There is no generalized way to access the free space of a mounted and mutable file system.

What you'd be better off doing on Unix type OSes is creating a large empty file, deleting it but keeping the file handle, and reading/writing that. That's a traditional way to make a self erasing scratch file.

It doesn't work on Windows, though, because Windows won't let you delete a file that's open.
I used to take piracetam 800 mg daily, apparently a low dose. I now take noopept, 20 mg daily.

Possibly. The Go 1.1 scheduler is inspired by Java's fork/join scheduler, which suffered from the same problem in Java 7. In Java 8 it's been improved to no longer have a single wait-list, and external submissions of tasks (i.e. tasks that are not submitted by tasks running in the thread pool, but elsewhere) are multiplexed randomly (IIRC) among the individual thread queues.
Amazon Kindle Fire HD 2: Exclusive details on new Kindle Fire tablets
The bill in question was drafted not by some fire breathing, bible thumping, tough on crime, law and order conservative; but by Patrick Leahy, who is considered to be one of the most liberal or progressive of Senators.

If even the most progressive members of Congress are openly advocating a decrease in government accountability and trying to weaken the powers of citizen opposition to a totalitarian surveillance state, then any hope that Congress will try to stop the slide towards totalitarianism is misplaced.

The Executive branch is obviously leading the charge in favor of totalitarianism, and the Judicial branch has mostly condoned or defended increased government power at the expense of human rights and civil liberties, with a few notable slaps on the wrist here and there. Mostly, however, the Supreme Court has tended to simply deny lawsuits seeking to challenge torture, infinite imprisonment, spying, and war (or to just say the plaintifs don't have standing to sue in the first place).

So the Legislative, Executive, and Judicial branches are lost. They are not likely to change for the better any time soon. If anything, there will likely be a move towards even more extreme concentrations of power and abuses of human rights and an increase in surveillance as the Republicans take back Congress and the Presidency -- especially if there's another major terrorist attack.

What can be done?
Yes. Floats/doubles can be strictly ordered. Now, instead of storing a value as a float, store the distance (in your strictly ordered list) from the previous value. This is effectivly mapping your floats/doubles to ints; but it works because the mapping maintains the ordering that is central to PForDelta.
tool already capable of doing it is socat.
ex: socat -v -x - tcp:google.com:80

Starting with the obvious, the USSR and China were/are two of the largest experiments in socialism/planned economies. The USSR failed pretty spectacularly, while China's communistic policies are continually losing out to the spread of capitalism within it's own borders.

Meanwhile, in Europe, some of the more socialistic countries (Greece, for example) are failing economically while a strongly capitalistic (comparatively) Germany is continually having to bail them out.

I really don't see any argument that supports your claims, though I'd like to point out the answer is not pure socialism or pure capitalism. It's a happy medium, the million dollar question is exactly where that medium resides.

I'd argue the big thing that made HTML so easy to play with was permissiveness, not the lack of explicit compilation.

Perl doesn't tend to have an explicit compilation step. You could write a HTML compiler to be as permissive as HTML parsers and you wouldn't have the same frustration you had trying to get started with perl.
I have a few internal sites in production that run on IIS with FastCGI (using https://github.com/antoinemartin/django-windows-tools).
Do you really use all those databases?
Agreed - this is great work and I'm really happy to see Government moving in this direction. Key point for Federal leadership here (in addition to the cost savings) are that a small team of developers and designers working together using open source tools can build great products that scale to meet the demands of government. Helps that the team seems very capable!

It's a risk for any CIO / CTO to kick off a project like this in government, and I applaud HHS for taking the step.
I too switched to Moba recently after trying just about everything else. Some of the things I really like about it over the competitors:

* single binary installer

* X server

* Tabs

* Automatic SFTP sidebar when connecting via SSH

* painless SSH-tunneling (I can never remember the order of arguments on the command line)

* dancing Tuxes

There's probably more things I haven't even discovered yet (which may be too much for some people, who just want a simple terminal emulator). It's not all roses, it has locked up a couple times on me, but thanks to tmux it doesn't bother me much.
If you know that you need to be grouping by dates... then it's usually best to store the date fragments in a separate column so you can take advantage of indexes.

The project is pretty cool, but I don't think it's worth adding the dependency lock-in for the functions.

Simply, if you know ahead of time that you want GROUP BY date, then you should create a new column for each interval. `week`, `day`, `hour`.

That way you will have fast queries...

How many of the <fixnum> benefits of TDD and unit tests are achievable through the use of sufficiently advanced type systems? Disclaimer: I'm not using advanced type systems to replace unit tests myself, but the more I read about them the more I suspect that most of the tests I've ever worked with (a small sample to be sure) could be obviated by pushing the logic they test for into structured types.

> I didn't think judges qualified as "inferior officers", which is a term in the appointments clause with some meaning. Am I wrong?

I think the construction of Article II Sec. 2 and Article III Sec. 1 admit of no other non-strained reading than that Supreme Court justices must be appointed through advise and consent and other Article III judges are appointed through advise and consent in the absence of specific alternate provision, but may be appointed by other means provided that the mechanism is consistent with the Article II Sec. 2 provision regarding inferior officers and the Article III Sec. 1 provision that Article III judges have tenure in the judiciary in good behavior.

> What other judge is appointed as an "inferior officer" outside of advise and consent process?

