tsenkov··on Intel and the Danger of Integration
> Intel's problem is that their CPUs were performance focused and as such didn't scale down as well

Don't know the first thing about electronics, but I am interested to learn more about what you meant here. Highly-optimized code (usually) isn't too readable or extendable, are you saying Intel has the same problem with their processor's design?

tsenkov··on Poverty reduces brainpower needed for navigating other areas of life (2013)
I am sure you have given your kids a great example of succeeding in a tough situation and taking care of a family.

Edit: Don't know why was my post down-voted. My intention was only to give emotional support to a fellow human being that goes/went through pain that I personally have struggled with and know all too well.

tsenkov··on Big Trouble at 3nm
Where does the increase in Software expenses for IC Design stem from? https://semiengineering.com/wp-content/uploads/2018/06/nano3...
tsenkov··on Samsung Kicks Off Mass Production of 8 TB NF1 SSDs with PCIe 4 Interface
It may never cost lower to produce in the environment in which both are massively available as manufacturing. But it may happen that manufacturers concentrate on flash storage (could be better profit margins, could be bigger demand from corporations or IAAS operators, could be many other things) and thus, in a cascading way make prices of disks higher for manufacturing, due to limited supply of materials, machines, trained workers for manufacturing of disks.

The only way I see the current status quo to be static by definition is if there is indeed a (above-mentioned) shortage of some raw material that would prevent the switch. Can someone comment on what exactly that shortage would be? Edit: I read the linked post (didn't see this before, sorry). TL;DR - it's just lack of enough manufacturing and issues with building more fabs.

tsenkov··on The US startup is disappearing
If startups fail (test bad ideas) 5x faster than in the 80's and 90's and if most founders quit entrepreneurship after their 1st failure, even if 2x more people are founding companies, then it's probably normal that, overall, less man-years would be spent in startups every year in the US.
tsenkov··on Nvidia Appears To Have A GPU Inventory Problem
Doesn't this only happen when huge preorder(s) get cancelled? Any big players in bitcoin mining bankrupted lately?
tsenkov··on People’s egos get bigger after meditation and yoga, says a new study
Seems like meditation (maybe yoga as well) gives you access to control the Ego. Westerners just want to dial the knob in the opposite direction.

I honestly am more inclined to think that in the world we live in (and the rules we operate according to), having a way to boost your Ego isn't necessarily bad. There is no way you can achieve anything significant (involving many other people), without at least some use for your Ego. Of course you can "crash the ship" if you don't know when to use it.

tsenkov··on Mindfulness Meditation Impairs Task Motivation but Not Performance [pdf]
>Many people have romantic notion of transcendence and enlightement, but when meditation starts to really work they realize that's not what they actually want. Change is scary.

Interesting. Would you care to share an example of this?

tsenkov··on We Should Teach Music History Backwards
I honestly can't imagine how this would work. Even in cinema I rarely like this approach (telling a story backwards). In music history I think it makes sense to go a couple of steps backwards (if you are just a fan trying to better understand their preferences), but if you are really interested - you have to start from the beginning and look how things have developed.

Same thing in programming - starting up with something you can immediately use like JavaScript or Python is a nice thing because it will 'fool' you (in a good sense) that you are now a programmer. (I once knew a successful person who told me "I never start a project I can't fool myself into thinking I can complete within a weekend"). You can only do a couple of iterations back, before it gets too complicated to go backwards.

It's like discovering the usefulness of an integral (Calculus) and then going backwards in order to understand it if you have no prior math knowledge and experience... I often read papers full with math I don't understand and I am forced to go backwards, but it only works because I hit a previous knowledge not so far back in that graph.

tsenkov··on How ARKit 2 works, and why Apple is so focused on AR
Not too many AR apps have succeeded, only because the massively-available AR hardware is not here, yet. The phone with a camera is not it. You can only do that much within that paradigm.

The moment (hopefully it's coming) we have (relatively) normal-looking glasses capable to perform like the Magic Leap's headset (haven't tried it - only judging by the publicly available info and investments), that's when handheld devices become obsolete and that's when we will see AR pick-up and win.

tsenkov··on Survivorship bias and startup hype
Such a nice article. But I have to note that the linked (2013) piece is even better: https://youarenotsosmart.com/2013/05/23/survivorship-bias/
tsenkov··on Ask HN: Is there a new habit you cultivated recently that is really paying off?
I think I share much of your philosophy:

- started exercising regularly in 2013. The sport I choose is Boxing. I haven't done more effective exercise than interval training. And when you learn the technique(s) and get some sparring under your belt, I believe it has quite a positive impact on your confidence.

