> Two of them are special: NOR and NAND.

No, IMP does this as well. It has mostly been useful for memristor logic.

 A B IMP 0 0 1 0 1 1 1 0 0 1 1 1
I have a suspicion there is a more general mathematical law that says any boolean rule with a 1-of-4 split (either exactly one true or exactly one false) can be used for general computation, if you can make a NOT gate out of it. (Since AND/OR obviously is not workable.) So there should be six possible universal logic gates.

One-instruction computers intrigue me because of the possibility of making the processor out of a ridiculously low number of transistors. To that effect, I've always wanted to implement one that doesn't require a hardware adder for the instruction pointer. It seems like it should be possible. For example, each clock cycle the CPU would take the NAND of the bit pointed to by the IP and the bit adjacent to it (via flipping the LSB of the IP) and use the result to determine a new value of the IP using very simple logic (E.g. IP = IP<<1 | NAND(mem[IP], mem[IP ^ 1]) ). But surprisingly, I've never seen this done and the last time I approached it I didn't have the knowledge needed to choose an appropriate scheme and prove its usability.

Neat CPU. That and adamnemecek's comment made me do a quick Google to see if there's interesting results in OISC that you all might enjoy. Found an improvement on SUBLEQ that's pretty impressive. Original first and newest below:

http://hasith.vidanamadura.net/projects/subleq/

https://arxiv.org/pdf/1106.2593v1.pdf

"Our test results demonstrate that computational power of our Subleq OISC multi-processor is comparable to that of CPU of a modern personal computer."

I didn't see that coming for OISC projects. Pleasant surprise. :)

Hi Peter,

I've received my green card through my sponsor company 2 months ago. (It's a highly reputable fortune 100 company and I am building their core web product)

And I have a project that's getting traction and really want to leave the company and commit full time to it.

But everything on the web says I need to wait at least 6 months before leaving the company after I receive green card, otherwise they can kick me out for fraud when I apply for citizenship later. But some people also say this is just a myth.

So the question: Is this true and I am stuck with this company for next 4 months even though I really want to go full time on my project? Any ways to get around this? Thanks!

p.s.I know this is not a type of question that you may be interested in answering since it's a minority case, but I would really appreciate at least a one line comment on what you think (or even saying it's not something you can answer). It looks like it's not just me, at least 6 people are interested so far, we will all be grateful to hear from you!

I'm a UK citizen that has been looking at EB-1A all week (because of Brexit), I'm now sure I do not want to continue living here if we in fact do withdraw from the EU. My questions:

- How many of the 10 criteria must you actually satisfy? Is it a binary decision, i.e. proving 3/10 is the same as is the same as satisfying all 10. Is a positive decision 100% guaranteed is at least 3 criteria are proved satisfactorily?

- What is the standard of proof?

- When would my obligation to complete a IRS tax return begin, i.e. is it when the consulate adds an MRIV I-551 to my passport, when I arrive in the US an immigrant and CBP endorses it, or another time. This might impact when I would apply.

- How long would the EB-1A process take, how long does it take for a permanent resident to sponsor a spouse, can these applications happen concurrently, and are both categories current?

- What are the indicative costs?

Hi Peter,

Thanks for taking the time out to answer questions!

I am from India and am in US on H1B with gc process underway in EB2 category. I (along with a fellow friend) have been thinking of doing something on our own but are always discouraged by the immigration process. If we were to start something on our own, what are our options? H1b where you have a majority stake seems to not be an option. Is there an alternate way to do this?

I don't seem to satisfy requirements for O1.

Hi Peter,

I'm a Canadian citizen with a four year computer science degree. I've gotten a TN work permit twice, with two different companies over the past three years.

If I started a company with an American citizen and they opened it up, could they then hire me as a Computer System Analyst? Is there a minimum salary they'd have to pay me (e.g. could I get a TN and still only get paid $10/hour)? Is this a common way for Canadian co-founders to enter the United States or is there a better route?

Hi Peter,

I live in Central America, I have been working as a remote worker for US-based companies for around 5 years now, the past 1.5 years working for a company on Seattle, I haven't signed any formal work-contract but my current employer is willing to help me to obtain a VISA to inmigrate to the US (I only have a tourist VISA right now).

I'm also in the way to co-found a company with my employer as partner, I will get 16% of ownership over it.

What are my best options to move to the US?

May I still apply to an H1B visa despite not having a formal work-contral? (the payments records, Skype logs and emails are the only proof I have)

Hi Peter, Thank you for taking the time to do this AMA.

The company that I currently work for has offered to start processing my GC, but only under an EB3. I have a masters degree in computer science from an American University, (and I have about 4 years of work experience) so I am technically eligible for an EB2 (and since I am from India, EB2 vs EB3 makes a big difference).

My question is, if I go ahead with the processing, Once I have my I-140 and priority date, would it be possible for me to switch jobs keeping the same priority date? If I move to a company with the means (and willingness) to file for a GC under EB2, would they be able to keep the same priority date?

