Ask HN: How many startups have you started?
Why did they succeed? Why did they fail?
Maybe because not everyone is a software developer in the first world, or they aren't making $75k a year, or they have other unavoidable costs (kids,parents,etc)
Absolutely. Nothing in the natural universe moves that fast anymore.
Sorry if this information is visible somewhere: Which dialect of regexp does RegExr "do?"

In the past, when I've looked for a good Internet RegEx test site, I've had trouble finding one that "does" the Java dialect.
That strikes me much more as a policy to retain employees and stop competitors getting access to that wealth of experience more than anything else. I imagine someone whose been working for a telco (especially in Mexico where technology probably isn't cutting edge in many places) for 30 years is very valuable to the business, so stopping them leaving is important.
If it's slower both in and out what's the benefit?

To guy below me: Ah, thanks. I thought the guy above was trying to say it's slower than paging to disk. : )
Using Stunnel to access certificated SSL endpoints over HTTP
We have dedicated servers in colo. I'm upgrading to new SSDs on a server-by-server basis, as I have the opportunity to do so. This one just hasn't been upgraded yet. That wasn't really the question, though. Whether writes take 30 seconds or .1 seconds, if I don't care, I think there should be an obvious path to make it take a millisecond by letting it just "commit" to RAM and then return.

Which, it seems like there is in the innodb_flush_log_at_trx_commit option, which is awesome, and which I'm trying out, now.

Yes, and that causes so many problems. As you indicate, all of science is easily biased by what has been done and what has been published in the past.

Negative results are essential for a complete understanding of science and when they are repressed, complete access to the globally available data set is not available.

If I'm an ethically-dubious pharma or lobby group, I love this situation. I keep funding testing until someone comes up with a positive result by chance or p-value hacking - then fanfare that result all the way to the media and to the bank. (Negative results don't need to be seen)

If I'm a cynical scientist, I take the money and p-value hack until I get the results my funding body wants, so that I have access to more money in their next round of funding. Now I'm far more successful than a completely honest scientist.

In fact, the honest scientist will either seek to replicate what the cynical scientist did, or leave the profession.
rackspace, onmetal-memory[1]: 512 GB, $1650/mo (3.22 $/gb/mo)

softlayer, dual Xeon 2000 Series: 512GB, $1,823.00/mo (3.56 $/gb/mo)

these are on-demand prices. pre-pay, or use a term discount, and its cheaper.

Build it yourself: You can build a Dell or similar on a 2-Xeon-proc (E5 series), your main limit is getting good prices on 16x 32GB DIMMS. But lets say you can buy the RAM for ~$6500, then its just dependent on the rest of your kit, lets say $10,000 flat for the whole server. $277.77/mo over 36 months, but you still need network infrastructure, and you might want a new one in 12 months, but you get the general idea.

So how does this improve on existing IM, say: XMPP?
Yes, due to Pumped Hydro's benefits... the major cost is the size of the generators.

A single 100MW turbine can store weeks-and-weeks of power if drawing from any small lake. But for it to be useful to a lot of people, you probably need to build a gigawatt scale turbine.

With that said, the Bath County generator is the largest in the world, and is close to 30 GW-hr of capacity (3GW of power. Yes, it can empty the lake in 10 hours, and refill it in another 10 hours)
I heard a few years back (no source) that when they model traffic they can design systems that work perfectly, its human error (not hitting the gas fast enough after a green light, changing lanes to often, 18 wheelers getting in the far left lane to turn right) that make the models break down.
Your confidence and shameless curiosity will take you far in life, with exponentially compounding returns.
RAM is cheaper than people.
Excellent clarification, thank you.
> So you're saying, I gotta spend 2% of my financial existence on a stinkin telephone?

I choose to think of it as spending 2% of my financial existence on an internet browser, a world-wide atlas, a communication device that I use to connect to five various methods of communication, an e-mail client, an entertainment system (games, video, podcasts, music).

