despite that, it is surely the most enduring and widely used piece of code that I can claim credit to having a hand in.

I have the horrific horror (honour?) of knowing that a lot of my code is still live.

The oldest is the internal system for a record label written in 1997 and I still occasionally get emails asking how such and such works (and I have little idea, it was in PERL).

Through to code that processes video and audio snippets for most of the UK Football League premium content sites. Authored in 2000 (mostly VBScripts that slice, encode, and distribute media files and the metadata).

Parts of btinternet.com still appear to use my horrible CMS... written in 1999... though gladly it's now very few parts and I suspect these are just cached outputs rather than the CMS still being in production.

Most worryingly would be the UK Home Office, and most UK banks and some heavy manufacturing companies that I wrote project management reporting software for over a decade ago, and as they manage 20 year projects I believe that stuff has at least another decade in production. At least all of these systems are not internet connected (then again, they'll never be updated either).

My code isn't terrible clever or pretty, those requirements got dropped a long time ago. But I have learned to make code that is simple to read, easy to maintain and tweak, and that can sprintf debug with the best of them (debug tools of choice have come and gone in the time my code has been live).

I wrote a data recovery POSIX compliant command line app in C in 2003 that runs under OS X, Windows, and linux. It's still selling well, and has been all these years. Over time it's generated millions in revenue as it's been used by several different competing apps, and I have only recompiled it about twice in the last 15 years, each time only making a (very) minor change. It went a good decade without a recompile and continued selling well and being widely used.

The reason I'm happy to say this publicly is because

a) it took years to write, full time. Data recovery is a hell of a lot more complex then I'd ever imagined.

b) data recovery is no longer possible on SSD's (if they have TRIM enabled, as they do in all major OS's) so it's a declining market. Anyone would be nuts to be trying to enter it at this point.

In 1999, I created the r_waterripple variable in Quakeforge which has propagated to most subsequent Quake ports. The implementation may or may not vary, but all projects seem to have carried the variable name. I also contributed pk3 unpacking and resurrected the Solaris port, either of which may have code circulating.

Also between 1999 and 2001, I was involved in the LiViD project where I worked on a port to PowerPC. I don't recall any patches actually landing into LiViD because it turned out that the bug was in GCC itself, a bug I was told must have existed since the mid-eighties. I didn't directly write the GCC patch, but did debug the compiler error and worked with the GCC team on the fix. This directly resulted in a port of Xine to PowerPC. (LiViD and Xine are early projects for multimedia and DVD playback on Linux) Xine exists today, but it's unlikely any of my code is in it. While the GCC fix is not my code, the fix itself still endures and exists because of my interaction with the project.

It's a newer example, but code I wrote simply as a demo for the Cairo graphics project back in 2004 became integrated into Tuxpaint and is still used today for rasterizing SVG graphics into stamps.

I posit if you want to make sure your code survives you, write video game code.

Nevertheless, my own examples are all non-games. In the early nineties I wrote a program in Turbo Pascal to manage grades and print report cards, I heard one elementary school in my home town was using this until 2012.

On one of my first web programming jobs, I made a cold fusion-like template interpreter and ecommerce engine in C, that was about 1998. One completely online-based company that we launched with this software kept on running on it until it was sold two years ago.

In the early 2000s, my startup produced a web content management system that I wrote most of the code for, and sometimes I still get usage questions about it even today (to be honest, knowing that code is still used in production is not a good feeling).

Oh, I just remembered: around that time I wrote some microcontroller code that went into a certain brand of PA systems for TV studios, I'm pretty sure that's still in use...

My oldest personal project is a chat place where RPG players can meet up and roll dice, I think that launched around 2003 in some incarnation and though it's getting updates and extensions from time to time, the core code is almost unchanged: https://rolz.org

In 1990, during a summer internship at GE, I wrote a program that scheduled electric motor production at like 7 factories around the country. You would download the next weeks worth of orders from their timeshare system, which seemed ancient then. Someone had done a time-motion study of each motor model and determined how much time each motor needed in different stations. They wanted each day's schedule to use roughly the same amount of time in each station.

This was after my first year of college and I really knew nothing about algorithms. I wrote a horrific program in BASIC on a PC that did what I know now is a greedy bin packing solution. It created a least squares metric and tried moving and swapping orders until nothing improved the metric.

I was shocked to hear that 20 years later they were still using that same program.

This door: http://lslwiki.net/lslwiki/wakka.php?wakka=LibraryDoor apparently I first published it there in 2004).

No, not a BBS door, but an actual door, written in Second Life's LSL (Linden Scripting Language). You'd think making a door should be pretty simple, but as the engine had no 3D primitive (prim) that had an axis on one of its edges, doors were often pretty awkward workarounds, either involving linking the door to a cylinder or worse, rotating and then moving when the door was opened or closed.

This script when dropped into a basic cube prim shapes it into a door, applies a texture and most importantly, cuts the prim in half so that the Z-axis ends up on the side and it can rotate around and act like a door in only one prim (the prim allowance was limited, so this mattered).

The script also has several workarounds for engine funkyness, including one where it automatically moves back into position after every cycle to counteract "drift" - otherwise, due to accumulated floating point error, the doors would slowly drift out of position when opened and closed many times.

I know it is still in use, because Second Life still forwards messages to my account to email, so occasionally I get gems such as this:

> [16:04] distresseddamsel: hi there, i just purchased your wooden slave kennels and i can't get into it. I tried to follow your istructions on how to change the group, but when i edit the door, the option for group is greyed out.

Apparently my doors have been used in all sorts of items...

In 2001, I wrote a tag balancer (for HTML input, it also did some rudimentary XSS filtering) in PHP and then translated it to Cold Fusion (I was applying for a CF job and figured it might be useful to actually learn it).

