That may also be a result of how Erasmus programs are structured. At least here in Czech Republic, Erasmus students tend to take classes taught in English, not classes taken by local students, so they interact with many other exchange students but not with locals.
Start with statistics. Seriously, just google time series modeling (this seems ok for a beginner https://www.analyticsvidhya.com/blog/2015/12/complete-tutori...). Learn ARMA/ARIMA/etc.

Don't worry that just because it isn't using deep nets that it isn't state of the art or won't get the job done well. That would be like thinking python's built-in sort function isn't sufficient because it doesn't use Spark.

I used to just read all the posts into a big hash, but when you have 1200+ the RAM usage started to get too high. That's when I started sticking them into an SQLite database.

Even if you remove the database post-build, such that each post must be re-parsed and re-added, the reduction of RAM meant things were still very fast on my desktop.

Upvote 1000x - I'm sick of hearing people who've done nothing and "thought leaders" ranting on. I'm pleased I put my head down, did work and did something that worked for me that I can encourage others with and give evidence. I wish those who have done nothing would go away - and stop filling my inbox, and targeted advertising spots, and meetups with their crap. I wish I could help others see over the shouting and point to what does work instead of seeing them fall for the hype every time.
But then there's no such thing as an unannotated program. I'm confident in my ability to prove things the old-fashioned way, using brain, pencil and paper, so I don't see much value in merely having my proofs verified by a machine. If the machine can't contribute to the effort of actually coming up with the proof, it should stay out of the way.
An ironic thing to say in a seed accelerator-owned website.
You somehow make it unclear whether or not Linus not being a multi-billionaire is a good or a bad thing.

Are you saying that because he didn't try to monetize his code as much as he could have, it somehow makes his opinion less valuable?

The man created Linux AND git, it doesn't matter whether or not he's got billions. He's got something more important than that, a legacy.

>> That revelation hit most people like a ton of bricks.

That seems a bit naive considering how fast technology improves.

Another pet peeve of mine: how can people possibly not be more worried about the kind of data collection happening at the tech behemoths? I can imagine about a 100 different ways they can by themselves, or by collusion with other powerful companies, completely suppress and eliminate serious competition. (And if all else fails, of course eventually buy them off plus their principles - such as what happened with WhatsApp).

Nominally at least, organizations such as the NSA will probably have a few people who are conflicted about stated purpose of the organization vs actual behavior (e.g. Snowden). There are no such checks and balances for corporate entities, except for this notion of competition, which is now acknowledged to be ineffective in the winner take all high tech ecosystem. The absence of any input from employees in these forums around, for e.g. Windows 10's heavy handed updates, or Facebook's extraordinary chutzpah in attempting to triangulate every piece of information they can to a person in their database, is quite telling.

Think of the FB experiment which was trying to manipulate people's emotions. Why aren't Mark Z and co being investigated for crime? [1] No legal precedents? - perhaps it is time to create some. At the very least, it will expose their data collection practices to the world and make similar companies more wary of taking people for granted.

> Swarm is an effort by Docker to extend the existing Docker API to make a cluster of machines look like a single Docker API

This isn't really true any more; it's a reference to the original version of Swarm. The version of Swarm that came with Docker 1.12 is completely rethought and not constrained in the same way.
These trends are either evolutionary or entirely predictable. Several so predictable that they first made their debut in movies long before most of us were born.

I think this is what he means. Working on any of these ideas doesn't make you an innovator. You might do something in a slightly better or more novel way, but we aren't inventing crap.

And if you don't execute on your slightly better path, you'll still be beat by someone with a slightly worse idea who buckled down and delivered.

Silicon Valley is littered with companies with better ideas and better base products that lost.

> Why do I know his stance on guns if the thing he does that I have interest in is creating software?

Well, I don't know. But if I had to guess, I'd say the three most obvious avenues would be that you looked at his personal site, where he quite reasonably talks about his interests other than software; or that you looked at his personal blog, which mentions four topics in the tagline and only one of them is software; or that someone else brought them up in a context where they weren't relevant. Two of these are appropriate places for him to talk about guns, and one is no fault of his.

I'm not saying he doesn't inject arguments about guns in inappropriate places. But the fact that you know his stance about guns doesn't mean he does.
I like stuff like this :)

Did you consider automating it at all though? I've been considering using Companies House data, and a web-scraper, to find tech companies in my local area.
Ask HN: Response Time vs. Conversion Rates?
Hello HN!

I am frequently asked to provide some financial justification around doing certain things to improve response time of web applications, especially in the e-commerce space.

I usually end up building a model based on response time vs conversion rate, showing how the reduction (or increase) of the first is causing a change to the latter.