But I guess I'd be making the same argument if this was about cars, and not smartphones.
When I did my traineeship at ATLAS DAQ around 10 years ago, one issue was how to per-process the data that could be considered invalid fast enough, to be able to throw it away before it arrived into the cluster.
Improve Your Productivity with the Noisli Chrome Extension
I'd advise that you launch with a minimal set of features and get people on the platform and make additions to it as you go. There is a saying, you should be at least slightly embarrassed by your version 1. Can't remember who said it, but man it so works, it also is a great motivator to improve.

I personally don't believe in stealth mode without some very special circumstances, and this wouldn't be one of them. The times I would say stealth is good is for serial founders that have credibility to raise money privately and keep the wraps on something until it launches. And even then, they likely have some large clients committed already and are already on a solid path.

So my 2 cents, don't quit your day job. Launch the site, get some traction, get feedback, don't hide it, promote promote promote. Once you have some traction and have people talking a little about it, then you can start to think about a pitch deck and trying to raise money (if that is your goal). Although there is "easy" money as some say, it isn't that easy really, you still have to have fundamentals in place or have a track record proving you can do it. If you get a little traction though, it isn't unrealistic to have a small group or a high net worth person provide you some seed capital to try and accelerate the pace.

Personally, I wouldn't go the raise money route initially, I'd first start off trying to make money with the platform. Bootstrap it, see what happens. The go big or go home attitude isn't necessarily wrong, but the majority of businesses are not launched or founded that way. They start small and build up. Nothings stops those businesses from being as large as a VC backed business (though money does equal velocity), and you can always attract money at a later date, usually under more favorable terms.
If you ever feel like writing a paper on this I can highly suggest Ludwik Fleck as a starting point (his writing on thought collectives).

Why IoT Needs 5G
Why Transparency Is Not the Key to Content Marketing Success
This reminds me of the opening to David Foster Wallace's "This is Water."

There are these two young fish swimming along, and they happen to meet an older fish swimming the other way, who nods at them and says, “Morning, boys, how's the water?” And the two young fish swim on for a bit, and then eventually one of them looks over at the other and goes,
“What the hell is water?”

Of course the invention of representations like written language, equations, and graphs changed the way people think. It's just hard to see at first because you've grown up immersed in them.
>> We are not our work, we are what we are indipendently of our work.

I don't know, I don't think it's necessarily wrong to "be your work." I'm sure a surgeon of a certain congenial disposition can be his work and it is a healthy thing. I'd hope teachers were wanting to "be" their work, though I also understand that they often don't get paid enough to do so.

I also don't want to tell anyone their particular lifestyle choices are "wrong". If you want to be a recluse and, IDK, collect stamps the rest of your life, if that is what you really get enjoyment from, more power to you. Just as long as you personally know what that is and that you're not going to become mayor of your home town because of it.

But you are right, by default one shouldn't "be" their work. It's a privilege to have a job that you love. Most of us don't have that privilege. We have to make our own way, and there's only a limited amount of time to do it. Don't get distracted with things that ultimately aren't that important to you.

Weigh the options, make an informed decision. People need to stop deluding themselves into thinking they can do everything. We can certainly do anything, just not all of it. You have to choose.

We are moving to SSD. It just takes a while. This is the last of our servers to not have SSD. But, nonetheless, it seems obvious that for many use cases, one should be able to say, "I don't care if it's on disk immediately. Just be fast."
Because it's so much faster than having to go to disk.

> The experience of Firefox and Chrome is that long release cycles actually decrease quality, precisely because of the dynamic on display here: long release cycles create huge pressure to land under-done features just before a deadline. With date-driven short release cycles, if you're not confident in your feature you'll be happy to just slip it to the next release. It greatly reduces stress on developers in general.

This comment really resonates with me, and wasn't something I thought of -- the pressure to deliver when your release cycle is so infrequent is something I hadn't noticed before but once mentioned, realize it's absolutely true.

I have only one Nexus device. A 7 (flo, the 'newer' one). I migrated that to CM quite some time ago.

Google OTAs are now block-based, as far as I understand. Which means that I cannot change my system and apply the update afterwards.