I believe that both variations are still running, the CF version on Metafilter, and the PHP version was used in B2, which became WordPress. A few years ago, I was asked by the WP team to relicense the code from GPLv2 to GPLv2+ and sure enough, it lives on with relatively few modifications in WordPress: https://github.com/WordPress/WordPress/blob/b1804afeaf07eb97...

Perhaps most notable, is that I wrote it w/o having taken a compilers class or having much (any) understanding of stack-based parsing, but it still lives on, so I guess it was good enough to get the job done.

The suits also made a decision to open a third call center based on some staffing and cost analysis done by me and my boss. We used two totally different models (and argued a lot about which model was right). The director said, "The conclusions you guys came to were within 1% of each other, so it must be right. We're going to move ahead with the new center." That center is still up and running.

The thing that gave me chills was that no one told me the analysis would be used to make a $25M decision. I thought it was just skylarking and hacked it out with some formulas in a 3-page Excel spreadsheet in about three hours.

I was a teenager and around 1998 I wrote a Delphi program as a mother's day gift for my mother that works as accountant in a big public institution. The program automated counting banknotes (they still have some people that want to receive their monthly salary in cash, and they have to count the total amount and the number of each banknote kinds separately to catch errors). It was just a loop with modal dialogboxes for entering each person's salary in 2 ways. The program also generated a text-file report and allowed to print it.

I was a noob, and the code is horrible, I even used floating points (doubles) for money :/ so there's accuracy bug that happens for big enough numbers. They apparently still use that program (at least a few years ago they did), and they divide the numbers before they become big enough as a workaround for the bug (but then the reports have to be fixed by hand).

I wrote an expansion to the original SharePoint Team Services (STS) back in 2002. I was told recently by a student that their former employer (small mom-and-pop biz) still used STS and my software was why.

It was called the SharePoint PowerPak; it added a few features that "inspired" built-in functionally in later versions. Was primarily written by hacking apart the insides of STS and sending a few emails to some MS folks to get clarification on some undocumented thing that I was interfacing with. Color-coded calendars, categorized content in document libraries, tasks with an "email assignee" workflow, a Windows XP theme for STS, and a few other features. Was actually really proud of that one!

I then worked with another dev on a search add-in for STS called SharePoint PowerSearch. It was clever in that it used the little-known "_search" target for <a> elements that, basically, opened the link into a sidebar frame that IE had back in the day. The mom-and-pop business had that installed too.

Those tools, along with a community site I ran, blossomed into the SharePoint training and consulting company I own today.

So that's two 14-year old products still in use at a small business in the Philadelphia area. Made me smile to hear about it.

A few things that I wrote as far back as 2000 and 2001 are still in use. Just checked one right now and the login screen is still the same - no doubt passwords have changed, and it says it's running on php 5.5.9 on ubuntu - they've done some upgrades, and I can't imagine the backend is 100% the same. however, the url structure was built to do something funky, and that is still in place, meaning they very likely didn't throw it all out and start over (and the login screen is the same too).

Had another call from someone last year saying "x is broke" and... piecing stuff together, I realized they were still using something built in 2002, and using it 13 years later (now 14 years). Trawling through old code was weird - a mix of pride - much of it was pretty readable and understandable - and regret - many 'cut corners' I wish'd I'd not cut now, as it made the fixes take longer.

That said, I think there's something very useful about having to deal with your own code 5-10 years after the fact. You'll have a greater appreciation for why 'the right way' is what it is, and ime, I've found that code tends to be more maintainable and understandable by others when it's been written by someone who's had to maintain old code themselves (usually their own).

Doesn't mean newer/younger folks can't write good maintainable code, but it's a skill that seems to come with age more than anything else.

About 15 years ago, I wrote an entire web-based system for managing an online grocery delivery company. The whole site runs off of version 2 of that content management system, which had lots of the version 1 code in it, which is now 21 years old.

And yes, they are still running their whole business off of that unmodified system today! I should have put them onto a monthly maintenance plan. ;-)

I'm not actually sure it's still in use, I hope not. I wrote a small Python script for synchronizing student address for a student organisation at the local university.

The students would forget to tell the student organisation when they moved or got a new phone number, but they'd always remembered to inform the university.

Importing data meant getting an email, containing a CSV file, parse the data and lookup the students in our own database and update their information. Because I'd just setup the qmail mail server, and learning about .qmail files and mail queues in general, I just hooked the script into the .qmail file. I figured it would save me the type of dealing with the IMAP server.

I think it was six years later, maybe a little more, when I got a call from someone that the student organisation, asking if I could explain how the student address information was kept up to date. They knew that the data came from the university administration, but it just sort of disappeared into the belly of the mail server.

One bit that I hope is gone is the ONC RPC stuff I wrote for talking to the credit card processing engine we were using back then. That was pretty ugly.

It tags the files appropriately, and makes a release suitable for upload to a well known private music tracker.

I released it to a private group of people, it has been kept a secret within that group mostly and has since been extended to include support for many different services and integrated into complex automated systems which automatically rip, package and release new music as it is released and also old music as it is added to the request feature of the site. I released a much better pure bash version when I was 15ish I think, but many people still use the abomination of a userscript which writes a bash script as far as I am aware.

A website demo using XML and XForms before they were standardized scripted into HTML that's still running at a site per an old friend. Well, at least a few years ago. It was one of about 30 examples in a set. What they couldn't figure out is my site was blank on every browser despite everything organized by a INDEX.HTML file they loaded. The trick: one of the letters in either the file's name or name a preprocessor gives it isn't the English letter it appears to be. ;)

And apparently they didn't delete the shit because (a) they're lazy and (b) people just skip over it assuming it's a browser error instead of typing "INDEX" in their address bar. So, they left it in there as a successful example in a demo set. I got a glowing recommendation, too, since I showed the original ("bleeding-edge, web tech!") to the person in charge who also thought the demo glitched. Funny all around lol.