Just trying to understand if this is something worth fighting for? Or if I should just accept the EB3 filing, get my I-140 and eventually move to a company that will re-file it under EB2?

Hi Peter,

Thank you very much for doing this! I have two questions about Canadian citizens looking for jobs in America. Possibly, looking to immigrate to Americain the future. Also, If possible getting double/triple citizenship.

Let's pretend you are a Canadian citizen, recently graduated from computing science, that is currently living in Alberta, Canada. What is the best way to get a job in America? Should I apply for a visa as well or should they offer a visa sponsorship?

Then, let's say I get hired. What's the best way to get an American citizenship with the goal of maintaining my Canadian citizenship? I was originally born in the Philippines; would it be wise to get three citizenships (America/Canada/Philippines)?

Hi Peter, Thank you much for doing this. I am a startup founder who plans to obtain E-2 visa and uses it for residency during the first 2 years of business. I hope to transfer to EB-1 or EB-2 with National Interest Waiver (NIW) as soon as possible.

1) What are the possibilities and timeline for applying to EB-2 while holding E-2 with majority interest in the startup? (I have a Masters in CS from a major US research university. It seems to be a challenge to qualify for EB-1 within the next 2 years, but NIW looks quite possible to me.)

A major reason for the plan is that E-2 treaty with my country limits the period of travel out and back into the US to 6 months after the visa approval. After 6 months, it appears that I will need to renew the visa every time I wish to come back to the US, which would be a major time sink.

2) Would EB-2 give its holders complete freedom to travel back to the States without issues and to stay as long as they wish?

3) Are EB-2 holders required to maintain employment with the original employer?

If you have time: I would strongly consider to become a US citizen after receiving an EB-2. What is the typical timeline and conditions to transfer from EB-2 to US citizenship?

Greatly appreciate it.

What are the chances of me working in the USA? Does it really nullify my chances?

I have been working since I was 17 in jobs related and then very specific to programming, I'm 28 now.

Hey Peter!

I'm moving with my company (large Washington-headquartered tech firm) from London to California. They're applying for an L1B specialized knowledge visa as a blanket application. What sorts of reasons are people rejected for L1s? I'm very nervous I'll be turned down as I've heard horror stories about USCIS. Does it being blanket improve my chances? What % of people are turned down? I married an American a few years ago and was intending to move to the US to be together but it didn't end up working out - I don't think the paperwork ever got sent in the end. Would something like this impact my chances? I'm probably worrying unnecessarily. I'm 26, worked at the company for just over a year and have worked for a couple of other large tech firms in London before that.

Thanks

Hello Peter!

I am so happy to find you and this thread. here's my story: I am a Swiss and Sri Lankan national, female, been in the U.S. uninterrupted since 2002 on several different visas. F1-while at Wharton getting my MBA, then G4 working for the World Bank, then three different H1-Bs (2 corporate, one research think tank) and then since 2012 I have been on an E-2 for my start-up business.

So basically I have been in the U.S. for 14+ years already, paid taxes in the highest tax bracket, own two properties here, started a business and grew it to profitability in 4 years, so far provided employment to 6 part-time American workers. Additionally my start-up business is in career coaching and job search- and so I have helped over 400+ Americans land good jobs, including for positions at the State department, DoD, and the U.S. Foreign Service. My company has partnerships with universities like Georgetown and my team coaches close to a 1000 American students every year.

What are my chances of applying successfully for an Extraordinary Ability EB1 Green Card? Or EB2?

Thank you in advance!

Do you see new OPT STEM extension (24 months) and it's requirements be something that could be met by most F-1 student entrepreneurs on OPT?

Background:The new 24 month STEM OPT Extension [1] (effective from May 10, 2016) which requires employers to fill I-983 [2] (Lengthy Training Plan) has created additional barrier for foreign students intending to start/work with startup companies on STEM OPT Extension (which earlier was for 17 months with less regulations). Being an F-1 student myself I can say that, these regulations could certainly influence more potential F-1 entrepreneurs down the "job seeking" path as opposed to "job creation/entrepreneurship" path because it is much easier for bigger companies with resources to satisfy the USCIS training plan requirements/I-983 as opposed to newly born companies.

Hi Peter, first of all thanks a ton for doing this.

My first question is how much time it takes to get green card through employment for someone who's not from India or China.

My second question is, does it make any difference to complete my MS before starting the process, or it doesn't change the approval chance and/or delay at all? (MS is from a middle eastern uni, not US)

--Here is a bit background about me: applied H1-B 3 times, didn't get selected. Now the company that applied for H-1B for me is preparing to apply for GC for me next month.I have a BS in CS and 3 years of experience, and almost done with a MS degree outside the US, just need to complete my thesis.

Thanks a lot again!