I base the estimates on the three different models:

a) Amazon, where a 100ms increase in latency has a 1% hit on revenues [0]
b) Google, where a 0.5 seconds increase in latency decreases traffic by 20% [1]
c) Walmart, where a 1 second reduction in the response time causes a 2% increase in conversion rates and for every 100ms they grow incremental revenues by 1% [2]

All those numbers have been circulating from multiple sources and shown in a number of presentations, but they're all fairly dated (some of them are from 2006!).

If you do, how do you handle this task? Do you have more recent statistics to base models on?

Thank you!

Agreed, but if Python is your main weapon of choice, one will usually want to invest next in something really fast to bridge the gap. I wasn't aware Racket is that much faster....I'd like to see some benchmarks.
Nice. I'm wondering how often NVidia's solution makes a mistake. Also, the paper says:

> More work is needed to improve the robustness of the network, to find methods to verify the robustness, and to improve visualization of the network-internal processing steps.

But it doesn't hint at how this would be approached.

Also, how they arrived at the particular network topology seems sort of a mystery.
As others have also expressed, foremost I'm also sorry about your son's diagnosis. As a parent of very young children, I live in fear of getting the news you received, as does my wife whom I might describe as a "Vaccine Skeptic".

Everyone says that so-called "anti-vaxxers" can't be pursuaded by reason. You're on HN so you must have some attraction to reason, and here two people responded with exactly the study you asked for.

I'm curious whether "everyone" is correct that you are not at all pursuaded by this evidence, as well as the evidence presented elsewhere against Wakefield?

My wife had a doctor once assure her when my eldest was getting her MMR something to the effect of "our shots are safe because we don't use the preservative that can cause autism," and now she's scared stiff of vaccines and requires my assurances that all data points to that doctor saying a lot of nonsense, probably with good intentions. My wife doesn't know how to read scientific studies or to distinguish between a sample size of 12 or 90,000, so it falls on me to provide the not-so-reassuring fact that our children will or will not be diagnosed with autism based on factors that are, at this point, not within our control, and that avoiding vaccines is only comtributing a net-negative to our children's health (and the health of our community). But again, my wife also doesn't frequent sites like HN as you do.

I like to think that we shouldn't give up on the idea of trying to find the proven truth about worries like vaccine-autism links, and spread that beyond our usual insular sphere of people who already agree with us. I appreciate that you're willing to share your (obviously unpopular-here, given the downblvoted) beliefs on HN. But I also hope that everyone's efforts to provide factual, scientifically valid data points about the very real lack of any vaccine-autism connection is not for naught. Is my hope at all justified, or is "everyone" else right?
Best option would be to rent a dedicated server and put all your side projects there until one of them catches on and you need to scale.

You can get a small dedicated server for $30-40 per month. If you rent it yearly you will often get a discount.

FDE's and Yubikeys are nice and good controls for some classes of risk, but distributing your passwords onto dev laptops via a git repo. opens you up to a wide range of risks that those won't help you with.

Unless you got super-corporate lockdown with the end point devices you have risks like "A user with access to the repo. installs software which turns out to be malware", "A user with access to the repo. leaves their laptop in a coffee shop unlocked", "A user with access to the repo. puts it on a USB key and loses the key". None of these are nation state level concerns, they're things that could impact the project purely by accident, or at the hands of low-skill attackers

The point is once you've allowed secrets to be in a distributed system like this you have very little control over what happens to them, which is why I'd recommend using a secrets management system where there's more control (e.g. vault from hashicorp) in almost all circumstances.
I'm surprised drinking culture hasn't been mentioned more here. As an American who when to an American university, I had no friends who were non-American. When I reflect on the reason for this, I do remember meeting students from other countries but they had different priorities than myself and my group of friends at the time so we never really clicked. (our priority was to go out and drink as often as possible - 4 days per week usually) For someone coming from a country where alcohol is consumed in moderation from young ages, I can see how this would be an unappealing scene to get into.
Facebook: Take the Work Out of Hiring
> He's got something more important than that, a legacy.

Why is that important?
If a company hires you at SF HQ and you live in SF, then a year later you announce you're moving to Seattle, it is entirely unfair to ask an employer to float your travel expenses back to HQ.

Your choice to leave, your financial burden. Sure, you can negotiate this as if it were a raise, but be advised that most companies will then simply deny your request to move.

Sure, not every word adds value, but the same could be said of code.

> Torvalds said he subscribes to the view that successful projects are 99 per cent perspiration, and one per cent innovation

Certainly true. IMHO, innovation is about orientation, while perspiration is about walking. They live in different timescales: GTD takes time while innovation is a spark. However, both are equally important: it would be useless to go forward in a wrong direction, it would be useless to identify a meaningful direction without going forward, and it would be of course useless to walk backward.

An acceptable - and subjective ! - balance is hard to find, these days.
Of course we don't - and it's rather disingenuous to say we do.

We want to promote diversity where we can, and if you walked into our office today you'd be surprised at the balance we've got.