Note: This was a bullshit project rather than paid or important work. Not what I'd do if someone paid me for quality work haha.

Back in the late nineties I was working for a small ISV and was a dev lead on a project to develop a C++-based visual programming environment and runtime for monitoring SCADAs and PLCs. It got used by a few customers, but ultimately wasn't successful and was discontinued when the company did what we'd now call a pivot.

I moved on to a company in the financial sector and my employer acquired the rights to use this software (a decision I had nothing to do with). We ended-up using it as a way to embed customer-specific customisation scripts into a cloud-based product - something that it had never been designed to do, but which ultimately worked quite well.

A couple of weeks ago I finally replaced it with a much smaller and more focussed body of C# code, 16+ years after it was initially developed.

Oldest surviving code dates back to 2006. It's a simple PHP script, that generates an Excel file(without the help of any libraries. I was really into not-invented-here then) containing information about banners shown for a week. If it works, don't touch it, right?

Second one dates back to 2008. It's a webapp written in Django for real estate agents. Full of bugs, requiring careful input of data in order not to mess up the listing. I went on a 3 day hackaton somewhere back in 2011 to fix all the bugs for free and got some very angry calls, because things weren't working like they used to before. Turns out people were aware of these bugs and made their own workarounds. I was forced to roll back all my changes and backport just a single change - the ability to reorder images by using drag and drop.

I was the author of a 2002 quality assurance software written to receive images from a microscopic camera attached to a robotic arm and turn them into 3D models as part of a friend's doctorate thesis that was later sold to mercedes as a prototype.

One German engineer later noticed that it contained my copyright, located my address and subsidized me every time the system was commercially sold up until 2008. Not sure if it is still in use, but I am thankful for his sense of justice.

The oldest code that I wrote that I suspect is still in use is RoboGen, an editor for robots.txt files, that I wrote in Visual C++ 6 with MFC. I remember working on it while not paying enough attention in my high school physics class. We were allowed to have laptops in class at the time. You can see it at https://rietta.com/robogen/.

The oldest code that I distributed - it was written by a friend of mine - is Whois Web Professional which was a whois client written in VB6. I know it's still in use because I have to maintain the version file on my website and even keep my server running Apache because its update checking was written by a 12 year old in WinSock and doesn't handle the protocol very well. If I change anything, the VB6 program crashes on startup and I get emails about it. You can see it at https://rietta.com/whoisweb/.

In a mostly proprietary environment that's really hard to say. In the world I live in (Germany software business world) few things get really deleted once they made it into the daily life of a company. Nearly all companies have code that was written like 5 years before their foundation by one of the glorious first 3 guys and that is still used in most of their major software products. The tricky part is getting even awesome software into these daily routines.

In 2009-ish I wrote a Java-based templating system for Autosys' Job Information Language. If you don't know it, Autosys is a horrible, horrible, job management and scheduling system. You define these little files (.jil extension) that specify not only the job definition (command, user, cron-like schedule, etc.), but also its dependencies (which job must run before this one, what runs after...). Nothing wrong with that approach, per se, but there's essentially no way to validate the correctness of a job and its dependencies until it's running live in production. Often jobs would fail to run when you expected, or become quietly orphaned by some change to another upstream job.

So I wrote a disgusting (yet fluent!) enum-based monster called JILT (Job Information Language Template), that required that every existing .jil file be rewritten as a statically-typed java enum which could then be used to spit out the entire tree of validated .jil files. The nice thing was that your job dependencies were now enforced by the compiler and could be included in CI. But the actual inner workings were a hot mess. And of course, now the support teams have two systems to maintain and ensure they remain in sync.

This was at Goldman Sachs and I hear it's still under active development by the support teams...

Was tired of Aumix back then being buggy, so I wrote my own replacement. I think my biggest wtf moment was this being included in the FreeBSD project (at least 4.0), and many Linux distributions also, so it's now out there forever.

I doubt this will impress, so much as amuse. But I'm pretty sure the oldest thing I've written that's still in use is a series of popular scripts used in various Warcraft 3 maps and mods. Written circa 2003 if memory serves. Mostly they focused on adding RPG-like elements to gameplay: camera lock on individual PC units, unit swaps to "upgrade" character classes, and so forth.

At the time, JASS (Blizzard's scripting syntax) was largely procedural, so this was some brute-force work that was a real bear to make usable across different mods.

Still playable, though, and still enjoyable.

I do have a 21-line python script that I still use which I initially committed to github in 2008, so that's certainly a contender (first internship started in fall 2004).

The script is an expansion on the web server one-liner: https://github.com/imnotpete/odds-and-ends/blob/master/pytho...

edit: the one liner: http://www.garyrobinson.net/2004/03/one_line_python.html

My first fulltime job as a developer was back in 1997 for a state university. The wheels of change are slow at that kind of place so it's possible some of my code is still running.

The oldest that I know is still in use is code for an ecommerce outsourcing company I worked for in 2003-2005. ASP/Javascript. Pre-jQuery Javascript too. Fun times.

The oldest that I'm still supporting is VB6/ASP code written in 2006, though the entire software is older than that. It's for "contingent workforce management" (temp labor) and handles the 3-way relationship between client, the supplier, and the worker. In it's heyday we were processing over $2B in payroll annually. It's now down to one client using it. The relationship is very weird too: it's me->hosting company->business company->end client. But I only have to do 1-2 days of support a month and have a pretty good contract for it.