- In the last couple of years I've been a vegetarian primarily for ethical reasons.

- In that same time I had to learn to better control my weight through diet and calorie counting (sport helped with a lot of it, but vegetarianism makes it harder to get enough protein without going overboard on calories, so I needed to restrain caloric intake). Overall it was a positive change, even though the situation forced it on me, I got down to a healthier weight than before.

- About a month ago I started doing small sessions (10-20min) of transcendental meditation (I would basically calm myself down for a few minutes and then I would repeat a short motivational sentence in my mind). I am way too early into this, but I find the effects to be nothing short of fascinating.

- Few weeks ago I stopped using Facebook, I rarely use twitter anyways and I check email 3 times a day.

One downside of the last one is that I kind of started looking at HN a bit too much. :)

I definitely need to improve my social life and go out a bit more. So thanks for reminding me of that. Cheers!

tsenkov··on DeepMind: First major AI patent filings revealed
That is what I see, as well, with the GENERATING AUDIO USING NEURAL NETWORKS patent application. IANAPL, but I do work in audio software and the application, seems to me, explains a broad model of audio processing using convolutional neural networks (in the claims an input is involved, so I am guessing the title tried to select an even broader set of problems - with & without input).

I think people pointing out that Google defensively files patents may be correct and I hope that's the intention with DeepMind's work, too. I am a fan of the audio work they did with WaveNet since day 1 and was so happy the paper was out for all of us to read. Still, I was hoping I may be able to (read: "daydreaming that I might be capable to") build on it, some day.

Organizations change leadership and they switch focus, too. I believe patents slow-down (even stop) progress and they are quite hypocritical, overall (show me a patented invention that was so unique, the author/owner didn't "stand on the shoulders of" 100's of years of freely available science to derive/discover/invent it and... I will agree for that specific case).

tsenkov··on Developers are manufacturing prefabricated apartment buildings
Interesting points.

I doubt the logistics would make the task of prefabrication not worth doing, though.

The analogy in software that first came to mind was server vs. client-side rendering of websites. (I think much of it holds true for physical construction, too.) This topic seem to reappear every few years (2010 -> everything on the server; 2014 -> everything on the client; 2018 -> everything BACK on the server.) It will likely cycle for at least an iteration more (especially if someone finds a way to advance CPU's vertically, once again), but I believe in future, the consensus will settle to: if you can afford it -> do it on the server. (maybe it already has?)

In the web world, the "builder" would be paying a larger bill, if they would "prefabricate" what they serve to the world, but customers will be happier to get their product/service faster. On the other side - the builder will be able to get to a larger audience with smaller investment into infrastructure, if much of that computation is off-loaded to the clients.

But if we look at the overall cost of those computations - the servers should execute the same amount of computation cheaper (being a dedicated infrastructure for this specific purpose), (generally) it should be in everyone's best interest that computation happens on the server, because overall it costs less for everybody.

Which means that all that it comes down to, would be the question - how critical is this decision, in growing the service/product's customer/user-base and does the RoI make sense (i.e. would that company make more profit getting larger portion of the computation along with a larger userbase, or does it only make sense with lesser server bill)?

So while it would be cheaper, logistically, for facebook to serve their content in a completely raw format (to be fully rendered on the client), would they've still been able to grow their product to what it is right now, if they never made the switch. (I'm speculating about facebook, but I thought it was a safe bet that they do much of the rendering on the server, without confirming that first elsewhere)

tsenkov··on GitLab Ultimate and Gold now free for education and open source
> Github felt safe before, a neutral ground for Google, Microsoft, Apple, Facebook, Netflix, Amazon all come together and share their love for code and just code.

This! This is my primary concern. It's not even a concern per se, since I am convinced all of those companies (except MS of course) will pull-out and disperse to alternative services. And then I believe a 2nd wave of smaller, related-to-products-of-these-companies' projects will also leave.

It was nice to have a neutral ground where all "sharks" came together. But at the same time, I can't blame GitHub's founders and board for searching an exit.

tsenkov··on The Cost of Developers
Sarcasm: 'Overwhelming'
tsenkov··on Ask HN: Any research on 25+h days effects on health?
Totally agreed.

Yet (to continue with the metaphors) telling someone dying of thirst "You should've packed more water." isn't immediately helpful.

Please assume (and that is addressed to everyone who would like to comment) there is no other way, you are in that spot and you need to get that work done. That's what my question is about.

