Don't use PHP.

As much as I've loved it for many years, in 2011 I can now safely say "Don't use Perl."

Python and ruby are probably both acceptable, though I personally don't like ruby very much. You'd be hard pressed to go wrong using Python, considering the widespread adoption and flexibility inherent in the language.

Oh, and one more time just to be sure you got it: Don't use PHP.

You may not have a proper conception for how anon uses DDOS. A single hacker may DDOS via creating a botnet of zombie computers infected via worm, trojan, or virus. However, anon just uses "LOIC", which is a client that people who want to participate in the DDOS run. There's a call for DDOS of a target, people run their DDOS clients and set the target, there's not necessarily any "hacking" going on whatsoever.

side-question: what does eating meat have to do with thinking you're better than other kinds of creatures?

One explanation: Totally out of touch.

Another explanation: Modern-day web developers are obsessed with branding, and mistakenly think that a clever (read: opaque) name and good logo are just as important as utility value.

This probably started with jwz/Mozilla. Sometimes it works.
First, it's not even close to being "worst of the lot".

Second, there might or might not be a middle ground, but you're not proposing it, Microsoft isn't proposing it and no one else is proposing it. In that context, bringing up non-existent, maybe-or-maybe-not better solution isn't advancing the discussion. In theory everything is possible but in practice WebGL implements a well understood model that has been in use for decades (just like canvas implemented a well understood model for 2D graphics). If we want fast 3D graphics in the browser, and we do, building on top of well understood technology is definitely the way to go (compared to trying to reinvent extremely complex technology that took years to perfect in the currently dominant standards (Direct3D and OpenGL)).

I agree that we must stop legislation that aims to control our freedom and our will. I don't necessarily agree that a P2P DNS system is either necessary nor will it be successfully adopted by the masses, who are exactly the people that need protection from oppression the most.

Rather than treating the symptom (DNS) treat the disease (governments that do not exist for the good of their people).

in 2011 I can now safely say "Don't use Perl."

Really? In the past 18 months I've (very conservatively) doubled my productivity at least twice thanks to improvements in the Perl ecosystem. The only reason I'd tell someone "Don't use Perl" is if I didn't want competition.
Ask HN: How do you manage passwords?
I suspect many of us could improve our handling of passwords for various online services. What is a good approach?
You should be able to get an MVP for less than 50k (there was guy on hn recently who would do it for 5). As others have stated, the language doesn't matter that much and don't worry about scaling (you'll be lucky to have that problem). Your impression of a tech cofounder is off. That person would typically roll up his sleeves and code. Startups require doers, not thinkers.

Microsoft isn't saying that. They completely avoided talking about the trade offs i.e. they didn't even try to weight the benefits of having WebGL vs. the security risks.

The point is that they took a hard line: this technology has potential problems therefore we're not going to implement it.

The point is that they never took this hard line wrt. any other technology implemented in the browser, either standard or of their own making (like ActiveX, BHOs, Silverlight). In fact, as far as I know, they never even publicly mentioned the fact that essentially every new feature you add to a browser comes with a risk of new bugs just by virtue of them being implemented in C.

The point is that they singled out WebGL and made a big, public stink about it when they have never made even a small stink about any other browser technology with similar issues.

The point is that they didn't bother to even hint that they have a proposal for standard web technology that fills the same role as WebGL which strongly suggest that they just want to kill it. After all, who needs it when we have Silverlight 5.

>Haskell compiled apps appear to be memory efficient

Only in extremely contrived and highly tuned examples.

Programming language shootout is not a reality 99.999% of the community of a given language ever experience, and Haskell is a particularly egregious case of this.

Haskell's performance in those benchmarks was a concerted community effort and the prevalence of various unexpected behaviors (such as space leaks) that are subtle and hard to avoid make calling it memory efficient borderline laughable.

I'll go ahead and preempt No True Scotsman responses and say you can spare me using some kind of god-genius programmer as a "standard" for people who are writing Haskell.
Perl is fantastic and I love it.

For a lot of workloads, though, Python is better or equivalent, and probably easier to find devs for.
Yes! How do you handle legitimacy? Why wouldn't we always say its our honeymoon or wedding anniversary to score free perks? I ask because recently I bought a 12 night cruise for our honeymoon, and the cruise agent told us that they had no way to verify and if they gave us preference then all passengers would ask for this. She said it in much nicer words though.