I offered to help fix it but I was kicked out of the building for flirting with the claims department manager (actually a close friend of mine). This one may actually no longer be in use because I never split the UI and DB and it's not supposed to handle multiple users at the same time if you don't, IIRC.

When doing a school project, in 2009 or so, we had to record a lot of sounds, each linked to an image. The usual process of recording, cutting the ends of the sounds and saving with proprer file name was too cumbersome (we had multiple languages and some variants to record, bringing the total sounds to over 100).

Instead, I coded a small utility hidden within the program to show the image, and allow to record with a single keypress. It is precise enough that you don't have to cut it afterwards, and it auto-saves to the right file name.

To this day, I didn't find a better way to record lots of small sounds, and since it was written in C# and XNA (which has been killed since then), I keep a Windows computer around just to run it, when I need it, about one or two times a year.

There is little incentive to rewrite it until it stops working altogether, since the use is so infrequent, but each time it saves me several hours of boring work.

The VoIP site I'm particularly proud of because it was a cross-browser fully AJAX'd (Single Page App for the kids) site built before we'd ever heard of jQuery or Prototype...and it's continued working without a single update for 12 years. PHP 4, WSDL Java services and hand written Javascript that worked in IE6, Safari and Firefox (Chrome didn't exist yet but it works there too).

I still have an excel sheet that I wrote to perform mortgage calculations. The timestamp on the file is 10 March 1994. The latest version of excel can still open it and it works.Although it exists, it's not in use.

I suspect all the stuff I wrote back in the late 80's and early 90's has long been switched off at some point, which is kinda sad. It would be hard to run today: EBCDIC mainframe stuff and 16 bit PC stuff.

Unimaginatively named "Music Player", it remains the only music library organizer that I've used so far that completely ignores all the ID3 tags and respects the way I manually organized the files into folders (artists) and subfolders (albums). That's supposed to be a feature, not a limitation. Back then I had a lot of pirated MP3s with horribly inconsistent ID3 tags ;)

Odd list. You can have a very successful developer career without ever needing to write any of those ever. I'm a little over 20 years in now, and have never needed to do any of that.

Maybe in the 90s, I might have actually built a linked list in C for whatever reason, and I guess you could define graph traversal to include walking a tree pulled out of a database. But the rest are things that The Universe Provides For You(tm), which one would only ever reproduce in School, a Job Interview, or a Poorly Chosen Hobby.

As to actual rites of passage? Ship Something that real people actually use. Build an entire thing, be it a piece of desktop software, video game, web application, mobile app, etc. from bottom to top and send it out in to the world fully formed. That, in my mind, is what we're here for.

1. your own MVC framework You should do this to appreciate why developers of other frameworks make the decisions they do. I gained so much wisdom from this.

2. Parsing HTML with regex (see here - http://blog.codinghorror.com/regular-expressions-now-you-hav...)

Seriously, just DONT DO IT(tm) -- but if you do, you will eventually learn why you don't want to do it this way, and you might get pretty good at regex expressions

3. Your first mobile app published to the app storePublishing apps to the Apple app store has given me a deeper appreciation for paying attention to the little details. Also, making native apps is a completely different paradigm than web apps because shipping code with logic errors has such a high cost and delay to fixing them.

4. Port an existing library to a new languageI long time ago I ported a recipe parsers from Ruby to Python for a paid gig. It was such a good learning experience because I had a perfectly functioning reference implementation, which allowed me to go deep on getting the details right.

I had to replicate test cases, documentation, scaffolding, and the code itself while being aware of the gotchas of Python.

Dive into someone else's imperfect at best code and make it work. After finishing the final project for my 2nd programming class, I helped someone else make their's work. In the context of what could run on a PDP-11/70 running Version 6 UNIX with 24x80 CRT terminals, it was rather neat, a semi-real time air traffic control simulator game, with planes coming from the upper corners and crossing paths as they went down to the catercornered runway.

Great idea, better than mine, but the code was awful, had three global state variables X, XX, and XXX ... plus U, UU, and UUU for the UFOs he'd added to make the game more fun ^_^.

I helped him reduce the complexity by removing the UFOs (it was still quite challenging enough), and getting it to work in general. This prepared me for the many future jobs I took working on the code bases of others (one of which, for example, taught me red-black trees for real), and which soon enough led to the extremes of software archaeology when you can't even ask anyone about the code.

Not that you necessarily want to seek out such work, it's hard and often thankless, but at its best it's also what paying down technical debt is about. And code you've written long ago can also be rather foreign when you come back to it....

For me, it was implementing a large bit of the C standard library. I had just blown an interview at Microsoft in 2001, where I stumbled over a whiteboard implementation of strtol, and I thought that I needed a serious upgrade of my understanding of library implementations and the algorithms that are used in them.

Every developer should also implement all the basic data structures and algorithms -- and then never write their own again! The process, however, definitely improves your chops, helps you understand the trade-offs inherent in choosing among data structures and algorithms, and gives you an appreciation for what's going on "under the hood."

The phrase 'rite-of-passage', to me, carries negative connotations - something you have to do, something tedious, something necessary. In truth, there are no such projects.

However, in terms of projects popularly considered to be commonly implemented by newer programmers that do hold benefit, in network programming, I would say a traceroute implementation. Server-side, I'd say any multi-node cluster system, preferably diskless. Any embedded system. An RDBMS system. A NoSQL system. An open source intelligence system. Any computational linguistic system. Any i18n/l10n heavy project.

Tensorflow has a whole bunch of tutorials, but those are the "Hello World"s of tensorflow, not of neural networks.

In order to get started with neural networks, begin with drawing simple neural nets for basic operations like addition, multiplication, XOR. Just represent boolean tables as neural networks.

Once you can do that, move on to implementing the algorithm yourself. A simple 3 layer network is enough to understand how the concept works. 4/2/2 nodes is plenty. Just understand how the calculations work.

