So 20 million Yahoo user names are revealed. Why is that interesting at all? I guess if I write a script which loops some id for a yahoo info page I get a similar list. Maybe a Google search is enough. Or do not contact external service, just guess: take all Japanese names, append one or two digits to it. Mostly these are valid names.

This pushed the attack upstream to their direct peers, largely Tier 1 networks. Tier 1 networks don't buy bandwidth from anyone, so the majority of the weight of the attack ended up being carried by them. While we don't have direct visibility into the traffic loads they saw, we have been told by one major Tier 1 provider that they saw more than 300Gbps of attack traffic related to this attack. That would make this attack one of the largest ever reported.""

25 W idle is quite impressive, could you describe what parts and other measures have you used to achieve it? Now I have 3 computers online 24h in my home alone, mostly idle. Two are about 60W at idle. The third is a Raspberry Pi, which only consumes a few watts, but it has an attached LCD display too.

Regarding servers: I believe the new servers has much better energy management, so the idle - full difference may be larger than once it was. I also found that it is very hard to achieve a - seemingly - full load, the type of test program makes a big difference in power consumption, even if top displays 100% on all cores in every cases.

+ - Google wants variable-rate Ethernet->

Submitted by
optikos
optikos writes "When it comes to the fill-rate fraction/ratio of digital-domain Ethernet frames in the underlying analog-domain physical medium, a senior network architect at Google wants to have more flexibility regarding the denominator to push a link's typical fill-rate closer to 100%. The current scheme of inter-Ethernet-frame idle capacity as represented by a numerator that is notably smaller than the (currently-standardized fixed-size) denominator in the fill-rate is claimed to be unsuitable when interconnecting data-centers.

The Institute of Electrical and Electronics Engineers Inc. (IEEE) isn't working on a variable-speed Ethernet standard yet, but Google is pushing for one. It was a point of focus for Bikash Koley, Google's principal architect and manager of network architecture, during a panel session on the last day of OFC/NFOEC last week. What he wants is variable-speed Ethernet. So, instead of running a connection at 100 Gbit/s or 400 Gbit/s, which are the two standard choices, he'd like to pick arbitrary speeds. The technology on the optical side is actually ready for what he's asking. Variable-speed transceivers and flexible-grid ROADMs exist. What's missing is on the packet side: a media access control (MAC) layer that's capable of dealing with a variable-bit-rate physical (PHY) layer.

I agree, the wattage must be measured. As another example, I measured 80W idle and 160 W on full load on a 12 core Opteron server.

This server does not have a 3D video card. I guess you also achieved full load on a 3D card too, and that explains the large difference between the wattage in idle and full load in your case.

+ - USPS discriminates against "Athiest" merchandise-> 3

Submitted by fish waffle
fish waffle writes "Suspecting that their strongly branded "Athiest" products may be treated differently by more religiously-oriented postal regions, Kickstarter success Athiest Shoes conducted an experiment. They sent 178 envelopes to 89 people in different parts of the US, each person receiving one envelope prominently branded as "Athiest" merchandise, and one not. The results: packages with the athiest label were nearly 10 times more likely to never be received, and took on average 3 days longer to show up when they did. Control experiments were also done in Europe and Germany---it's definitely a USPS problem."

Do most developers use caps lock for typing capitlized constants and other things?

Yes. Since I have learned touch typing, I use CAPS LOCK extensively. Like in the previous sentence. If I have to type more than two (or one?) upper case characters I always use it.

It was indeed one of the most difficult key to learn, maybe because if I accidentally hit another key, the usual Backspace does not correct it. But it is well worth to learn it. Otherwise I had to switch between LEFT SHIFT and RIGHT SHIFT after almost every character, which drives me crazy. I am not sure, but I assume, that those who hate CAPS LOCK never really learned touch typing well, if at all.

It is by no accident that there was a SHIFT LOCK key on every typewriter (and that was less useful than CAPS lock), which was mostly used by professional typists.

You can use a Kinesis Advantage keyboard. First, important keys are pressed with the thumb, not the right fingers (Enter, Ctrl, Backspace). Second, the keyboard is programmable, so you can map all problematic keys to the left side and type them together with AltGr (right ALT). I am already using this method, because our national characters take the place of almost every symbol characters, which are important for coding. It is working well.

I understand, too high temperature is one thing, but crashing is really bad.

The new models, which have onboard IPMI controller, send you an email if a sensor value is unusual. At least I always get a notification email when I open the case, telling me just that: somebody opened the case. I had no problem with temperature even when I run a burn-in utility.

This project is not about high-performance computing, much more about lovingly dusting off and maintaining a piece of hardware considered quirky by 2013 standards. And . Now the question creeps to mind: what software would Slashdotters run on such a beast, once it is upgrade to 12 procs and, say, 24 Gb of RAM ?"
