It was conversion from standard MongoDB to RocksDB based MongoDB, so replica count calculations don't really apply.

And yes, Mongo did not optimize for space efficiency, which is why there're efforts to optimize for space efficiency.

Just like there were efforts to optimize InnoDB for space efficiency, that stalled and got derailed by these hole punching ideas.

InnoDB did not become shit, it just stalled and did not progress in an area where lots of innovation is happening elsewhere (and there were possible avenues for optimization), so it may become less relevant.

As the post [title] said, InnoDB lost its advantage.

P.S. I wrote the original post.

I don't think this sentence is true:

> Most of Earth’s internal heat was delivered by the giant collisions that built the planet, a large portion of which remains locked inside its crust.

In 19th century, Lord Kelvin estimated the age of Earth using this method, arriving at somewhere between 20 and 400 million years[1], much shorter than 4.6 billion years currently accepted. It turns out radioactive decay keeps the Earth's inside warm for a much longer time. (I.e., assuming Kelvin's calculation was correct, without radioactivity the Earth's core would have frozen over within the first 400M years.)

Correct, just like with the Commodore 64, the CPU clock actually differed based on the graphics hardware output, which was back in the day adjusted for the household CRT TV sets.

The master clock crystal oscillator on the motherboard was set to be 2 clock cycles per pixel and other chips clocks were derived from that.

Hence the CPU was set to 1/4th of master clock, so the European PAL[1] machines (a 50fps TV standard) actually ran slightly slower than the American NTSC[2] machines (a 60fps TV standard with a smaller vertical resolution).

> Also, you'd want to require a TPM and a trusted computing platform to prevent recovery of the wallet key.

This is the part where you're going to run into problems. If the software can access the wallet key, then so can the hosting provider. If it can't, then how is it going to spend money? (Hint: look at the operations that a TPM actually provides; do they actually map in a useful way to things a Bitcoin agent would actually need to do?)
Is it fixed now? You posted 35 minutes ago but the last bot message is from 10 minutes ago.

The only way to deal with the unstructured nature of the "Who is hiring" posts is to have some sort of schema that can be processed. I also wanted to do something similar (imagine it with dc.js, for example!), but the data is too diverse.

A sample entry could be:

company: 'Some Company',
jobs: [
{
dev_type: 'Web/Mobile/Data',
dev_sub_type: 'Frontend/Backend/DevOps/Android/iOS',
visa: 'Required/Not required/Transfer only/Sponsored',
remote: 'Yes/No/Maybe'
locations: [
'SF',
'London',
...
]
},
...
]

All posts could have a METADATA: compressed_json entry that can be processed by the site and displayed/filtered accordingly. Perhaps it could be built manually at the beginning until it catches up.

Here's a negative fact: you gleefully lie via deceitful equivocation.
Data Science and Big Data Explained for the Non-Data Scientist
I'm not an expert on trusted computing, but I thought that TPMs can enforce secure boot and encrypt data that cannot be recovered if unauthorized software is running on the system. There are probably vulnerabilities in the implementation, but I thought that, in theory, it's airtight.
I wish I could upvote this comment a million times. I see the same kind of ignorance-of-their-options (note I specifically say ignorance-of-their-options; I'm not saying anyone is generally ignorant) reflected when developers complain that it's hard to get under the hood of Windows or when developers complain about the tooling on Windows. You'd at least hope that this segment of the user-base would have more intellectual curiosity sometimes.

From the software developer angle, Windows is a FANTASTIC system when you need to get down to the nuts and bolts. People really need to educate themselves about the registry and the various ways the OS can be tweaked; as well as the various tools available (at a bare minimum those from Sysinternals).

Some other examples - the extensible kernel-level instrumentation that you get from ETW; the excellent crash and hang analysis tools provided by the likes of WinDbg (supported by the excellent debugging support in the Windows kernel -- yes, you can enable a keyboard shortcut that will memory dump your machine if it's hung and then it's a few commands to see what crashed); the commandline environment provided by PowerShell (I haven't used it much but really need to get into it more). Not to mention Application Verfier.

I could keep going on and on but it'd probably cloud my point if I haven't done so already :)

Not saying it's perfect or the be-all-and-end-all either; I also use all three major OSs, though primarily develop .NET software on Windows. Just frustrating that many of the complaints can be boiled down to "Windows doesn't work just like Linux/Unix does".
All these strategies are interesting, but I'm afraid we are over-engineering the problem here. The pretty simplistic strategy I'm using now is basically just pattern matching, and so far I had only 4 misplaced posts out of the 840 for April alone: that is < 0.5%. And it's blazing fast! I can rebuild the entire db in less then 30 seconds.

Given these number I believe pretty much everything more complicated than that would be a total overkill... Good food for thoughts though!
I almost totally agree with your overall view, but you could have made the same point whilst still being civil about it...