BTW, omni's site claims its a "botique luxuries hotel". Your customer won't know the difference, that's my second point here.

I do think you're onto something though. Gut feeling.

They tested 120 songs found on myspace. One of them later turned out to be a hit, so the researcher went back to his data to see if there was a correlation.

Correlation does not imply causation.

As it happens, there was a correlation. But we don't know what the songs were actually like. (Perhaps the poor songs were incredibly bad, so much so that any musician would have been able to flag them up as likely failures). We don't know much about the 27 participants. We don't know much about the experimental method.

This is not well reported science.

At first I thought 1Password would be slightly helpful, but it's proven itself incredibly useful. All my passwords are complex and different and I have reliable encrypted backups of them.

I agree with Microsoft’s assessment that WebGL is a severe security risk. The gfx driver culture is not the culture of security.

https://twitter.com/ID_AA_Carmack/status/81745430152609793

They are orthogonal technologies, but NaCl is much, much easier to make secure than WebGL, even though it sounds scarier.
Sorry, I'm going to splash some cold water on this situation. Except for senior management and engineering, pretty much everyone is replaceable. As others have suggested, your currently pay will serve as baseline and it's hard to think anoff would be mre than 20 or 30% above that. But I have two tips for you: 1) ask for a review after 6 months at which point you might be able to earn a raise. 2) if this is a tech startup that you think has a lot of potential and stock options are a component of pay, it might be smart to trade a few k in salary for more than a few k in addiional stock.
Can vary a lot depending on the MVP
At work, we use a shared Keepass file (Keepass is a password manager). We are only a small team, so this works out quite well. And this leads us to very secure (and different!) passwords for all our client servers and accounts, because getting and setting passwords is just a click away.

Private, I use a simple system where I have a 'master' password, which I augment with letters and numbers based on the domain name of the service. For example (not my system): A domain has 5 letters and a .com TLD, so I add the number 5 to the end and 'moc.' to the beginning of the master password.
You can easily expand this system for your needs. Works really well for me.
It's ad-words for the music industry.

Which is great, because it means both the little guy and the big guy are on a level playing field. I may be a little band with only a $20 to spend a month on promoting myself, but I can still reach an engaged audience to come to shows.

And like ad-words there's an inherent feedback loop which keeps all parties in check. Fans will only listen if they hear music they like and band will only pay if they have listeners to promote to. The dynamics work out that its in the company's incentive to do the best job they can matching bands with fans.

Bands are like any business, the band is the brand, the song is the advertisement. I've got countless friends who spend all day outside of clubs handing out 10 cent fliers that just end up in the trash. Fan discovery and exposure for a fraction of the cost would be a god send.

Sure it's only going to bring value if the product is good, but that's the nature of the music business. I for one think it's genius.

It's really amazing how poor ebay's user experience is. But the ads are obnoxiously user hostile. Advertising on the Internet is fine but it does not belong on eBay utility pages or competing with sellers' items.
The vast majority of Netflix's DVD contains subtitles, so they are available. There is very little excuse that Netflix has for not having this content available. While "the best" solution from a technical perspective is to figure out a way to add captions to content, the alternative, serving up a "burned in" caption feed for those who need it, is technically possible and easily done.

Of course that costs Netflix money, they have to maintain two copies of each movie. But the law says you have to make the same accommodations available to disabled individuals as others have. Disabled persons shouldn't have to wait until Netflix can find "the efficient" answer, or the best technological solution. It is Netflix's responsibility to make this content accessible, and if today that means two copies of the content, so be it. Such laws are there to protect disabled individuals when it's not the best answer for a company's "bottom line" to accommodate them.

Netflix has been dragging their feet on this, and this is why they will likely lose this case.
Joel hired Pat [1] for the advice and experience that you say is lacking. Pat managed to move the needle on their conversions, which is pretty impressive. So while I've always been amused at the tendency of people to create and fawn over software heroes, I've found his advice very useful over the years.

Edit: obviously the advice and experience in question is fairly narrow and Joel wouldn't hand the keys of FC to Pat, but to solo and micro startups, his advice is gold.

There was a mechanical Turing machine shown at Makers Faire UK. Supposedly it was built only using hand tools and scrap parts. I'd say that's close enough to a hand-built computer.

Only a third of their streams support it, and they have been "working on it" for a long time. Working on it isn't good enough, you need to make the experience accessible to disabled individuals, period. That's the law, and rightly so.