Thanks for taking the time. For Canadians or Europeans with PhDs and a sufficient track record to make EB1 feasible, is it better to work at a research institution while one gets a green card, or is it better to just plow ahead with a startup and then do the EB1? Can you discuss pros and cons? I've seen many colleagues delay their startup aspirations while they wait for immigration reasons .. I want to understand if this is being prudent or a folly. I've heard the green card that you get as a researcher is nominally approved for that job title. Are there issues people face when they eventually attempt to become naturalized?

Hi Peter,

Thanks for doing this! I am currently looking at a unique situation, so I'm not sure if you would know about this. All I'm asking is if you would know anything from your experience.

I'm an h1b visa holder from India and I recently got arrested and charged with a DUI. After talking to my lawyer, he looked at the evidence (videos, breathalyzer tests) and says its basically a 50% chance at a trial. So I'm looking at a plea bargain. How would this affect my immigration prospects? The DUI itself was my first one and it was a simple DUI, i.e. noone else was harmed or injured.

Thanks

Hi Peter,

First of all, thank you very much for doing this.

My questions are about the USA Diversity Lottery (https://www.dvlottery.state.gov/), as I rarely see any discussions about it:

- Out of all the people you have seen who obtained a green card, roughly what is the percentage of them getting it through the lottery?

- Roughly how much time and money would the process cost? (I would assume it's similar to the ~2-4 years and ~$15K that a regular green card application cost?)

- Any other general comments you have about the lottery?

Thank you.

Hi Peter ! Thanks for doing this, I do have a couple of short questions.

I'm an employee of a large US Corporate and got a O1 Visa which I'm currently employed under. I understand that my spouse will be able to move here as a O-dependant, but won't be able to work which is a huge issue for us and will probably prevent us from moving out to the US unless we find a permanent solution.

I do wonder, what are my options of getting her a work permit besides her finding a job that would endorse her and going through the entire process?

From what I've read seems like the two options I have are:

- H1B so she could get a H4. I understand that last year Obama approved some H4 recipients can work, but I'm not sure what the criteria is. I know that it's only able to be filed by 1st of April, but I also understand that there is a premium fee that could be paid to rush things up. Would love your input on this from your experience.

- L1 so she could get a L2. Best solution it seems but getting a L1 is a lengthy process and needs a 1-year employment period which I might not have by the time we want to move.

Thanks for reading this, I would really appreciate your professional opinion on this !

I wonder what is the best structure for a US based company to have employees living in an EU country, such as Germany or Italy?

I mean, I assume they don't necessarily need a visa, and they can come to the US for limited time periods under the ESTA.

What is the best way to give them a salary and/or other common benefits? (health insurance shouldn't be needed, but 401.k or equivalent in their country would probably be a good perk).

1. I studied in a HCI (Human computer interaction) program where there were a mix of programmers and designers. I found that after graduation a lot of the designers were applying for O1B and were easily getting those whereas programmers generally stuck to H1B's even though some of the projects that were being shown as part of the application documentation were group projects. Is it harder to receive an O1A for people in sciences because their work is generally not visual in nature vs O1B which is for arts (or designers)?

2. My OPT ends this month (June 30th) and my employer filed for H1B starting Oct 1st. My university issued another I20 (called CAP GAP extension) which start July 1st. But currently I am thinking about changing jobs immediately as my current employer is suffering financially and I am not sure how long they may survive. Is it ok to do that during the CAP GAP period if my new employer is willing to sponsor H1B? I have read online where some people say its ok but others say its not.

Is there any reasonable explanation for not being "allowed" to leave the US, after filing for adjustment of status? Without advance parole, that is. Especially when a different class of visa (say an O1, while applying for EB1A) would still allow reentry? That can be rather annoying both for professional and personal reasons.

E.g may be an example persona of someone who qualifies? The examples that are given by the immigration website are olympic atheletes and such. That's probably someone who is way overqualified though. What's an example of a person who just barely qualifies, or who neither under nor over qualifies?

Hey Peter,

My question is typical in the SF Bay Area, H1B founder:

I am an American Citizen. Opened up a startup C-corp. Company does not have a lot of press coverage yet. I have a friend who would like to join my startup as founder, but have doubts about immigration issues:

- H1B

- EB2

- originally from India

- graduated masters from a U.S. College

- currently software engineer for another big company. Has been for several years

- just starting the green card process

As a startup we don't have much revenue yet. He is willing to give up his salary (just as I did) to become a founder. I am worried about H1B's salary requirement preventing him from doing this.

What options do I have for bringing him on board to my startup as a founder? What would be the best way to do this?

3. If I already have O1, then what's the process like going from O1 to Green Card? When can you go from O1 to Green Card?

