Comment Re:ext3 (Score 2) 210

+1 to this.

Unless you have a business case where you know you need something different, stick to what's simple and what works.

ext4 is also a nice option over ext3. It uses extent instead of bitmap block allocaiton which improves metadata efficiency with no downside.

Comment Re:SSL hardware acceleration? (Score 1) 92

With modern machines you only spend about 2% of your CPU handling the HTTPS part of the transaction, especially with HTTPS connection re-use handling. Back when they first started enabling HTTPS I calculated that it might take one more rack of machines to handle all the HTTPS needs for facebook in a worst-case situation. One rack is a drop in the bucket for the http front ends these days for service as big as facebook.

These actually exist in many cities now. I have a nice modern mid-sized apartment in San Francisco. It's loft style with concrete between me and my neighbors.

We had a few issues with some early-20's adults acting like they were 16 and throwing absurdly loud parties at 1am. Thankfully things have settled down and my building is fairly pleasant now.

In SF it seems like people in owner-occupied condos are much more civilized.

Yea, afaik all of the modern VW/Audi turbos are http://en.wikipedia.org/wiki/Variable-geometry_turbocharger. This lets them engage at lower RPM eliminating the turbo lag.

Most of the time I find people complain about turbo lag I find that they are shifting too soon which keeps the turbo spooled down. Small 4-cyl engines like to be above 2000+rpm compared to 1500rpm that you find in V8/V6 engines.

I was just thinking about this the other day. What we could really use is a 4 cylinder full-size pickup hybrid. For example the VW/Audi 2.0L turbo can do 208hp/258 lb-ft. An F-250 super duty 6.2L V8 is 385hp and 405 lb-ft. You don't even need a tesla-size electric motor (362 hp / 325 ft-lb) to make up the difference for accelerating. You could use a medium size battery pack of like 20kWh and get most suburbanites to work and back and still have enough towing capacity for their fishing boat.

Yup. An american (we grew up here) friend of mine just quit his US job and move to Germany. Apparently they're working out permanent residency after a very sort time in order to get tech people to move there. This doesn't surprise me with the number of really skilled German software people I know at my company. They want to stop the flow of good engineers to the US.

Probably a lot hotter than that. Drives are happy to run in the 40c range. CPUs in the 60-70c range. I'd expect the exit temp and hot side to be atleast 40c. The bigger the thermal diff between hot and cold the better. If you have a normal exit temp of 40c and a max of 50c, you can let your inlet temp range between 20c-30c. This way even when it's hot out you can get by with evaporative cooling.

Yea, it's not even hard. My girlfriend who is moderately technical was wanting to check some .xlsx spreasheets into her git repo but was annoyed that it wasn't plain text XML like she thought it was supposed to be. She's used to writing in docbook XML.

I helped here out by writing a quick script that would unzip the spreadsheet file and then xmllint (A tool she does know how to use, and suggested it) the files in the sheet so that they're easier to diff. Then she is able to just run the script before checking in spreadsheet changes and have nice easy-to-see diffs.

No, seriously, JQP has the right answer. If my manager couldn't understand a simple explanation about what version control is, why it's a good idea, and basically a function of business continuity and software/systems best practices I would do everything in my power to get them ejected as incompetent.