Then move on to a framework - only after you understood the math. The machine learning course on coursera by Andrew Ng(?) explains the algorithms.

As some comments suggests, it's not clear what you want from the professor. If there's no clarity from your end, it's very unlikely the professor can help you (even if you get a chance to meet them). I recall my thesis adviser saying something like, "I receive >100 emails/day from various students requesting to work with me". This was in 2001-2002.

I "hustled" few professors and got some face time around 2001 time frame. But I was out of undergrad (not high school as you requested). These are the things I recommend.

0) Have clear goals on what you want from the professor (and what you can offer too). I showed interest and competence in doing research and I wanted funding from them.

1) I worked extensively in couple of areas (Genetic Algorithms, Simulated Annealing, Finite Element Methods, Optimization of Manufacturing Processes) and published conference and journal papers before requesting a meeting. I am not suggesting you do this. But you need to show you have done some work to warrant face time with professors.

2) After you have done 0 and 1, email them, call them and somehow "stalk" them "respectfully". To meet the professor I did Master's thesis, I wrote to him few times and called him. But finally, I waited in front of his office few hours every day and finally got a chance to meet him. I eventually got funding and completed my degree with him.

3) Alternately, if you can attend some conference (figure out a way not to pay but attend the conference) and meet them there. That's a big plus, IMO.

4) Write to the professor's PhD students and start communicating with them. Learn from them and do your research and build some projects/ideas and use it to meet the professor. This is a "back door" entry in to professor's lab. But PhD students are quite helpful and can guide you in to building a "portfolio" of projects.

HTH.

Early 40s here. No problems.

I get a sense that senior devs who complain about age discrimination are the ones who haven't kept on learning, and haven't been keeping their skills up to date.

I could be wrong, but I have no problems finding opportunities. I see others my age or even much older who exhibit enthusiasm and a youthful wonder and they seem to be swimming in opportunities.

Nope. Not at all. Feels awesome. The whole world is trying to exploit and be the boss of developers and that is power. Power for the developers. Even when I an 75 and about to die someone will be trying to hire me, lol. I already make more money than all my professors and almost everyone I ever went to school with. All I have to do to stay employable is study a few hours a week to stay up to date. Sure, I won't be able to work at established companies that have the luxury of age discrimination, but those are the boring companies with the shittiest managers. Barring a head injury and death there is nothing that can stop me.

I'm 42, and I'm not particularly nervous. But I've made it a point to continue learning aggressively throughout my whole career and to this day I still spend a lot of time on Coursera and EdX taking classes, and I keep subscriptions on Safari, Lynda.com, Pluralsight, Egghead.io, etc. so I can constantly keep updating on new stuff. Lately I've been working pretty hard to expand from my core base as a Java developer, to pick up some skills on the "data science" side of things... R, Octave, (more) Python, machine learning and the like. And for the past 4 years or so my dayjob had me focusing on pretty trendy / sexy stuff like Hadoop, Spark, Neo4J, cloud APIs, etc. So unless something really crazy happens (AI comes along and eliminates all development jobs) I expect I'll be able to stay employed in this field for the forseeable future. And I'm working on a startup of my own on the side anyway.

As to whether or not age discrimination is an issue... if it is, I haven't really noticed it as such.

I feel great! For me, age doesn't really factor into it. I'll probably push my last code from my deathbed - hopefully in the form of committing my conciousness (kidding, not kidding).

My career just keeps getting better. It's not hard to stay up to date if you stay interested and engaged. And if you're interested and engaged, you find yourself not really aging in the way a lot of people do.

Another nice benefit of aging that's helped my career is wisdom earned from experience. I started at AOL in '98 when I was 16 (it was cool then) and have worked in the industry since. There's not much in the way of team dynamics or project mishaps I haven't seen, and that gives me clarity and calm during crisis, which tends to make people want to put me in charge.

I've also learned a lot about interpersonal relationships, confidence and finding mutual benefit. While those aren't typically skills most people associate with staying relevant as an engineer, they are skills that put you in positions to succeed in any walk of life.

I'd say the problem for some veteran developers isn't aging itself, it's getting into a mentality of aging. As long as you embrace the new in technology instead of clinging to old methodologies, you'll be fine. I know developers much younger than me that gripe about new frameworks and libraries like it's a chore to learn. It's still as exciting to me today as the 2400 baud modem I got from my parents in '92.

Why are we still using Mainframes?
6 points by parialegend  1 day ago   14 comments top 6

lucozade 1 day ago 1 reply      
In my experience, mainframes tend to be used where functional requirements are very slow moving and reliability trumps flexibility.

I don't know of any case where a mainframe couldn't, in principle, be replaced by a server farm. However, maintaining a sufficiently reliable and secure server farm is a specialist job too so the benefits aren't always clear cut.

Ease of migration is really down to what the mainframe is doing and for how long. In practice, they tend to be in place for a number of years in hub-type roles e.g. general ledgers, payment systems. That sort of thing. The effect is that extricating them is extremely complex and expensive.

However, these issues aren't really limited to mainframes. We have the same problems with trying to extricate Sparc Solaris applications. We generally want to replace them with Lintel as we use them in most applications. But doing so is horribly complicated as they're embedded in byzantine flows that few understand and the systems often assume a level of hardware reliability that commodity boxes don't have.

YeGoblynQueenne 1 day ago 1 reply      
>> Do we have any alternatives? How easy is it to migrate?

Oh god, no, don't even think about it. It's hard enough migrating away from a code base in Java, written 10 years ago and that runs on pretty much anything. Imagine how hard it is to migrate from a code base written in languages known best by engineers in retirement, that only runs on extremely expensive supercomputers made by almost a single company (IBM).

