If you really need a rack full of Ruby servers to do the job of a single .NET server, your Ruby programmers are doing something (hint: most probably everything) wrong. Language choice excepted.

Server performance is only very rarely tied to CPU performance. There are a whole lot of factors other than that that impact performance.
Ask HN: Linux Reserved memory for users
Hi there.
As I can run an application with as a specific user, can I reserve an certain amount of memory for the user who's running such application?
If some contiguous memory addresses were reserved and only used by a user, any exploit would only be runnable with it's permissions, right? Or even not runnable since wouldn't be memory reserved to it.

Thanks :)

One of the common strategies for a startup to achieve dominance in a market is:

* figure out how to make network effects important, and
* build a bigger network than your competitors

As YC is essentially a startup in the startup-funding market, it shouldn't come as a surprise to see this happening. As the number of startups YC funds grows, it will become harder and harder for them to keep the quality of their advice high. Without network effects, seed funding companies will eventually reach an equilibrium with each company offering a similar value proposition, and their market share determined primarily by the number and quality of their individual advisors (similar to consultancies). If YC can figure out some kind of systemic competitive advantage, however, they have a chance at dominating the entire market.

I agee. It's also more important that scientists don't involve themselves in politics, especially when politicians are looking to use science as a basis for what essentially is a political decision. When the two get muddled it gets messy. Science can tell us that smoking over the long term can have negative consequences on our health, politics is how we decide what we want to do about it and how. When it comes to the details of 'how', science can provide more insights. However, it's essential that we keep the two separate, just like the separation of church and state. Science does not dictate policy, and it shouldn't.
I'm skeptical about the inbox model.

I use Google Reader for two main reasons. One is that once I subscribe to a feed, I get access to all messages, not just new ones. The second is that I can search old messages as well.

So if I understand Tumblrs inbox model correctly, that's exactly the kind of usage pattern that isn't supported.

I wouldn't even go there.

I worked on an ecommerce project in the early 00's which compiled a high level turing complete DSL (not that far from LISP TBH) to XML and then used a virtual machine written in Java to run the XML. I've never seen a language in which the compiler output was 2 orders of magnitude larger than the source code.

I really don't know how anyone came to the conclusion that any of that was a good idea.

I still have nightmares about that.
Show HN: Looking for fellow "Forever Alone"?
The EU proposed a carbon tax on airlines, which the Chinese disagree with:

http://www.irishtimes.com/newspaper/breaking/2011/1222/break...

EU leaders will be going to the Chinese in a few weeks, cap in hand, looking for the Chinese to help bolster the European bailout fund (otherwise the euro could well be toast). The Chinese are going to use the carbon tax as negotiating leverage. Ah, politics.

Also I read a very interesting article (in the guardian paper i believe) from an insider at one of the major climate change treaties a few years back. The official story was that the different leaders couldn't come to an agreement and that there would be another summit in a few years. The real story was that the Chinese delegation blocked every proposal, thereby sinking the talks (as any major climate change treaty would require the backing of the major industrial powers).
I'm considering using node.js + expresso + couchdb. What worries me is the CPU overhead on the servers for using javascript. How much CPU is needed to run such an app or a service like Trello which I heard is (was?) using node.js. The scalability is a Maserati problem.

It would just like to know how steep is the curve of the required power relative to the number of users for a small messaging app with one database per user (a.k.a. zimbra) ?

The addition of helmets, shoulder pads and downs which evolved rugby into American football meant harder hits and higher likelihood of concussions. Rugby doesn't have these problems because the fast non-stop fluid nature of the game means you can't tackle someone hard enough to cause the same level of damage because you have to be able to get up and run again right away. The stop-start nature of American football promotes tackling someone as hard as they can because you can always recover between plays.
Are you sure generated code is a good thing? Isn't it just support for limited expression power, something you shouldn't be able to get away with in your language of choice that your tools help you with by writing lots of code that are required to express what you intended?

Well-versed may be a very relative term. I've been exposed to physics, engineering and computer science. The physicists had the scientific method drilled in deep. The engineers a bit. The computer scientists had vaguely heard about it. We still call them computer scientists. Your wife may suffer from a similar "relative difference". (Coincidentally, I could repeat your story with my wife, who's a computer scientist working for doctors who work with biologists in a lab.)

'I love you' in 100 languages from Memrise
I've never had any of the hardware in my three Thinkpads fail on me. My Macbook, in the space of three years, had its plastic casing start to flake off, its battery failed, its power adapter failed, its hard drive failed. The other piece of Apple hardware I owned is a TimeCapsule. That lasted a couple of years before it conked out. Luckily this was a known problem and I got a free replacement. I have a friend who went through three iPhones, that all just conked out on him before upgrading to an Android device, which he has had no problems with.