No, there shouldn't be any rouge planets moving fast enough. Stars at our distance from the galactic center move at roughly 230 km/s, with relative speeds of 10-30 km/s. The escape velocity from the galaxy is ~550 km/s, which is something like 0.2% light speed. Very few objects get accelerated above this speed, and when they do they leave the galaxy (so the probability that we pass one going by is negligible).

Dear all,

We would like to hand out a big thanks to intrbiz from the IRC channel #suse on the freenode IRC network, for his great support in helping us getting our server properly recovered again.
We are sorry for the inconvenience caused in the mean time, but hope you will enjoy the final work.
My 11 year old son did not want me to get him a story book. Instead he wanted a programming book, so we bought "Hello Python" by Anthony Briggs from a bookstore. The Amazon reviews for it ended up not so good, so we'll see how it goes: http://www.amazon.com/Hello-Python-Anthony-S-Briggs/dp/19351...

Anyway, I've recently read (my Kindle list):

* Curious Myths of the Middles Ages by S. Baring-Gould
* American Gods by Neil Gaiman
* Instrumentalities of the Night series by Glen Cook
* The Dragon Never Sleeps by Glen Cook
* Many HP Lovecraft stories which I hadn't already read (I bought HP Lovecraft Complete Fiction)
* Grimm's Fairy Tales
* Cookery and Dining in Imperial Rome by Apicius
* Takeshi Kovacs series by Richard K. Morgan
* A Fire in the Sun (Budayeen series) by George Alec Effinger
* Wool Omnibus by Hugh Howey
* Hunted (Iron Druid Chronicles) by Kevin Hearne
* Catspaw by Joan D. Vinge

Also I've been watching videos more than reading recently:

* Peaky Blinders
* Top Gear
* Skins
* Grimm (where everyone in Portland lives in restored craftsman style homes and uses devices from Apple)
* The Grand Budapest Hotel
* Constantine
* Moby Dick (Patrick Stewart version)
This is a cool idea, I've backed it and I want a packet!
Could you imagine being that lifeform that cored through the kilometres of ice to finally find an empty space with starlight shining down on you? Alone in a void, the closest celestial being is 10 light years away. Fission could power you for a long time, but rather than looking at the planet as a place fixed, the species could begin to think about where to go. As a planet. They may question whether life on a planet orbiting a sun is even possible (wouldn't it be too hot to form an ice layer?!) but where else could they head?

Fascinating.

Nice timing. I just finished installing dragonfly on vultr (http://www.vultr.com/?ref=6828113 (aff link)), following this guide: http://hostingformula.net/how-to-install-dragonflybsd-in-vps...

The only painful parts were:
- realizing I needed to go manually unmount the iso in the vultr control panel, since rebooting would otherwise just take me back to the live cd.
- needing to host the iso somewhere so I could point vultr at it, not particularly hard, but annoying even for someone like me who's already used to configuring nginx.

I hope more people give dragonfly a chance, hammer seems to me the way filesystems should be. If you just want to try it out, there's a coupon code for $20 dollars of credit floating around for vultr.

Lincoln's relationship with slavery "evolved" during the war. In 1860 the Republican party platform promised that they were only opposed to the expansion of slavery, they did not propose to end it. In the early stages of the war Lincoln reiterated his modest goals with respect to slavery in order to try to keep slave states in the union (this partially worked) and to broker a quick end to the rebellion.

With the Emancipation Proclamation Lincoln made his cause explicitly anti-slavery, and in the 1864 election the Republican platform explicitly included the complete abolition of slavery.

For the rebels, the preservation of slavery was always the primary cause for the rebellion. The fact that a Republican could become president -- even one on a limited platform -- was proof enough to them that slavery was not safe from political reform as long as they remained in the union.

For a brilliant account of the relationship between slavery and rebellion I recommend The Fall of the House of Dixie by Bruce Levine:

Germany perhaps, but not Japan. With Germany it is difficult to say since the post-war split of Germany is something that doesn't have a great analogue in Reconstruction. Japan did not have a porous border with the US, and although there was nevertheless a large amount of cultural exchange following the war, it was nothing compared to what occurred between the North and South in the US. Furthermore, while American individuals involved themselves with Japan's government following the war, that was not general American voting public doing it; it was only a handful of people. Having a MacArthur from the conquering nation and having to share a government with the conquering nation are rather dissimilar. The Japanese public were not voting for American leaders, and the American public were not voting for Japanese leaders. American and Japanese leaders were not regularly engaging in debate, nor were they forced to reconcile differences in their domestic policies.

However I would not consider either of those a modern US invasion/occupation anyway. We don't really fight/invade/occupy like that anymore.
Piercing the corporate veil is not a trivial task. Generally speaking, this only happens when a corporation owes taxes (in the US). But, the point of setting up a corporation is to shield the owners from risk associated with the operation of the corporation.