4. If I already have O1, are there tricks to stay in the US and never go back to home country to renew it?

Also, from my friend again:

I know O1 visa is very specific for example O1 for producing or or O1 for acting. If your O1 is for producing you cannot do acting under that visa. Currently I have only enough experience only for producing. But Ideally I want to get O1 for producing and acting. My question is if you have O1 for producing, while you are at O1 you want to apply O1 for producing and acting, if I get denied is my O 1 for producing still good or it get waive? Or can I just petition to add acting in my current O1? If I petition to add acting and get denied does my O1 as a whole gets cancelled?

What sort of "investment" for the US based company do I need to make, so that I can secure a visa and what type of E visa should I be trying to get.

I know higher the better is probably preferable. But where is the sweet spot? $100k, $250k, $500k?

I do not have a PHd, nor a Masters or even Degree. However I have 25 years of IT experience and I am the technical / founder of my company.

1. Does starting a (small-at-the-beginning) bona fide technology startup is grounds for NIW? How difficult is the process in general (for a PhD in CS from a US school) and how many paper/citations on average do you see in successful cases?

2. If I succeed in my NIW case, can I later employ my brother (from the same nationality under E-2) and bring him on board as a cofounder later? Does it require substantial cash on his behalf?

Thanks!

A friend of mine feels that the H1-B system is rigged, that the big companies will get as many H1-Bs as they ask for and that smaller companies essentially don't have the same degree of access to that labor pool. My impression is that he is wrong, but I'm no expert. As someone who deals with this regularly, what's your takedo you think big companies are practically guaranteed to get H1-B workers? How disadvantaged are smaller companies (esp those without access to YC resources)?

Hi Peter, I'm a software engineer and working under F1-OPT status. I didn't get H1-B in the lottery this year. But I can maintain work authorization by extending my OPT for 2 years from now(STEM). My company told me they would apply for my green card after a year from my employment. Do I need to have a H1-B so that they can start the process for my gc? Or can they start the process while i'm on OPT?

thanks

Hi ..

A family member of mine works for DHS as a paralegal, more or less, and their department deals with illegal immigration into the US. They often tell tales of how illegal immigrants will commit heinous acts (rape, murder) or somewhat more pedestrian crimes (heroin possession, for instance).

Anyways, the most striking part about this is that it seems a lot of the judges who handle these cases simply don't care. Because these people are often deported and then come back a week later, not a lot seems to be done. Some of the criminals won't be charged, and it seems a lot of people on the in the system will just turn a blind eye. I'm not sure if it's apathy, or if the system is so inundated that they're just unable to keep up, but have you experienced anything like this?

Well it is trite to say it but Haskell has many examples of servers and idiomatic haskell will almost always use immutable data. Examples are web frameworks like Yesod and web servers like Warp.

I'm working on a toy stock exchange app to learn haskell and of course it will be mostly immutable. It will use some shared global state. This will have mutable reference using mvars or transactional memory but the "objects" themselves will be immutable.

Communicating between threads makes total immutability hard (maybe impossible?) unless you have a very clever threading model.

The key to a great API? Have the developer / designer of the API write the first set of client applications before the API is published externally. I have integrated with many dozens of APIs over the years and it is immediately obvious (and unfortunately too common) when the designer of the API has never been in the seat of the client developer.

Sorry for not pointing to specific examples, but things I really love to see in an API:

- Fully qualified URLs in all links (makes navigating and discovery in Postman a breeze).

- Ability to expand resources represented by links (even deeply nested resources) so I can get exactly what I need in a single request.

- The ability to specify what parts of the response resource to include / exclude, allowing me to slim the response to exactly what I need. More important in clients running on mobile devices where slender responses make a noticeable performance difference.

- The exact same URLs (including hostnames) for the test and production API, the difference between the environments being determined by the credentials used in the request. This greatly simplifies code in the client test and production environments.

- Security schemes that allow me to write serverless client applications (OAuth 2 implicit grant). This certainly requires more work by the API developer, but makes it possible to crank out all sorts of useful tools quickly, and massively reduces client IT overhead. This may not be appropriate for all APIs, but could be used a lot more often than it is.

- Along with the above, support for CORS so we don't have to mess around with JSONP and other hacks in the browser.

- If you make me eat your timezone, please please make it UTC. But spend a little extra effort and allow me to pass a timezone in, either as an account settings and/or request parameter (and a simple offset isn't good enough - support actual timezones so daylight saving is handled). It can be incredibly hard to analyze data in responses when you're constantly having to translate the time to your own to give proper context. Timezone support isn't fun but libraries make it pretty easy. This is more important in APIs that provide lots of transactional data.

- Let me attach meta data to resources - it doesn't even have to be a lot. Sometimes allowing me to slip in a handful of bytes removes the need for an entire database on my side.

- Be painfully explicit in error responses. State the obvious, especially in errors that are likely to occur at the beginning of integration such as issues with authentication, content types, payload structure, etc.