Apple hardware looks good, but it's limited in function, and poor quality.

A Thinkpad keyboard kicks the shit out of a Macbook keyboard. My Thinkpad has a built in smart card reader, gps and a 3g modem. All work flawlessly under Ubuntu. It has both a nipple as well as the trackpad. The nipple on my Thinkpad is much better than the trackpad on my Macbook was.
Two problems — even if it's much unsafer than we think, it's still very safe, and comparisons to other power technologies and the effects of climate change must be made.

Suppose nuclear power is ten or a hundred times more dangerous than we think it is. Then from the figures that have already been quoted show it is ten to a hundred times safer than coal power (in terms of excess deaths from production of energy.)

On the price of failure, the price of failure to deal with climate change in the low-likelihood scenarios is billions dead. In my opinion, any discussion of nuclear power and low likelihood risks requires being put against those numbers, since nuclear is one of the only options to avoid climate change. In contrast to the billions that will die in large-scale climate change, a modern reactor can have an uncontrolled meltdown 2 miles from my house for all I care. It'll be an expensive and annoying mess, but it's not going to kill billions.

What's More Important - Vulnerabilities or Actual Incidents?
Fabulous post. I get tired of folks complaining about 'meetings' when they've never made the effort to hold a good/efficient one.

One additional point I would add is that there really should be someone in the role of Chair (e.g if there are more then 3/4 people taking part). The Chair's only job is to make sure things stick to time and the important points get covered. It doesn't have to be the 'boss', even though people expect it to be.

I used to chair lots of meetings and while my style used to come across as a bit militant, after a few sessions people could be assured of the following. (1) Timing was followed (i.e start and end on time). (2) If someone was specifically asked to be there, it was because their input was needed. (3) There was always an agenda and we'd stick to it.

Although I felt like a bully at first, people did seem to appreciate this style after a while. Folks would arrive (on time), discuss/decide stuff quickly and then get on with their lives.

Meetings are just something else you have to learn about if you want to do them well.
Because not all Linux distributions follow Linux Standard Base. It would be silly for (to use an example) Arch to have a lsb-release file when it's very method is anything but LSB. So os-release gives a unified file regardless of the distro methodology. In fact this file could easily be extended beyond Linux to any Unix-like OS - which lsb-release would be less practical for.

IP is an artificial market rather than !market.

Also, data is non rivalrous, unlike a stadium. Basically an unlimited number of people can access it.

OTOH, charging something might put the onus of paying for the collection a bit closer to the users, if that group of users is small and well-defined. It wouldn't be fair for them to reap large benefits at the expense of everyone else.

That said, though, if the users are a large and not well-defined group, opening up the data is probably more beneficial.

> And it brings up all manner of ethical grey areas: is blogging journalism?

I believe the crux of the problem is that 'influential bloggers' want all the credibility of journalists ("we're writing and reporting on things!"), without any of the responsibility ("we're just blogging our opinions!").

This is what leads to situations like below:

Then there's the post in December where MG [...] thought he'd uncovered some kind of huge conspiracy when he accused Google's Android chief, Andy Rubin, of deleting a tweet. A few days later Siegler had to recant (sans apology, of course) when it turned out that, um, nope, Rubin hadn’t done that. Of course there’s a simple way to avoid bonehead moves like this — you do the reporting before you publish the accusation, not after.
I don't see how this is a problem. Every cell has a copy of every post--that should make it possible to search it and get all older posts as well.
It reminded me of your evaporative cooling essay. http://lesswrong.com/lw/lr/evaporative_cooling_of_group_beli...

Perhaps communities that are quick to kick out oddballs/trolls may reduce noise and distraction. However, by eliminating dissent and criticism, even invalid dissent, this newyorker article suggests that the community also might be harming creativity of comments by remaining members. Eventually creativity becomes so low that the forum members get fed up with the monotony and leave, and the forum dies?

A hundred terrible ideas would drown out a few good ideas, but a positive number of horribly wrong or even offensive ideas might be optimal for generating the most good ideas.
Yeah, but he's an...intellectual.
That's all fine and dandy but after time, people tend to stop inviting you if you are assertive and only invite people who will blindly support their ideas.
scientists are in the end only humans and have their own believes, failings and political agendas. The whole system of peer reviewing and the acknowledgement that every scientific theory can be falsified is a testament to this realization.

I fully agree with the first part, but care to explain how "believes, failing and political agendas" relates to the concept of falsifiability?
Being prepared for a meeting means the meeting should never take place at all.

If you know what you're going to say, put it in a damned email. If I have a question, I'll reply. Then you can craft a thoughtful and correct answer as time allows while consulting any necessary reference material, instead of talking out of your ass.