No... it's Amazon ML and Azure ML trying to catch up with BigML. They copied many things from our service but forgot to copy the ease of use. Services like Azure ML, Amazon ML and even Google Predict API work like a black box, and lock your model away, making you extremely dependent on their proprietary service. With BigML, you can easily export your models and use them anywhere for free. If the goal is to democratize machine learning, then the ability to extract your models and use them as you see fit is essential, and only BigML offers that level of freedom.
Using tests for an "objective measure" is doomed on its face. That's gigantic sign that the people involved are more interested in blame transfer than in progress.

You can use tests for trends. That's a good use of tests. You can use tests for feedback to the individuals directly involved. That's also a good use of tests.

This corresponds to my "software metrics" points. If I suddenly see an uptick in average lines of code committed, I should take a look. If I start seeing a big increase in bugs filed, I should take a look and see what just happened. Most of the time, there's a good explanation. Sometimes, someone is doing something stupid and I need to go fix that. And, rarely, someone is doing something malicious and needs to be fired.

Tests should be used as an indicator to a human to "look here!" However, test results are simply an indicator to a human to exercise judgment--not an objective measure to remove humans from the loop.

The problem with education is that people really don't want to use the tests as "indicators". As in the article I pointed out, that particular school now is having a decrease in results--the tests are indicating with a big, red klaxon that something is going wrong. People should be examining the situation with a magnifying glass to figure out the issues and fix them.

The problem is that "something going wrong" is very clear--a new principal and new directives from the head bureaucrats. Do you think that they will look at the test results and say "Oh, we need to undo these policies and get a new principal?" Unlikely.

Would you like a metric that only ever gets used against you but that your management gets to ignore? Of course not. It's why the complaints by programmers about management are legion.

And that's why teachers hate all this stuff. Somehow, it only ever gets used against the teachers. When the evidence points at the administrators, school board or politicians, it gets ignored.

This isn't even limited to teachers. Physicians oppose the collection of this kind of data about outcomes for the sames reasons--it will very quickly get turned into a ranking system that gets used against doctors rather than for improving outcomes.

Rx is not very comparable to Esterel, which is more about event-oriented programming than the classical meaning of "reactive" (today reactive somehow is taken to mean data flow but...that wasn't the case in the 80s).

FWIW, my wifi had similar problems on 10.9. Not every time, but occasionally when it goes to sleep, it doesn't wake up and you have to reset the whole TCP/IP stack to make it work. And lockups after wakeup requiring hard boot are not unheard of either. So it may not be exclusive for 10.10.
That depends on what you're talking about.

Near term, AI will be the legal responsibility of its creator. It won't matter if it functions independently after being turned on. It's actually a very non-complex thing, and not very different from what we're already looking at. This type of AI is little different than the software programs we're already running; if someone owns it, they own it and everything it produces (absolutely no different than Google owning its crawlers).

If you mean the assumed futuristic, independent AI that is fully conscious - well that's a very long ways into the future. A lot of things will change once a guy in a garage can spin up a new conscious life form and unleash it into the digital world. There will be an immense number of laws limiting the creation of new AI of this variety. That said, the creator will still bear responsibility for this futuristic AI's actions.

AI will be legally split into two segments: non-sentient / non-conscious, and sentient / conscious. The latter will have at least a magnitude more regulations (in most countries) limiting who is allowed to create it, what it's allowed to be capable of, where it can go, etc.
In principle, yes, if you know that the TPM's private key hasn't been compromised. At a minimum, you would need some way to verify that it's actually a tamper-resistant hardware chip, and not a software emulation.

7.16 MHz (NTSC) / 7.09 MHz (PAL), and what's worse, average instruction takes about 8 clock cycles. Fastest ones take 4 cycles. "move" (like mov on x86) takes from 4 up to 36 cycles depending on addressing modes. Multiplication is up to 70 cycles. Divide up to 140 cycles (unsigned) and 158 (signed).

In some sense it's really like a 1.7 MHz machine. And that's being generous.

> I sometimes think that if Congress hadn't pissed all over the Constitution's federalist design in the 1960's, we'd still have segregation today.

I don't, but only because, at best, I see the actions of Congress as a lagging indicator of societal will. That enough people in society demanded Congress act enough to force them into action enough to piss all over federalism is indicative that society had already come along and made its point. Had there not been enough people wanting it, Congress wouldn't have acted.

I mean, unless we take it as a given that the CRA's biggest aim (by the government) was really a ploy to grab additional power at the expense of the Commerce Clause.

I think, the reason why it is enduringly popular is that the designs are not just aesthetic, they are also intertwined with developments in technology, industry and the economy. 'Modern' design is essentially 'throw out all previous ideas, start with a blank piece of paper, and remake things using modern industrial methods and materials'. That isn't just a design or a fashion, it is the embracing of a new reality.