But the worse thing is that you can't just pull the guts out of the software that runs all the transactions of huge financial organisations. You can't just throw a switch and stop all financial activity in a big bank, while you swap a new system in place, because every second of downtime costs millions. Millions! Who is going to take the responsibility for that?

So change never happens because nobody dares make it. One day mainframes will outlive the last people who can program them competently and then we'll all be in trouble.

dsacco 2 days ago 1 reply      
Glad you asked. This is a list I like to call, "how to become an extremely effective and formidable security engineer."

1. The Web Application Hacker's Handbook

Probably the first book you want to read; this will teach you the core mindset you need for finding security flaws in web applications as well as give a very strong foundation for the different classes of vulnerabilities.

2. The Mobile Application Hacker's Handbook

Good supplement to #1 for application security, obviously focused on mobile apps.

3. The Art of Software Security Assessment

The bible of the security industry. Especially instructive for source code review.

4. Security Engineering (Ron Anderson)

Supplements #3. Very instructive for injecting security into the overall SDLC and designing secure software.

5. The Tangled Web

Excellent historical background and good high level overview of many information security topics. Every engineer should read this, even if they don't work in security.

6. Gray Hat Python

Very hands on, good introduction to aspects of reverse engineering and the typical work an e.g. security consultant will do at a top firm.

7. Practical Malware Analysis

Very good introduction to malware analysis.

8. Practical Reverse Engineering

This book, along with #9 will teach you everything you need to know to effectively reverse engineer software for security-focused analysis.

9. Reversing: Secrets of Reverse Engineering

10. The IDA Pro Book

You'll want this if you have any plan to work with IDA Pro at all, which is the gold standard for decompiling and reversing software.

11. The Shellcoder's Handbook

If you'd like to write exploits after you're done reversing software to find an exploitable bug, this is a good book to pick up.

12. Cryptography Engineering

Very solid and broad introduction to cryptography. Every engineer should read this, even if they don't work in security.

13. Introduction to Modern Cryptography

This book, along with #14 is what you want to read if you're going to work as a cryptographer or cryptanalyst professionally.

14. Handbook of Applied Cryptography

--------------------------------------

Theoretically, these books should resolve your known-unknowns and your unknown-unknowns. Anyone who reads and works through the list should be capable of designing secure software, finding errors in white and black box source code reviews and finding errors in white and black box penetration tests.

If you're looking to get into this professionally, feel free to contact me if you have any questions and I'll do my best to help.

Guest98123 22 hours ago 2 replies      
OP, we're close, I'm averaging 130 USD/day for 2016. It jumps all over though, and I might see 200 USD days, and 90 USD days, even though traffic and clicks remain level. It's from a single site. About 60% of my users run ad block (young, male, tech audience, mostly on desktop).

Ad revenues drop year after year. I think it's a dying business in its current form.

I think an API should be available for advertising. The API would provide the name of the advertisement, the description, colour scheme, image, and more. Then, developers can use that information to work the advertisement into their site in an attractive and seamless manner.

http://i.imgur.com/9ecRa5o.png

An example is above. Instead of having a leaderboard advertisement for Chrome, HN could get the advertisement details, and insert it into the site to resemble a post. Every site could then style the advertisement their own way.

I think it's less annoying to users, fast to load, users are more likely to read and click it in comparison to a banner they're blind towards, advertisers would get more for their money, and publishers don't need to destroy their site with gaudy flashing boxes that everyone ignores. It's a win-win-win situation, and my vision for the future of advertising.

Personally, I'm looking to drop AdSense in the near future and try alternative revenue streams. I worked hard to develop my community. I don't like pushing some ugly, irrelevant, tracking filled ads on my users, in exchange for a few cents on every thousand impressions. It's a business that needs fixing, because advertisers are getting ripped off, users are bending over or forced to install ad blockers, and publishers need to keep pushing more and more advertisements to make the same revenue they earned last year. I'm surprised Google hasn't been more innovative in this space considering it's their bread and butter.

I think that educational technology is still at a point of "throw it at the wall and see if it sticks". I also think a lot of technology is being deployed without adequate professional development for teachers.

They have the technology, but haven't been gotten the proper level of training nor had the proper resources to develop effective curriculum using technology.

Thus far, effective programs always seem to have a "rock star" teacher/instructor at the center, going the many extra miles needed to establish gravitas.

It certainly ignores a lot of human productivity studies that indicate people rarely work at full manual labor productivity past 8 hours and full creative work productivity (including problem solving and often socialization skills) past 4 hours.

It certainly may be the case that they actually are interested in seeing interviewees past such points in a somewhat controlled environment.

Such "gauntlet" interviews seem common among large technology companies and while I think some of it is a semi-intentional attempt to push interviewers to limits to see how they react, I think it's also just as much "everybody else does it" and that continual momentum of existing interview processes. Which is precisely how such hazing processes in organizations get normalized and their problems ignored over the long term. (Yes, pushing someone to the limits of their productivity is strenuous activity and the very definition of hazing.)

I understand the technical limitations.

But here's what I don't understand at all...

Has anyone ever been sailing? On yachts we have radios, but these radios are designed assuming the person operating it might be completely ignorant.

So we have this literal red button, you lift a flap, hold down the button and the radio sends an SOS with complete GPS coordinates and boat name on Channel 16. Then it leaves it on channel 16 so you can describe the emergency.

So back to smartphones, on smartphones we have dialer apps, these apps know when you dial 911. Why in holy heck don't they have a big red button on-screen which when pushed sends your current GPS coordinates USING VOICE over the open line?

Here's what we need to do that:

- Dialer app. CHECK.

- GPS. CHECK.

- Some kind of UI. CHECK.