Related: anybody have some good examples of a good asynchronous API? This claims to be the standard, but it has confused many of our customers. http://restcookbook.com/Resources/asynchroneous-operations/

To summarize: send a 202 for the initial request, redirecting to a job URL. The client polls on the job URL, which returns 200 with progress information until it's done, when it returns a 303 redirecting to the final output.

One particular problem spot is that many http libraries automatically follow the 303 redirect, and some even follow the 202 redirect.

I definitely think we would have been better off just putting status and final location information as JSON attributes in the body rather than putting it in HTTP response codes and Location headers. Non-standard, but much less confusing for our customers.

Also, verbs are not RESTful. Verbs imply an RPC interface.

RPC (verb):

REST (noun):

I would like to see how the versioning is achieved, how the versions are incremented, etc?

Bonus points if it is in the Java ecosystem.

Ask HN: Next european hub Berlin?

drinchev 1 day ago 2 replies      
I've been living in Berlin since 3 years ( doing freelance web-development & my own "entrepreneurship" adventures ).

IMHO Berlin might sound cool as a startup hub, but there is a huge lack of talent. Companies are struggling to find a decent dev/design team, probably because the payment is way too low than average. It's true that Berlin is cheaper than London ( and overall Germany ), but definitely is not so cheap to attract good IT people to join your journey with those numbers.

On top of that, giving stock-options here is a bit hard ( legally ), so companies are struggling to offer some "virtual shares" of an employee pool as a compensation, which will never make you as rich as if you are one of the first employees of a unicorn.

Everything else from offices, meet ups, parties, nice food, international city is here and I think is much better than overcrowded and expensive London ( That's why I'm still here :) ).

London. Not Berlin.

Berlin is affordable but that's it. You won't find the best people, the best teams and a good legal framework.

The UK has a better legal system. The UK Ltd. is way superior to the German Ltd. and soon they will move away from the EU inherited laws which are too much market regulating. Especially consumer protection and labour law are just a big bummer for many and for startups in particular.

Besides, just check total fundings, exits, average fundings sizes, etc. then you see the difference. Berlin based startups got much moeny the recent years but slowly people question again the ecosystem since exits are missing. Ok the city doesn't have the startup history like a Valley or London but still. Clear successes are missing. The only huge thing was Zalando's IPO.

IMHO It's too soon to tell. If several other states do the same the EU will become a disjointed mess. Some polls say as many as 43% of Germans feel more power should come home. If other member states show intention to leave it could ignite a surge of support for Germany to do the same. Then Berlin would just be another really nice place to visit but, isolated in German laws and the same chaos the UK is about to experience.

The real challenge is we live in very fragile times and the EU is like a big Jenga game, as parts start to slip away the entire thing could easily topple and drive Europe back into a chaotic state not seen in many people's lifetimes.

Based on my experience with SaaS, those that do offer Open Source software, are only open sourcing the core of their product. There is typically a whole suite of tools and add ons that expand their core offering into something that makes it more beneficial for companies to just go with the SaaS offering. Deployment and monitoring are two pieces that come to mind.

twa927 23 hours ago 0 replies      
One possibility would be to have a third-party service that would handle the instantiation of a service from some declarative description. Say, you specify a docker container and the service would run it and would tell the given server is running as the specific docker container. (so it would depend on the authority of the service).

However, you wouldn't have a possibility to "log in" to a container or interfere with it in any deep way, because it would break the concept.

I think that the "serverless" concept already treats the running service as an immutable thing so probably adding the proof of running from a specific checkout would be easier there.

throwaway2016a 17 hours ago 0 replies      
While I agree with another commenter that in all likelihood it isn't running the same software but rather the core is opened sourced and they have proprietary value added tools.

For example, many OSS SaaS products I've seen have an open source version that only supports running a single user or single company but their deployed SaaS version is multi tenant.

So if you're really concerned about SaaS products slipping in back doors or something like that that defeats the "publicly audit-able" condition (if I'm reading your concern right) you can't do anything about it except run the OSS code yourself and not use the SaaS.

Social presence is your research keyword. There's a long history of research done which can be pretty much summed up with Cliff Nass's contention that people confuse humans with computers a lot, and transactional status ends up being important because of this.

I think that in practice, VR will not promote empathy for the same reason that social networks have not: because status aggrandizing products will be too popular. You already see this in horror games, where they become literally too scary for VR because the lowering of status in transaction feels too real.

Look up the Proteus effect: that will lead to some detrimental things whenever it gets implemented in the social applications that people will come up with. So there will come new Instagrams, and they will be more terrible than the old social networks.

Yes they could. It's always possible that another company could somehow do search or social networking better than Google and Facebook, find a really clever way of marketing their services and catch on before the former has any chance to catch up.

It'd help if either got much worse at their core business (since that tends to be what dooms a lot of companies nowadays), but even a strong Google could have a competitor that simply offers people a much better and more user friendly service.

But more likely is that they don't die to direct competitors. They die because they become irrelevant. Their 'true' competitor isn't another social network or search engine, it's something that completely replaces the need to have a social network or search engine.