All their DVDs contain subtitle options, so the content is there. They can make the content accessible by providing a separate "burned in" copy of the content with subtitles for those who need it, and they could have done that a long time ago.
It could take years before the block chain is long enough to dissuade a double-spend attempt for a transaction that large, where you have a single party single-handedly accounting for a significant fraction of spending on the network. So for a single $40b transaction, perhaps bitcoin is infeasible (or at least must be combined with traditional mechanisms like reputation, courts, etc.), but for a million independent $40k transactions, they can all be confirmed in a matter of hours for only a few hundred thousand dollars worth of computation, total.

Unfortunately, disabled individuals "voting with their dollar" will likely not be enough of an impact to cause Netflix to alter their business practice. That's why laws to protect minorities exist, because when left to the free market, such minorities cannot exert enough market force to prevent being discriminated against. There are minority groups that we protect against discrimination as a civilized society, and disabled individuals are one such.
"1. A/B testing requires sacrificing some conversions as part of the experiment."
Yes, because it is a net gain if you do it right. If you want 5 signups today instead of 50 in two weeks you're doing it wrong.

"2. A/B testing measures only quantity, not quality."
If you have anything that can quantify your 'quality' of customers then include it in your metrics (I understand this can be hard). If you don't then it is not quantifiable and any analysis of 'quality' won't be based on statistics.

I agree on the other points. Overall I think A/B & multivariate testing is a good approach but can significantly be improved.

It seems like we use it in 'one size chunks' rather than as continuous improvement. Yes we do it ever 'x' days/weeks.
What would be interesting is some kind of machine learning algorithm applied to A/B testing. It has the success metrics, you set a rotation period and it focuses in on the part that works.

You would have to integrate a factor for #5 "Things change" so that the algorithm has the flexibility to adjust to those changes.
As mentioned by others already, the slicehost articles are great for installing and setting up a server (they have detailed guides for Ubuntu, centos, debian, etc.)
A few things to be aware of:

1. Security. I can't stress this enough, as people new to managing their own VPS can end up doing some bad mistakes with respect to security, e.g. leaving root account login enabled, weak firewall etc. Make sure you do a bit of googling to make sure you get a good hang of the security aspects of hosting your sites on your own VPS.

2. Although you mentioned that your sites are low traffic ones, you might still want to choose a light weight webserver like nginx/lighthttpd over Apache, which can be quite heavy weight and need a larger slice.

3. You won't have any mail server by default, which is a free benefit in a shared hosting environment. Setting up and managing your own mail server can be nightmarish.. Look into something like Amazon Simple Email service for that.
It is part of the strategy - and one I have no heart to fight. There is simply no point in listening when the signal-to-noise ratio is too low and your chances of effecting the outcome are minimal.

Yes, expensive energy may do that - but is it the best way to do it? I would have thought that anyone who manages to do those things would probably make money from it regardless of whether the government takes a cut or not.
This lawsuit, and threat of litigation on behalf of disabled individuals, is the only reason why they've been making the relatively quicker process this year. This isn't a cash grab, this is simply the only tool disabled persons have to force Netflix to comply with the law and accommodate them.

I think it would make sense that high number of clicks in the search results plus a low bounce rate would boost your ranking.

If you click on a certain google result, as long as you are logged in, google will boost that result in your search results. The question is whether google boosts it for other people as well.

I'm still pushing for yes. Does anyone have any evidence?

Wow, tough crowd here. When I was in high school, the extent of my computer knowledge was a little visual basic. After watching all of his videos, I'm extremely impressed - it looks like he designed (or at least integrated) a lot of the hardware, operating systems, and applications himself. After a BS and now almost a MS in computer engineering I think I could (...eventually) pull something like this off, but this guy clearly spent a lot of time and effort on learning the ins and outs of computer architecture on his own, in high school no less.

To those complaining that this could be done on a fpga in verilog or something, I think that might be kind of missing the point. There is just something about building the logic up from the ground that is very satisfying. Hooking up the physical wires makes it all that much more real. A huge time investment, but i got the feeling the kid spent a good deal of his free time on it.

So again, mad props. Hope it gets him into a sweet school.

There's a marked contrast between Mozilla's eagerness to press ahead with WebGL and tidy up the problems later, and the abundance of caution it displays when facing NaCl, a technology that threatens its own ricebowl.