You also look cool by violating the laws of physics. People don't have to actually attend a "meeting" to be there, they just have to gasp read their email! Amazing!
I don't think that essay says what you described. There was a bureaucracy before the US - how did the British, French, and Spanish Empires run without a bureaucracy? And of course the Chinese bureaucracy was established long before the Americas were settled by Europeans.

It looks more like it's saying the US started with a distrust of bureaucracy, which it inherited from experience with the European empires, which caused us to "hobble" our bureaucracy, which were therefore less effectual, which lead to continuing distrust.

Was it taken because YOU took it? It doesn't make sense.

Later you refer to the fact that the message said it shared the same email address. Couldn't you sign into the PRO account , change the email address, and log into your defdac2 account?

This. Also, getting grants is for a large part doing politics as well.
The way I read it, it's more of a social interaction phenomenon than whether ideas are inherently good or bad.

Something about knowing that people in the group disagree with some idea that's presented, and the reasons why they disagree, might be more important for improving your creativity than your own isolated assessment that an idea you heard is wrong.
While Clojure remains my favorite JVM language, I think Kotlin is the first language to have a fighting chance at replacing Java as an industry-wide blue-collar language. It doesn't try to solve programming's problems with new approaches like Clojure and Erlang; on the contrary - it's meant to let programmers continue thinking more or less as they have been thinking so far, but it has all the modern features and a good balance of power vs. ease of use/learning. It's what Java was 17 years ago.

What did you do to get Scoble to do an interview with you? Just a friendly email to him?
What strikes me about this list is how it basically renames stuff that already exists. I'm about to sound like I'm about 60, but please, bear with me.

Every meeting should have a clearly defined mission statement ... I hesitate to recommend having an "agenda" and "agenda items" because the word agenda implies a giant, tedious bulleted list of things to cover.

Yet an agenda is the best tool for controlling meetings if the chair is any good. It says "this is what we will discuss and decide and only this". A meeting should not be a free-form discussion -- leave that for chance encounters in the office kitchen. It's a transactional form of communication, a tool to make efficiently make collective decisions.

Do your homework before the meeting.

Which is why agenda are circulated -- and even more because:

Make it optional.

Yes! And as Tom DeMarco points out in (I believe) The Deadline, meetings which don't stick to the agenda lead inevitably to everyone having to come to every single meeting just in case something gets decided. If the agenda is trustworthy, people will stay away who should stay away; only interested parties -- who will do the homework because it's relevant to them -- will turn up.

Summarize to-dos at the end of the meeting.

These are called "minutes". Properly written minutes are very useful and they don't have to be in legalese. The University Computer Club at the University of Western Australia, where I studied, have excellent minutes[1], written with a sense of humour.

Before I came to my senses, I used to be involved in student politics. And if that unpleasant experience taught me anything, it was the power of meeting mechanics. A well-run meeting is an extremely useful institution. Get in, discuss, decide, get out. Bam. No ambiguity, nothing left hanging.

As a chair there is one rule that counts: don't let the meeting get side-tracked. Stick to the agenda, work it. People quickly learn that they need to get their stuff onto the agenda in advance and the whole process begins to work better. Discussions become more focused, decisions can be made quickly and efficiently.

Those who are interested might like to join an organisation like Toastmasters or the Penguin Club to hone their skills, or get involved in committee work, or join a union, incorporated club or political branch. The skills of running an effective meeting are very useful. I applied them during my capstone unit at uni; my team delivered 92% of agreed functionality on-time with no significant defects. And part of that was running tight meetings.

As mentioned in that man page, the /etc/lsb-release file only contains details on what version of the LSB the distribution conforms to (if the distribution isn't LSB-compliant, the file shouldn't exist). It doesn't have the version of the distribution itself, which lsb_release finds in distribution-specific locations.
Are Niche ecommerce sites an easy way to make money online?
One of the points nearly covered in the article is not going off track, as soon as people get comfortable and start discussing things off topic then the meeting is over as it is no longer productive.

The ethos of standing meetings is pretty good, nobody can get comfortable and decisions are made quickly. To this end meetings ARE useful in some situations, topic for discussion should be circulated prior and agreement made in the meeting. As you don't want to fall into the trap of long email threads between co-workers which could be solved with a few minutes of discussion.
I feel like we see the same things with languages as we had with version control. For a long time, you had only CVS, then you had (too) many options to choose from: monotone, darcs, mercurial, git, and I certainly forgot some.

Now, we see new languages appear (and get some exposure) at a frightening pace: Rust, Go for system programming, and on the JVM: XTend, Ceylon, Kotlin, Clojure, Scala, Groovy, etc

It's great to see things move, but when you have so many option, it can be hard to make a choice. I expect some of these to take the lead, like git seems to be doing in the DVCS space.