I have no problems of that sort with CM. So, while Nexus devices might be a good base line, I personally would still move away from official Google releases.

That said, I agree that the experience is quite nice and it sure helps to get timely updates.
Graphene Composites Go Big
Putting Our Data Privacy Principles into Action (Firefox' ads)
If performance is a problem with a 1.4GB database, your system is either extremely low end, or you have some seriously un-optimised queries or database architecture and/or should take a long hard look at what caching you are not doing that you should be (including in the form of materialised views)

It simply is not your overall disk IO capacity that is the performance problem with a dataset that small. At least not for a CMS.
Postgres's default settings are pretty bad. You'll want to increase shared_buffers to somewhere between 25%-40% of your available system RAM (if you're using 9.2 or earlier, you'll probably need to update SHMMAX using sysctl) instead of the default 128MB.

For the thing you described, you probably also want synchronous_commit=off. That means you might lose some commits in the case of a crash, but you won't get data corruption from it, and writes will be much faster.
SSD prices are about as high as HDDs have traditionally been. The difference is now the bottom is falling out of the HDD market and you can get 3-5 2TB HDDs for as much as a 256GB SSD. So lots of devices and appliances use a single SSD for read- and write-caching, backed by a bank of high-capacity HDDs.
You're assuming there are people competent of building such systems who are ignorant of the fact they can earn that money anywhere in the world.
Wow, I haven't seen that. As you can see, my link goes straight to cern; you appear to have found someone else's meta-dashboard.

Why is moving examples from the bottom to the top better?

So that's your argument in defence of a new command line tool? Oh, the irony.

Also, how many of those non-cli users actually know enough programming so as to write raw JavaScript on the cli?

This is something I will need to consider shortly (off-grid build in the next year or two), I have much research to do on this first. I didn't realize Well Witchers were still used, I thought there was some scientific method and Well Witchers/Dowsers had been relegated to history - fascinating.
They couldn't legally, no, as data protection laws still apply, and every proposal I've seen includes very strong language about how specific and pertinent the intel must be in order to be shared.

But they could illegally, just like anyone could illegally take your car, or charge up your credit card, or any of the other numerous things that are physically possible but illegal.

> The speed of the particle (0.999 999 999 999 999 999 999 9951c), if it was a proton, is so high that it would experience relativistic time dilation by a factor of about 320 billion. At that rate, the particle could have traveled for the entire duration of the universe's existence while experiencing less than sixteen days subjective time.

These aren't good comparisons. Dev studios work out promotional deals for this tech. This tech isn't just free, they're being paid to put them in games. We saw them do this with Physx and probably with these other technologies.

In my driving experience in the US:

If a highway has two lanes, the average speed in the left lane is higher than the average speed in the right, but the only major passing opportunities are on the right when there's an empty stretch (because no one merges right).

If a highway has >2 lanes, the left is never consistently the fastest moving lane, and almost every passing opportunity comes from moving right. It is not uncommon to find the right lane near empty, and it is then possible to blow by everyone in that lane.

The exception to the above is in areas with heavy merging, wherein the average American driver seems to not understand how to merge (either blocking one another, or coming to a stop as the merge lane begins). In this case, speed seems to increase moving left.
I wish people in America would be taught this

I remember being taught this when I started driving in the 90's. And I remember people following it until the mid/late 2000's. It's as if a switch was flipped, and nobody cared about this practice anymore.
Fair enough :)

If you try the value 2 please write here if it's better for you. It can be a good compromise: "only an operating system crash or a power outage can erase the last second of transactions." It still doesn't "flush" so I guess it can work really good.