For example, if a company came along and figured out a way to give people results based on what they were thinking about without any direct input required, that could make Google's typical search box and results page and ads completely useless. They'd be like a horse salesman after cars were invented. Same with Facebook.

niftich 2 days ago 0 replies      
What counts as a 'true competitor'? You seem to be asking if there's a chance that someone will upend Google at search, and Facebook at social networking.

But that's not how these companies pay the bills. They built massive ecosystems around their original businesses, and they use that ecosystem to mine data and serve ads. With this money, they've amassed social and infrastructure capital, so they can out-build competitors (Google Drive, Docs), branch out into other product lines (Google Cloud Services), or simply buy them out (Instagram, WhatsApp).

To compete against them, you need differentiation and feature that appeal to a passionate audience. Snapchat, for example, attracts people who've seen or heard how damaging it can be to publically post on Facebook. DuckDuckGo appeals to people who don't want trails of their web searches making it into ads they see on websites. Dropbox works for people because they put out a solid product and aren't trying to force you to be part of a large, monolithic ecosystem.

But it's an uphill battle. Facebook's preferred strategy is to buy out services before they become dangerous (they tried to buy Snapchat back when it was still known mostly for sexting), and Google's is to outbuild others. They form a very effective duopoly in a way.

FB has a "network effect" the value of the network increases with the square of the participants (i.e. the number of connections you can have). Similar effects occur with human languages, telephones, and the internet. It's a kind of natural monopoly, because once one gets big enough, no alternative can catch up. That's why we have the internet, and not internets.

Google is different, because it's easy to switch search engines. One competitive advantage they have is "google suggest" - this takes massive capital investment in server farms to be fast enough, which is difficult for smaller competitors to match.

NOTE: in Google's opinion, FB was a very serious threat (hence google+), because more information about users means better targetted ads. So they don't think they're unassailable.

> If not, then what will cause us to move to a different search engine? What can XYZ make to cause people to leave FB and come to its network?

Three things.

1.The company loses direction, is taken over by less competent management or implodes under its own weight e.g Walmart, GM, Apple.2. Government regulation or public pushback creates conditions for its dissolution. Think Bell, Standard Oil3. New competitors emerge. A giant slayer in this case, may initially not seem like a threat at all and may even operate in a different market space or industry from search or social media eg gaming, VR, IOT. Paul Graham has a good article on this.

Btw, I think FB is dying and that's part of the reason they acquired Whatsapp. It will be obvious in 5 years and they'll be gone in a decade or decade and a half.So is Apple,at least in its current form.

Also you can live without FB but cannot live without google. You can remain days not visiting FB but everyday you will search atleast one time.

I think No for both cases. Default monopolies can go out of favor very quickly, and new technologies can ramp up very quickly.

On Facebook: Remember that Google got the whole world to sign up for Google Plus with their circles. They didn't do anything with it, but it was a clear sign that you can sign up a good portion of the internet.

On Google owning search, if Apple goes downmarket in the phone market, they could crowd Google out of search on the phone. Or there may be some other new paradigm - searching out of apps, with a non-Google choice winning. And if the search algorithm is MUCH better, it could win. Bing doesn't need to be 5% better - it would need to be 500% better.

Yes. When I worked at Google, people were very aware that their market position is not a given and could change any time - eg as people are far less locked in to Google than they used to be to Microsoft in the 1990s. Eric Schmidt used to point to an article from the late 1990s saying "the search wars are over - Yahoo won"...

It wouldn't be easy obviously, but it is conceivable that someone comes up with something that is significantly better than Google/ FB, causing people to switch.

Basically, I believe it will be much harder for a competitor to reach the same capital as Google or Facebook.

Google and Facebook have massive networks, specialized storage strategies, proprietary protocols and hardware, and not to forget the actual data they have acquired. Lots of hard-to-acquire capital.

On the other hand, I do believe that both products could be better. Competitors could have better products, but not for a long time more capital.

You become a recruiter.

Identifying dev talent is one (very important!) part of the job for dev managers, but not enough on its own to be successful.

The only pure application of that skill would be as a recruiter.

That said, you're almost certainly wrong. I can't find the quote/citation right now, but distinctly remember that over a decade of data at Google showed that only one person at the company was really individually exceptional at predicting performance as an interviewer (and he was a special niche case).

> How could I go about proving it to myself...

Much the same way Devs store projects on GitHub-- start building up your portfolio of talent profiles and notes on individuals that you interview & assess. It's a practiced art-- you become exponentially better the more people you evaluate. Also, understand that people do change and grow as they progress throughout their careers. Take the long view and be sure to follow up periodically.

The best executive leaders create a talent pipeline, typically meet & informally interview 2-3 people a month. Incidentally, this builds-up an amazing network of true contacts, which is to say NOT Linkedin contacts. The best primer on this process is Bradford Smart's Topgrading > http://www.goodreads.com/book/show/915182.Topgrading

> then selling this service if I am capable?

