No, we should make our acceptance of [the existence of] the problem not be conditioned on (proposed) solutions. You are free to propose other solutions, and the choice of _which_ solution often politics and opinion. It's a variation of "everyone is entitled to their own opinion, not their own facts."

+ - Help stamp out CVS and SVN in our lifetime->

mtaht (603670) writes "ESR is collecting specifications and donations towards getting a new high end machine to be used for massive CVS and SVN repository conversions, after encountering problems with converting the whole of netbsd over to git.

What he's doing now sort of reminds me of holding a bake sale to build a bomber, but he's well on his way towards Xeon class or higher for the work.

What else can be done to speed up adoption of git and preserve all the computer history kept in source code repositories?"

Comment: netperf-wrapper from bufferbloat.net (Score 1) 294

by mtaht (#48108835) Attached to: Ask Slashdot: An Accurate Broadband Speed Test?
Over at bufferbloat.net we have developed several pretty accurate bandwidth and latency measurement tests, that work at speeds up to 40GigE. We wrap the popular with the linux-netdev's "netperf" tool with something that can aggregate and plot the results, called "netperf-wrapper". The most popular test in the suite is called "rrul" which stands for "Realtime Response Under Load", but there are many others in the suite. It has been used to extensively tune several fair queuing and aqm algorithms, notably "fq_codel" which is in cerowrt, openwrt, and many other 3rd party firmwares. Its been used to debug network hardware, wifi, cablemodems, and most recently during the 40GigE batch-bql patchset now entering the linux kernel. Some examples of use to tune a smarter queue management system against modern day cable modems: http://burntchrome.blogspot.co... http://snapon.lab.bufferbloat.... There are also netperf-wrapper results for 40GigE, DSL, and wifi spread around the Internet. The intermediate format netperf-wrapper uses to store its results are in json and parsable by anything, and I keep hoping someone will get around to writing a web interface for the datafiles... Nothing else I've ever seen even comes close to netperf-wrapper for finding good, accurate, long term numbers and multiple forms of anomoly. Pretty much all the web based tests get increasingly inaccurate above 20Mbits. Single threaded TCP tests are bad also as they generally result in someone defeating TCP congestion avoidance in pursuit of the best benchmark numbers. [2] Far more important to the debloaters is not the bandwidth attained but the latency induced while getting it. [1] We maintain several public servers for netperf-wrapper, all connected via a gigE connection to the internet. Thus far we haven't overloaded them (nor advertised them widely), but if you want to give netperf-wrapper a try, and can't set up your own netperf server on the other side, feel free to ping us on the bloat mailing list for some addresses on various continents. [1] A brief rant: Bandwidth != speed. Bandwidth is capacity/interval. Real perceived speed is obtained via low latency. [2] I really hate that all the web network measurement tests don't simultaneously measure ping while running their upload and downloads. IF ONLY those tests would do that, people would start to realize that there is a huge tradeoff between good latency and high bandwidth, and that they are doing their networks in, by optimizing for bandwidth only. Networks engineered for speedtest's current test, *suck* for voip and gaming. I'd like to petition them to at least report ping times under load to the 98th percentile.

Comment: "Waste" (Score 3, Insightful) 71

While I find the 3d printing damn cool, the editorializing about the waste struck me as an odd comment for subby to make. I'm guessing that a lot of powder gets left over by this new process just as milling from a solid block leaves shavings. But those should be just as easily melted down and recycled in the next job, so not really wasted. (And if they are thrown away, it means that reusing them just isn't economical, so the 'waste' isn't that valuable anyway.)

I think the better argument where 3D wins is the ability to get arbitrary shapes that could be impossible to make with traditional machining or casting.

UK Seeks To Hold Terrorism Trial In Secret 240

hazeii (5702) writes in with news about a secret trial set to take place in England. 'A major terrorism trial is set to be held entirely in secret for the first time in British legal history in an unprecedented departure from the principles of open justice, the court of appeal has heard. The identities of the two defendants charged with serious terror offences are being withheld from the public, and the media are banned from being present in court to report the forthcoming trial against the two men, known only as AB and CD.'

There's a great short story about an AT-AT test pilot doing war-games for the brass and the weapon's designers. In one test engagement against A-wings he has the new AT-AT kneel down before shooting back. When they ask him why afterwards, he explains that he thought the A-wings might try to trip him up. After horrid stares amongst the designers and their bosses, they decide the best "fix" is to ship his smart ass to Tatooine so they can sweep it under the rug and stay on schedule.

"Inner Light", a favorite. It still gets a little dusty in the room when it's on. The flute went for mondo-bucks at auction, and is one of the rare examples of actual continuity in the show. (Beverly remembering they had a freaking Sun Shield a few episodes later. And using it once! Being another rare example) I will say that the Wesley episode with Ashley Judd had....redeeming qualities. And disqualifies Wil Wheaton from complaining, ever, about being Wesley.