And BTW, I can't speak for other people, but in my case being in these situations where I have more work than I can complete within regular working schedule, is more often caused by me loving my job too much, then me, being forced to work longer hours.

Thanks for the links, will check those out.

tsenkov··on Ask HN: Any research on 25+h days effects on health?
32h awake time is insane. Pun not intended. I finished a 36h stretch yesterday (30h in work) and believe me I know how bad do you feel after this. This is how I realized I can't get more than 10h of sleep, no matter the exhaustion I put myself through. This can't be sustained without serious damage to your nervous system, even for a short period of time.

BTW, he probably did 32 + 16 to keep getting sleep at the same time of the day/night.

Still, that isn't what I am talking about - this guy did not get an extra hour for work. He (metaphorically speaking) just starved himself to death before getting all the food he needs for that same period, all at once. On the 8th day... even all the water in the world is not enough...

Of course getting less sleep then needed, one way or the other, eventually will lead to the same exhaustion. But my question is - which leads there slower, so when we don't have the option and need to put those extra hours of work in - should we be staying awake a bit longer and getting the rest for a 24h day, or is it better to keep the 24h cycle, OR maybe there is no difference at all?

It's "should I shoot myself in the leg or the head" type of question, I know, haha, but while those are the only options, perhaps it's a bit better to aim at those toes? :)

tsenkov··on Ask HN: How did you manage to teach your spouse/partner/half Programming?
Nice!
tsenkov··on Ask HN: How did you manage to teach your spouse/partner/half Programming?
Hm... I forgot about Macro's... Thanks.
tsenkov··on Ask HN: How did you manage to teach your spouse/partner/half Programming?
Yes! Excel was what I thought would be the foothold. I imagined it will be like a gateway grug, haha. She picked it so quick. But nothing past that, unfortunately.
tsenkov··on Ask HN: How did you manage to teach your spouse/partner/half Programming?
Sure we don't have to share passions. And no I haven't forced her or anyone else (other than myself a few times in my life) to do this or anything else. But I am convinced she is missing out on something she will truly appreciate. So I wanted to see how other people communicate their passions in a way to create interest.
tsenkov··on Ask HN: How did you manage to teach your spouse/partner/half Programming?
I tried a variation of the same approach - thought my girlfriend how to use MS Excel formulas and she became better than I am at it in no time, because she managed to apply it in her job. But how to get her to code still eludes me...
tsenkov··on Nvidia and Audi aim to bring a self-driving AI car to market by 2020
I think that's happening already, among engineers at least.

There should be some healthy dose of inspiring "propaganda", but this got out of hand - everybody claims "they have it".

I am so sick of this endless stream of lies, that I'm not even going to read the article. The next thing I am going to read on the topic would read something like "X has a viable self-driving car - it's hitting the market later this year.".

tsenkov··on Ask HN: How do you pitch your B2B product, when no one knows you?
Awesome! Thank you!
tsenkov··on Ask HN: How do you pitch your B2B product, when no one knows you?
Thank you.
tsenkov··on Ask HN: How do you pitch your B2B product, when no one knows you?
Thank you very much for responding. And thanks for sharing these awesome cases.

If you are willing to share - how did you get your first 3 B2B customers?

tsenkov··on Ask HN: How do you pitch your B2B product, when no one knows you?
Thanks so much. For all of this!

You said 6-9 months is a standard time-frame for a corporate sale at F500 level. Shouldn't a new business therefore start with companies that are still smaller and faster at approving expenses?

I am mostly interested in learning how to do #2. I found this which seems to be much on that topic: https://www.linkedin.com/pulse/20141015215831-48424446-the-b... Whatever else you can think of adding on this, it would be very beneficial to the topic (and me personally). How do I get a conversation going? Do you start by giving a general idea about your service? Or maybe you study very thoroughly the company and make an educated guess on the amount of money you will save/make them?

Maybe #7 is a common knowledge to many people, but I find it absolutely brilliant.

Thanks again!

tsenkov··on Ask HN: How do you pitch your B2B product, when no one knows you?
Thanks for replying!

> Focus on talking to those B2B users and convicing them that the product they need is what you are selling.

This sounds very reasonable.

tsenkov··on Old computer ads
Pure gold! I would spend as much time needed to go through all of them.

Few clicks in I found this one: http://www.dvq.com/ads/ncr_321_sa_12_64.jpg

And this is the one that got me searching on the topic (April 1970 commercial of a plotter connecting to a teletype and other sort of terminals): http://www.dvq.com/ads/tsp_dm_4_70.jpg