Connecting with buyers, in this case Hiring Executives falls into the specialty function of Sales & Business Development. Professional Services firms are always chomping at the bit for rainmakers. If you're serious about this path, take a development course like Miller Heiman > https://www.mhiglobal.com/

Most of the comments I've read here assumes these two things are equal:

How to spot someone that fits in your team is much harder than to spot someone with talent.

Also, as someone pointed out you need to keep track of both hits and misses to assess your skill. I would guess it's easier to track someone if they're successful as opposed to someone who either is not successful or not successful publicly.

Here are my personal options for 2d games, based on my personal background(I developed Flash games):

- Construct2 is you want to create simple games without writing code. Simple to do standard games, hard if you need more control or more complex data structures. It contains exporters for different platform including mobiles(using html5 wrapper to execute html code, based on phonegap or something similar).

- GameMaker - quite similar to Construct2, a bit more powerful and it requires to write more code than Construct2, unfortunately in their own language. You can export games for different platforms(unlike Construct2 it generates and compile the code for each platform in native code) and for html. Each exporter should be brought so it makes this option the most expensive.

- CreateJS - the Adobe Html5 alternative. It recreates the class hierarchy from action3 flash, in html5 js. A tentative to recreate Flash in Html5, good enough. It has the advantage that it can export Flash graphics including vector graphics in an html library which can be used imported in your project.

- Phaser - A nice framework based/inspired/not an exact port of Flixel. It has nice features and it was written only for games so I would say generally it's better than CreateJS, in the same way Flixel was better than plain AS3. It can be combined with Pixi.js to webgl rendering.

- OpenFl - a flash inspired library written in Haxe. The advantage is that it can generate and compile the game in native code for virtually any platform that matters including HTML5. It can even import and use flash objects for graphics.

- LibGDX - write it in java, deploy it on multiple platforms, including html. It uses OpenGl for rendering, for the html export they use Google GWT to translate java code to javascript. It sounded for me as an interesting approach.

My advice is to pick one option and to go for it(the list is far away of being exhaustive). If you have java experience you can check CreateJS or OpenFl, if you want a codeless engine, Construct2 is more popular among html devs than GameMaker.

P.S. It seems Phaser can be easily used with ecma6.

libGDX is a Java game engine that's relatively simple and lets you deploy to HTML5, Android, iOS, and desktop. PlayN.io is fairly similar I think, but I haven't used it.

2048 is actually somewhat of an odd case, since it was originally only an HTML5 game that was built to run in both the browsers of desktop and those of mobile devices. For this reason, the developer didn't actually port the game to Android/iOS until much later. Pretty much all the versions on the App Store/Google Play Store were 3rd party clones of the original, since it was relatively simple and open source.

It entirely depends on yourself and the type of work you can get. If you're an extroverted type, working in consulting may be a good experience. If you're highly creative but introverted type, you may not enjoy dealing with your client as much. If you're service oriented, you'd enjoy working with a client. If you're product oriented, you may prefer working on purely software/tech side of things!

I've worked in both of those situations, but to be completely honest, I believe the variance in experiences introduced by different company cultures, leadership, team members, etc. is so much greater than any systemic effects from the nature of the company's business (e.g. product company vs. consultancy) that it would be pointless and misleading to generalize about one over the other. You can have both product companies and consultancies that will be enjoyable places to work at and it depends much more in the culture and leadership put in place by the decision-makers than whatever is driving the bottom line.

you can use an instance that has docker on it, then setup docker compose files with wordpress, git , apache and setup a port. then on the machine setup virtualhost to point to the entry tcp port of the docker instance. then all you have to do is build the docker instances . You can mantaint all that with git and handle all of your deployments that way.

forge.laravel.com

Even if you're not using Laravel(PHP) it works for quickly spinning up a vps on digital ocean or AWS.

You can setup multiple dev/test sites on one droplet.

Deploy repo via github bitbucket.

It's super fast and easy.

We setup live site on it's own droplet then have another staging droplet. Develop locally with valet/homestead (laravel.com), deploy to staging using forge, deploy to production using forge.

Forge has quick deploy which deploys when you push to your repo.

There is also https://envoyer.io/ for zero downtime deployment.

I would highly recommend using Elastic Beanstalk on AWS. I use the python platform most of the time, but PHP is available as well. If you're a new user, you can get a year on a t2.micro for free, and even if you have to pay that usually works out to about thirty-ish dollars a month which is probably tenable.

I too have felt conflicted about voting one way or the other. It has taken months of research and discussion for me to come to the conclusion that what is best for me in the short run is not what is best for my son and the country in the long term.

The thing that tipped the scales in my decision to vote leave was coming to the conclusion that democracy is the exercise of sovereignty.