In most cases it's probably better to have one machine each for different jobs, then all cpu on every machine can be used for the current job. There are probably very few jobs that take extreme amount of cpu without also using a lot of data which would have to be moved around a cluster anyway.
>Eric Schmidt doesn’t care if I’m using Emacs

Actually, yes he does especially if you use GNU/Linux because that runs the world. The importance of free/open source is so great that if the popular libraries switched to a proprietary license a lot of companies would go bankrupt paying the license fees.
>also outside Silicon Valley you can have tremendous wage insecurity

Oh, puleeez. I doubt you meant it so broadly, but this comes across as having a very insular view of the tech landscape. There's really no "wage insecurity" for a decent engineer in NYC, DC area, Seattle, Boston, Raleigh-Durham, etc. etc. either (sorry if I left your awesome tech hub out..).

If anyone finds themselves in a 20h/day situation and can't find a local alternative, then you'll need to move or find a remote gig. 140h/week might happen for short sprints, but if it's sustained then you're a fool for staying.
Atlanta has rolled out variable speed limits on some highways (I285) which attempt to slow down the flow BEFORE people reach the congested area.

I'm not sure how well most users understand how it's supposed to help them go faster by slowing down; a bit more education could be helpful so everyone plays the game.

It is a bit weird seeing the speed limit jump from 45 to 65 then to 35 within the space of a mile…

I'm an admitted phone-hopper, and while my preferred platform is Windows Phone, I've had to give that up for Android so I don't have to carry two devices. I've had everything from basic phones up through flagships, and I've found the best battery life and balance of features/price to be (unsurprisingly) in the mid-range.

I was using a Nexus 4 for a while, but when my wife's phone died I gave her that and got a 2014 Moto G. So far I'm very happy with it, especially given I only paid $150 for it with no contract. It's not quite as snappy as the Nexus 4 was, but the screen is a bit nicer, the battery lasts a bit longer (usually at ~60% when I put it on the charger before bed), and the camera is definitely better. It has a few quirks, things I've seen on many Motorola phones (the earpiece doubles as a loudspeaker, and it randomly switches volume during a call; the ambient light sensor sometimes stops working so I end up with an extremely bright screen at night). But overall I feel I've gotten my money's worth and then some.

I do miss my Lumia 925, and I'm looking forward to sampling whatever Windows 10 Mobile devices come out over the next year. But I'm more than satisfied with my budget phone.
Hmmm. You're writing this as if being a stay-at-home mom is pure bliss. It's not. It is completely wonderful to spend a lot of time with your children. But it also has a huge cost in adult self-actualization and development. Some of that is completely silly (the way our culture values people who work more than those who don't, or who are experts at projecting a sense of workplace-type competence). But some is completely legit: striving and succeeding in the adult work world can also be rewarding and exciting. From our experience, looking after a kid leaves very little time for hobbies.

That finances thing is a pain... same situation here :-)

Take a look at this option on MySQL innodb. I've used this in the past to radically improve speed:

"If the value of innodb_flush_log_at_trx_commit is 0, the log buffer is written out to the log file once per second and the flush to disk operation is performed on the log file, but nothing is done at a transaction commit. When the value is 1, the log buffer is written out to the log file at each transaction commit and the flush to disk operation is performed on the log file. When the value is 2, the log buffer is written out to the file at each commit, but the flush to disk operation is not performed on it. However, the flushing on the log file takes place once per second also when the value is 2. Note that the once-per-second flushing is not 100% guaranteed to happen every second, due to process scheduling issues."

Apparently I'm useless at touch typing.

I can barely break 15 words per minute on this thing without making mistakes after 30 minutes versus 86 wpm using my normal style, which involves me using my index and middle fingers and occasionally looking at the keyboard.

I'm confused about why 'net metering exists' is a good argument against these batteries. As I understand it this is a mandated buy of excess home-generated solar at retail prices - is this correct? If so, does everyone really think this is sustainable if rooftop solar really takes off? Even if it technically is I expect to see widespread lobbying to end it (like in Hawaii) and expect most of the lobbying to succeed.

I don't think the Tesla batteries are a good way to lower your home energy costs, but I don't think I would factor in net metering as a reason why, at least not looking 5-10 years out.
AWS, because we make a lot of use of S3 - last I looked there weren't any alternatives that truly rival it. Largely then end up using EC2 for cost (data transfer in-data centre) and billing simplicity.