- Text to voice system. CHECK.

We have all of the components to roll out a system TODAY which tells 911 via voice where you are calling from. It would almost be free, but we haven't, and nobody is suggesting it.

Everyone is talking about these crazy complicated standards that will, best case, be available in 2021 and cost ungodly amounts. I am talking about using voice which the operator themselves can type in.

Am I mad here? Why isn't this a thing? Why doesn't the dialer even DISPLAY GPS coordinates when you dial 911?

Seriously I bet if someone made this a big deal we could get Apple and Google to sign on almost immediately and this would be available within a year. All smartphones already have all of the prerequisites to do this!

You'd be really surprised how well the humans in a 911 center cope with antiquated technology. Visiting the center in Cambridge, Mass, I watched a dispatcher -- calm enough to almost seem disinterested -- do everything perfectly by being the "human layer" on top of the old system.

She entered scattershot information from a frantic caller, and using a combination of keyboard shortcuts, foot pedals (yes, foot pedals), and stand-up-and-hand-signal-to-a-colleague-while-keying-a-mic, dispatched an ambulance within seconds. Way faster than the caller would ever realize.

You're not just replacing software/hardware, you've also got to make allowances for the humans in the system. Little things make huge differences in those situations, so throwing the old system out is painful. Evolving the current one (as davismwfl pointed out) is challenging for its own reasons.

Doesn't mean it isn't important. Just hard to do.

davismwfl 2 days ago 1 reply      
So having done a lot of work in the 911 systems for years, I have some first hand experience here.

First, most pizza apps are just that, an app. That app has access to your phones location data through GPS and some even use WiFi location services. Hence it can send a nearly exact position to where you are standing.

Contrast that to the standard phone network and systems ANI/ALI solution, which still does not (completely) support GPS coordinates at this point. In addition, while there were phases (phase I and phase II) of cell phone location compliance put into place by the federal government, most networks and phone companies lagged far behind in implementation of those standards. On top of that, city and county 911 dispatch centers (PSAP and secondary centers) also have to upgrade their phone and CAD integrations to support better location services.

As for why it isn't being disrupted. Simple, looooooooong sales cycles for an extremely limited market that is vigorously defended by the incumbents. Seriously, it isn't rare for a 2-3 year sales cycle for a lot of 911 components and systems. 18 months is about the normal when it involves critical systems with 12 months being probably the fastest you see anything change. Not to mention, the partners you need involved to make a solution work and be palatable to the 911 centers are the exact same companies who want to keep you out of their market, so it isn't easy. Not impossible, just not very probable without seriously deep pockets to support what would likely be a 3-5 year development to first sale. It makes selling to enterprises look like a fast process and cake walk.

Because 911 was designed for ordinary landline telephones, before GPS existed, before computers existed. It's just a telephone call, not an app running on your phone.

Granted, it could rely on the software running on your phone to add information for the dispatcher, but not everyone has one, and not everyone who does has the same kind. And that's a good thing!

So it takes standardization, and government regulation. Standardization can work pretty well when there's a nice tight feedback loop with customers who are interested in the results (web browsers, for instance). How many telephone customers would switch phones based on the details of how well the phone supports 911-related features? It's not like we can test them without actually calling 911.

Government regulation can also work, provided you're willing to pay the costs: time and money. Lots of time, and lots of money. In fact, it costs so much for the government to regulate things like this that we end up in this exact situation. Phones have completely changed since the last 911 regulations were updated, requiring telcos to provide location information to 911 when the caller is using a mobile phone. It took years after that regulation was introduced before the telcos were compliant, and before all the local dispatch operations could use the information.

The same would happen today if new regulations were introduced requiring the phone itself to send this information; it would take years for anything to happen. (Though I bet Google and Apple could move faster than the telcos, they've certainly proved to be capable of that.)

And that's all ignoring the inaccuracy of GPS when inside of buildings, the time it takes for the phone to determine the location, etc.

Still, in spite of all of that, now is probably a decent time to start making those changes. It's been long enough since the last updates to the regulations, and new phones are capable enough now, that you'd have a decent chance of getting it done eventually.

Because pizza apps use the GPS chip in your phone to get the Lat/Long of your location, and sends it via HTTP(S) to the pizza shop. Currently, cell phones/cell networks aren't able to access the GPS chip on your device and send that data to the receiving party.

Maybe a possible solution (and startup idea) would be to have an app for initiating emergency calls, which puts the user into a conference call with an assistant operator at the app's developer company and a 911 dispatcher.

- If the user doesn't know the location, and they have given the app permission to read GPS data the assistant operator could check the phone's location data and chime in with the correct address in the conversation.

- If the user is unable to speak, they could send text messages to the assistant operator, who would relay them to the 911 dispatcher.

- If the user is unable to do anything more than pressing a button, and if they've given the app permission for this, the assistant operator could check the messages or other data on the user's phone to try and find out what the issue is (e.g. domestic violence.)

- The user could initiate a video call with the assistant operator who could theoretically be able to more accurately describe certain issues (assuming they are better trained medically) than the user themselves could.

I live in Milan, Italy. A few months ago I had to call 112 (our 911 equivalent) after witnessing a bad car accident while looking outside of the window. The dispatcher on the other side of the phone gave me my location (which was 100% correct, both street name and number) and asked me to confirm.I suppose this was possible thanks to E112 [0], but I am not 100% sure.

Actually, in Finland the local 911 equivalent (112 Suomi) knows your location: https://play.google.com/store/apps/details?id=fi.digia.suomi...

"The 112 Suomi application enables the automatic delivery of the caller's location information to the emergency service dispatcher (in Finland).Continued use of GPS running in the background can dramatically decrease battery life.