Historically, both the Emergency Court of Appeals (1942-1961) and the Temporary Emergency Court of Appeals (1971-1993) were Article III courts whose members were drawn from the among the active members of the federal bench and were appointed to the specific court in addition to their prior appointment outside the advice and consent process (the Article III status of the former is explicitly called out by the Supreme Court in Lockerty v. Phillips.) This is the same model used for the FISC and FISCR.

The best thing the RISD president ever created
I think it's fair to argue that a company's purpose is best illustrated by its revenue streams. Reasonable people can disagree depending on the circumstances.
Personally, I find this line of argumentation nothing more than pure ad hominem. This is an open specification, open to review by everyone. If there were technological changes made to somehow support better data collection, people would be able to see that.

The IETF and the W3C has always had large companies involved in specs, often with their own agendas, I see no reason to attack Google in this way.
Interestingly, they're using the same technique for the cloud effect as that Japanese energy drink site that was posted here not too long ago.
Yes, I consider the site to be a little disingenuous. I actually did a disingenuous thing myself, and watched the site owner queue up posts one time at a conference, and it was a mad dash of anything interesting and about 100 tabs stacked, popped, and restacked.

Now, it could be a cool site with links, but the astounding overhead of all of the JS and crud that comes with the site, and the dubious opportunistic way in which it operates is pretty tough for me.

There are some ties to people like Jer Thorp who also manages to somehow mention his own Twitter handle in tweets as if it might get lost out there that he indeed tweeted whatever it was, anyway, it gets very tedious to watch the the rolling wave of new people that get suckered in to the scheme. Some seem to pick up on what is going on and move on eventually.

I wish I could articulate better ways to call out these kinds of abuses but they're so subtle, and the echo chamber so new to the thing themselves, that it is hard to get the message through.

Thanks for this. After reading the article I was able to go to the design document and keep my head above water. Go has a lot going for it, but one underrated aspect is excellent propagation of information about the language. The talks by the likes of Rob Pike and the writing here and elsewhere drives the language in popularity and productivity. We learn the language, true, but we also learn very strong computer science. No wonder people become more productive when they switch to Go! By using it and reading about it, they get better at programming! (I'll grant that this is true of learning new languages in general, but maintain it's especially true with Go...)
That's not exactly true... in Erlang, any binary with size > 64 bytes will not be copied. Instead a pointer to a shared memory area will be passed.
I take Nootropil, 3200mg daily to help combat hypoxia damage from a bad habit I picked up about 20 years ago (smoking =). I can't say there are any noticeable effects of doing so that I wouldn't call placebo effects.

I used to take a much larger, and more structured regimen, and found it very difficult to keep everything balanced, some things increased the consumption of ACH so much that I had to start taking choline supplements, but if I screwed up my timing/doses, I'd hit nasty lows from too much choline intake. I gave up on it, as the only noticeable difference I had from the regimen was a more difficult job of timing, having to have a lot of pills around, etc.

I stick with nootropil due to its well-established safety, and minimal impact on overall chemical balance.

Google is the industry's most active and effective corporate advocate for TLS. They're one of the key drivers for certificate pinning and one of the earliest mainstream deployers of forward secrecy. So I think that argument is a little bogus.

You don't need that if you use postgresql:

It's worse than that, actually, as ASCII from the start¹ included provisions for variants for non-English latin characters and alternate currency symbols, and ASCII was essentially the same project as ECMA-6² (ECMA being the European Computer Manufacturers' Association³, a standardization group founded in 1961).

ASCII as we know it (which is essentially the 1967 version⁴) like the corresponding ECMA standard⁵ provided for overloading punctuation characters as diacritics ("/¨ ^/ˆ ~/˜ '/´ ‘/` ,/¸) to be overstruck in typewriter fashion; ECMA-35⁶ (1971⁷) defines further extension techniques using control and/or escape sequences.

So, yes, it's just a failed attempt at an anti-American cheap shot from someone who isn't familiar with the development of character set encodings.

First, to call Google an advertising company makes no sense. It's a tech company. You don't call a newspaper an advertising company either.

Second, there were people involved in designing this, not just an anonymous corporation. You can actually see their names in the proposals. It's a good design, that's why it has been adopted.
I concur. While the article made sense and the decisions seemed logical, I'm shy of the level of knowledge necessary to come up with healthy criticism. A nice quantitative benchmark would clear things up an awful lot.

You provide the reason in your second paragraph. The reason for dumping is to gain market share. Once a suitable amount of market share has been reached then prices will rise to profitability.

I don't believe the technology moves fast enough in this regard to resist the effects of dumping. Any new innovation that the Germans could introduce that would lower their costs enough that would allow them lower prices than the Chinese dumping would almost certainly be available to the Chinese. Who would then lower their prices yet again.

You do have the right idea about free markets correcting itself, in most cases. But a truly free market would result in all the German companies going out of business with the result being almost all panels coming from China. That would be bad for Germany but good for China. The reason to get in there to regulate that is because, under a truly free market, it would be possible for one region to totally decimate another region's economy due to numerous social and economic differences between the regions.

Think of locusts. They fly to a crop, eat everything, and fly away. Good for the locusts but bad for the farmer.

Show HN: My Product Landing Page for SMS Marketing
Hi All.

I realize that SMS marketing is a crowded field, however, I believe there are still some opportunities with the right product. With that being said, I wanted to test the interest before building the product with a landing page.

As this is my first Show HN, would love to hear some feedback as to what changes may be needed, what works, what doesn't work. Since there's no product yet, there's no screenshots I can show so its more about the messaging and gauging interest.

I've reached out to 2000+ local businesses whose revenue is driven by foot traffic by postal mail and going to test adwords.