The nature Sovereignty is binary, you either have it or you don't, and I felt it is too valuable a thing to give up as it had been paid for by the ultimate sacrifices of previous generations.

I also realised that leaving the EU doesn't preclude trade or special immigration or visa arrangements to be negotiated between the UK and the EU. So while there is the threat that the EU members would want to punish the UK for leaving but they would also be hurting their own economies and since EU economic growth has been low I don't think they would want to do that.

As a Fintech entrepreneur in London a Brexit might hurt new venture prospects in the short run. It will be harder to raise money, possibly harder to recruit and might be harder to grow into Europe.

Having said that, there is nothing to say that it isn't possible to overcome these challenges, for example hiring devs to work remotely from Europe or from anywhere in the world for that matter.

If we end up with worse trade deals and mobility in the event of a Leave - which some rather extensive reading has convinced me is pretty likely (see https://medium.com/im-trying-to-fact-check-brexit , which has been my hobby over the past few weeks) - then that could directly affect me as most of my business is international. Some of my clients are domestic, so that business will almost certainly be affected as the UK's economy slows down or falls into recession.

The international stuff depends on the fine details, of course. Given the pound's likely to take a kicking in both the short and the long term being largely paid in dollars may have its upsides. But overall I'm not going to be at all thrilled if we end up voting Leave.

In case of Brexit I might move my company outside the country (I'm an EU national, not British) and me and my family probably follow suit shortly after. It depends on whether there's visa drama (if there is, then I'll eff off) or the UK remains as part of the free movement of people agreements (like Switzerland or Norway).

It is a shame that fear, lies and racism (which is, again, fear) make people consider leaving the EU, which is the single good thing that happened to Europe since the end of WW2. It is not just about what's the EU (several discussions including some in HN have shown once and again how the EU is completely democratic), but about what the EU could be.

I do respect their sovereignty to choose kicking out EU citizens and requiring them to go through the visa crap, but I can't help but feeling unwanted.

All the reasons to leave the EU seem nave, as almost none of them will change (immigration, adherence to EU regulations, trade agreements, free movement of people) or, even worse, will be forced fed into Britain's mouth without the chance to vote against them.

If I finally have to leave, I wish them all the best as I consider them my friends, but I sincerely prefer to spend my time with friends that appreciate me as much as I appreciate them.

Plus, generally pissing off iOS/OSX software devs doesn't really help sell the platform very well, as some developers have dropped iOS and OSX as a legitimate platform, and develop for Android and/or Windows only.

How much is your time worth? If it takes you $10K of engineering time to roll your own solution, and delays you from shipping your code by a week, is it worthwhile?

That options aren't only "roll your own with open source" or "pay vendors". Have you looked into paying one of the open-source developers for advice, or to do the integration for you, and push changes back upstream? After all, if you think you have to bend it to your needs, then perhaps you don't know how to use it right, or perhaps it's useful feedback where a simple change would help others as well.

I ask because in talking to people, many forget this option even exists. It's as if the idea of paying for open source is a foreign concept.

For ticket management or knowledge bases I would lean toward using open source or paying for a service.

For CRM (or anything else) if it's something unique/valuable to your business where spending some development time would bring value and time savings then go with something custom. It would help if you have a development team that can build it quickly (Rails/Laravel) so the cost/time doesn't get out of control. Building the basics and adding needed features would work well.

For the web, you get a lot more competition because it is a little harder to develop, and there are lots of backends and front ends to pick between. Probably:

Web app- Django/Rails/Restful Node - Sublime, Dev tools in chrome

Simple answer = quit.

If you are only working as a consultant and continue to charge him for development, yet are complaining about an endless circle of changes, not to be rude, but you are as much part of the problem as he is.

If you are unable to quit due to a contract or some other legally bound commitment, I would suggest stopping development and working to convince him to get a third party review. It could be something as simple as a communication breakdown between the two caused by frustrations from the entire situation. Having a third party give their opinion might help settle the matter out.

If you aren't in a contract, and you want to continue to work with him for some reason, you may want to get a contract drawn up that lays out a framework for development and testing. Force him to the timeline and framework.

In the end though, if he is scared to sell there is nothing you can do about it no matter what you try. Sometimes it is just better to cut your losses.

Very nice, you should change the title to "Tattoos by Countries Map".

Re tattoos, I don't know why so many people are doing this too. Sometimes I think it must be a huge misunderstanding: I observe tattooed people longer and more intense because every time I think 'why'. Why did they do this. Often the tattoos are ugly, faded, huge and then I stare even more and longer. And I guess that tattooed people misunderstand my staring and think I am attracted to them and affection must be the reason I watch them. Since many will watch them they must think, wow my tattoo makes people look at me, I need more tattoos.

On the other side they make people look at them and maybe that better than nothing or no attraction and maybe this initial slight disgust could turn into demands the longer you watch because you discover other beauties of the person.