By using this application you agree to the following terms and conditions: http://www.digia.com/PageFiles/112 20Suomi/112-Suomi-app-user's-licence-agreement.pdfRegistry extract according to the Personal Information Act: http://www.digia.com/PageFiles/112 Suomi/112-Suomi-app-registry-extract.pdf"

I don't know many details about the problem, but I might suspect there's also a "perfect is the enemy of good" issue here; there are serious consequences for getting a 911 call precisely wrong, so it's better to be approximately correct and let humans do the work of narrowing-down. With a pizza delivery, if they drive up to 1234 Somewhere Lane and knock on the door asking for 1236 Somewhere Lane, someone's going to point out the problem (and if not, the cost is relatively low), so it's okay to be precisely incorrect.

It isn't just 911 in the states :: It is similar here in Norway and gives me a bit of worry... if I ever need emergency services, that is. I guess they can look it up, but it takes longer.

Here there is an app that will send that information to 911, without worrying about giving special permissions at the time of the call. I'm not sure why that isn't standard on cell phones everywhere, especially since phones generally come pre-loaded with apps. I know that landlines in the states send the information to 911, so I would think some people much smarter than I would be able to make an interface to go between the two. I suppose that would take some time, given how well the government seems to work together to get important things done these days.

Yet another example of capitalism run amuck letting people die in the name of profits.

The phone companies COULD upgrade to newer technology right now, but that would cost money.

Or...

They could wait until it is a crisis and then DEMAND that municipal governments pay for the upgrade.

Which would you do?

Because human society values selling pizza more than saving lives. If we really cared, we would have a 911 app as well and it would know exactly where you are if you use it to dial 911. But, nope, we don't actually care that much.

(This is not snark, in case you are wondering.)

What brotchie and petervandijck said, also:

* Put some effort into the design. Writing plain HTML while also indicating you have run a website and have front-end experience might seem contradictory to a potential employer. A nice font, simple layout and basic responsiveness would go a long way.

* A startup exit, even if small, is a considerable achievement. Consider adding "Acquired by $COMPANY", or if not at liberty to disclose the company name, something like "Acquired by large German corporation".

* Add contact information. If I were to stumble upon your CV online and be interested in hiring you, I should not have to spend time Googling for some way to contact you. Listing your email in the footer is sufficient.

* I assume not getting your degree yet is because of a few pending courses - no need to mention this here. You did the majority of the work and actually completed a thesis project. When you are invited to an interview, disclose it there.

* Some of the stuff you list (machine learning libraries, contributions to poker theory) sound really interesting. Is there anything you could link to here? Blog post, Github, etc.

edit: typo

When listing experience, it's best to follow the pattern:

I accomplished X, relative to Y, by doing Z.

For example for SocialInsight.io:

- Instead of "Instagram Analytics": Helped X customers increase their Instagram revenue / engagement / etc by Y% by building an Instagram analytics Software-as-a-Service.

- Instead of "Big Data on a small server": Enabled fast in-memory Instagram stream processing by develping an optimized in-memory storage format that brought the per-post in-memory size from 300kb to 30kb. (I have no idea what you did, but actually frame the technical achievement that made it possible.)

What'd I'd like to know if I were assessing your CV as a potential hire:

SocialInsight.io: Is it just you, or a team? How many customers? How much revenue? Did you individually do all the design, coding, marketing? or did you have co-founders / other employees.

Freelance Data Mining: What was the most impressive job that you worked on? How many jobs have you done? I'd drop the $80/hr, and don't mention Upwork. Could get away with replacing Freelance Data Mining with "Data Mining Consultant."

Affiliate Marketing, need things like:

- Built a successful direct response affiliate marketing business that funnelled insurance leads to brokerages.

- Developed a custom analytics suite which allowed me to increase conversion rates from x% to x% and decrease traffic acquisition costs by x%.

Professional Online Poker: This is super interesting.

- Funded my university study through playing Limit Hold'Em poker online.

- Contributed "blah" to modern poker theory.

- Ran analytics on opponent data to gain an edge, etc.

Things to remove:

- Note about girlfriend's death

- "Machine Learning before it was cool" makes you sound like somebody I wouldn't want to work with. Better to say "Pioneered the application of machine learning to blah aspect of online poker. Built out custom machine learning libraries to implement methods blah."

- "I believe that inbound communication should come to me. I should not have to hunt for it" Wording of this is a red flag for me. Also, no real idea of what Zophoz is.

Echoing petervandijck: Definitely create a LinkedIn profile and create (or list) your Github account.

If it's not on LinkedIn, you might even consider this site as your own personal hobby html page. No one will find it, no one will read it. Such is life, make use of professional CV sites to find employment. Put in that one day of effort it takes to make it real good, then relax and watch the interview requests flow like spice.

At the top, remove the large photo (or make it smaller).

Then write: "10 years of software development experience ranging from low level C all the way to front-end web dev. 7 years of data science experience. Startup founder."

Then write a sentence of the type of work you're looking for. (startup? freelance?)

Then list your experience, with dates, going back those 10 years of experience. Remove rates. (the 80$)

Also, you should put this on LinkedIn (regardless of how much you hate it.)

First of all, is a web interface absolutely required? It adds a lot of complexity to something that is no more than a couple of lines of Bash glue. For monitoring, you can just keep an SSH session to the Pi.

How i would do it, requiring no user input:

* Designate a hot folder on the NAS, where i put all the videos to be uploaded.

* Establish a list of what has been transferred (nothing initially).

* From the Pi, poll the NAS folder for files that haven't been transferred yet.

* If a file is found, cat file | curl --data-binary @- POST it to YT.

* On success, record the transferred filename.

* Continue polling.

Of course, you can quite easily bolt-on a web interface to this, by exposing some of the steps as API endpoints.
