To speed up ssh login time, try adding the following to your ~/.ssh/config: Host * ControlMaster auto ControlPath ~/.ssh/auth/%r@%h:%p ControlPersist yes For me this changes connection times from 1.7 seconds to 0.189 seco

It launches it in app mode (no tabs, no URL bar). I'm not sure if that's the same thing as launching the FB app. In windows you copy the chrome shortcut and then edit the shortcut to add the command-line arguments. Then you add the shortc

For me a lot of it feels like noise. Back when I was in charge of security at a payment processor I was subscribed to all the relevant mailing lists (as required by the PCI DSS). Now that I'm working with something less valuable I just re

This is easy to do with chrome. I have many different profiles, all of which are completely separate. Just launch with the --user-data-dir argument: #!/bin/bash exec chromium-browser --user-data-dir=/home/jewel/.profiles/fa

If by kernel you mean linux, then yes, it does do precisely that. Try this out on a large file: time cat bigfile > /dev/null time cat bigfire > /dev/null Then wait a few minutes and try again. Linux won't evict the page

The other feature that should be worth touting is that you don't need to install anything special on the source repository. I think it has potential. The problem space is complex enough that many different solutions can exist. For example

Here are a couple of random suggestions: 1) Try the pomodoro technique, or some other form of time tracking. When you're about to take a side path which may or may not be a distraction, you can decide how long it'd be worth investing in it

Is there any reason you couldn't keep an offline copy of the environment in the browser by using http://bellard.org/jslinux/ ? It takes a while to boot, but if you saved the RAM to local storage then it should resume instantly. You'd have

It seems like it'd be possible to automate gem testing for this scenario. Take the 1000 most popular gems, run the tests that come with the gem in 1.9.3. Run the tests again with the RC and see if any that succeed with the stable version

I was hoping for details about how it was accomplished in such a short time, but the article mentions nothing but "special magic sauce". There are obviously complex ways of accomplishing this, but here's how I've managed to pull off fast se

It's probably worthwhile to differentiate between local network access and remote network access, and also differentiating between spinning disks and SSD. Local gigabit network ping time is 200 μs and an SSD typically reads a 4K block in 25

It's not a reliability number. For comparison, right now 31% of California's energy comes from renewable sources (according to wikipedia). What 99.9% means is that they'll keep some traditional power generation mechanisms, like gas turbine

Unless I misunderstand things, a valuation of $150m means that the company is worth $150m, not that they'll be raising that much. Instead they'll be selling a shares of the company at that valuation, so if they sell 10% they'll get $15m.

This seems like a business opportunity. You could create a third-party linode storage service, and proxy through nodes inside their network so that your clients don't have to pay for the bandwidth. You could just store the files on S3 but

It's especially good since storage can be overallocated. The odds that upon hearing the announcement everyone fills up the new space is slim, so adding 20% more storage doesn't add 20% more costs.

You can get a feel for this by running netstat -tn and then running a traceroute to each connection you currently have open. For example, my connection to news.ycombinator.com takes this path: Salt Lake City Denver Dallas Houston My connect

In 2006 I helped put in an OpenLDAP server in a medium-sized company (150 users). Once we'd gotten past the initial hump of configuring everything to work with it, it was really nice to have single sign-on and a list of users and permissio

Bounces should go to the "envelope from address", which is different than the from address in the actual email. The way I've set this up before had the envelope from address be "bounce-$user_id@companydomain.com" so that we could identify

There are practical uses for ASCII animals. When I built a command-line tool to let the developers sign out for a 15 minute break at my last job (because doing it via the AS/400 interface was a big hassle), I used a big, yellow elephant [1

As HN users I suspect we're seeing a far greater quantity of brand-new bootstrap sites than almost every other group on the internet. I wouldn't sweat using bootstrap for your app if you're targeting a different group.

What's the power usage of old PCs like that? I've been using a sheeva plug as my server at home because it only uses something like 5 watts. It seems like ARM servers are the best choice for home servers. They have adequate processing pow

This seems to work well. It'd be nice if you could filter out images that aren't travel related, e.g. for "china" I got http://farm5.staticflickr.com/4071/4429271873_cb6163e9e1_q.j... .