My statement was highlighting what the current state of tech is, and to make a more gender diverse working space i would have to sacrifice quality / skills / talent, which I will not do.

But if I am not willing to sacrifice, how am I supposed to have a more diverse space?
The adage "we stand on the shoulders of giants" comes to mind. Some of the louder people in our industry could stand to remember this.

Oh, companies house is a good one. I would have a look, but I would be wary as I can see traps; for instance the legal office address registered at Companies House might not be the actual office address you should go to for an event or an interview.

That's really interesting, thanks for taking the time to share. I had no idea GABA's function in the brain 'inverts' at birth. When you say this could show up in brain scans, do you mean to say it has, or it's a theoretical (in the scientific sense of the word) explanation ?

I remember reading in 'The Brain the Changes Itself' that brain scan studies have observed that the brains of people with ASD do not differentiate between different auditory frequencies well. The way it is described in the book is that as infants develop, the part of the brain that processes sound starts to more selectively 'light up' as we 'learn' different frequencies, like someone becoming more precise when playing a single note on a piano-keyboard. However, it was apparently observed that the entire 'keyboard' lights up for people with ASD, regardless of the (audible) frequency.

I've always wondered about this. The author put forward an interesting theory about sensory over-stimulation in ASD sufferers, but it sounded kinda speculative to me. Did you come across this in your research? And if you did, do you think there's anything to?
Random access by filename was fast, since we used a hashing mechanism to locate the directory quickly. But (what I meant with "browsing") was slow backup and slow inspection using normal shell tools.
The OpenBSD folk have a similar (and surprisingly polite) motto of "Put up or hack up" which I've always been fond of.
3d printer bubble continuing to slowly convert itself into a large pile of plastic spaghetti.

There are still some people who haven't heard that they aren't terribly useful in the end, unless you are the kind of people who like to make things, tinker, etc and have a vague idea of making prototypes and so on.

Once the normal human has printed his third Yoda's head the interests vanes pretty quickly...

Disclaimer: I built a few printers myself, worked for 3DS and spent man-months staring at plastic spaghetti.
Eh, that's quite a stretch. I guess people that always were logical thinker can pull it off, while people that were not can't learn it even at 14, 18 or 23.

I'm sorry, but your understanding of Masters degrees seem to be dangerously misinformed. There is a wide spectrum of MS degrees offered by US universities, from leading-to-PhD to Professional-degree-for-Software-Devs. I agree there are some who "flunk out" their quals and leave with a Masters, but the selection process for a PhD is stringent enough that this is a very small minority of all MS degrees.

Personally, a research oriented MS degree allowed me to work closely with a researcher and contribute to that research leading to paper publications and a thesis. The goal of the program seems to have been to allow people to get a taste of doing research and then move on to a PhD program if they found that appealing.
.NET came with massive additional resource consumption, with its very own comprehensive system API and with an entirely different resource management paradigm.

Adding it to an average C++ program back in 2000 would have been utter madness and I don't think it was ever what Microsoft intended as the standard use case for .NET.

Also, C++/CLI is not the language in which most people want to write .NET software, nor is it C++. It introduces an entirely new pointer syntax just to deal with resources that don't work with RAII. Its very existence proves that there is a huge gap to bridge.

You simply cannot smoothly and efficiently use a library written in a language that comes with a tracing GC from another language/runtime. That's why we have all those isolated library ecosystems for Java, JavaScript, .NET, etc.

Microsoft already had exactly the right technology to build on back in 2000. COM was a simple idea that would have stood the test of time as the basis for multiple language runtimes that can share a library ecosystem efficiently.

But they decided to ape Java and balkanize their OS APIs. Now they are busy undoing the catastrophic damage they did to Win32. It's a huge mess, nothing ever sticks, nothing is ever coherent enough to be blievable, trust in their APIs has been eroded so much it hardly exists at all any more.

Not to rain on anyone's parade, but it would also be useful (probably more useful) to see stories of older people who have tried and failed to become developers.

It's nice to see the success stories but I'm always wary of survivorship bias. If there are ten people who couldn't make a go of it for every one of these stories, it puts a different view on things.

I tend to think of Racket as an alternative to Python, rather than a complement to it. C and Rust fit better the latter description.

Racket is faster than CPython, but that isn't anywhere near the top of my list of reasons to use Racket instead of Python. When speed is a priority, Rust and MLton (Standard ML) are both much faster than Racket. But:

(0) Racket is much more malleable than either Rust or SML. Rather than bash your head trying to model your problem domain in the existing language, you can redefine the language until it's the ideal tool for your problem domain.

(1) Unlike other languages that also advertise malleability (Common Lisp, Smalltalk, etc.), Racket is malleable in principled ways, so you can define abstractions without figuratively stomping on abstractions defined by other people (which you might also be interested in using).
No, things would be better if someone (not me, alas, with a nod to the Linus rant) would design, build and market a wifi chip with FOSS firmware.
