Comment Re:Dunno (Score 2) 234

They are latency-bound so HT just causes two requests to be outstanding simultaneously, effectively hiding the latency of one request behind another request. UltraSparc T2 was an architecture based around exactly this principle with eight threads per core.

In my experience, if software is well-written (e.g., you make sure you're bandwidth or compute bound), hyperthreads will definitely slow things down. How badly will depend on the exact workload. In all cases enabling hyperthreads will cause your system to behave a lot more variably, which is another thing one may care about.

For the above reasons HT off has been my default setting since it came out-- though ideally it's controlled from software: if you know you're gonna be latency-bound, then use hyperthreads-- otherwise only pin one thread to any single core. But that's without considering Spectre et al...

Comment Next time, sue the state (Score 3, Interesting) 307

Security professionals and tech enthusiasts should take note of this technique and apply it in reverse: instead of reporting vulnerabilities to the government institutes who caused them, bring those guys to court. Sue them for unsafely handling the information you entrust them with. Things are not going to get better unless this kind of incompetence can cost someone's head.

We all know there are always missing options in a poll, but here a whole class of answers is missing: filtered blocking.
I don't allow Google Ads etc. because they track. I don't allow sound ads, drop-over ads, nor pop-up ads etc. because what the fuck. Here's a solution for the mediacorps: go back to loading jpg ads and place them in sidebars, and everybody'll be happy. Don't try to be greedy and shove ads through our throats, because we'll just block them.

And to the online ads/marketing industry: you oversaturated your own market to the point people actively avoid your products, great job!

Comment Because that's all publishers do... isn't it? (Score 2) 125

Elsevier, the science publisher notorious for maintaining high-priced research journals in a time when web technology can accomplish the same tasks for a fraction of the price,

Because providing access is all a publisher does, right?

No. Top science publishing requires accessibility, good layouts, solid content, and excellent writing. Scientist make mistakes in content so we have peer review. Even more commonly, scientists aren't always excellent writers and this is why you have line editors. Publishers of old have enabled accessibility, peer review, and quality writing. The fact that publishing now has become cheaper, does not mean the latter two are suddenly free as this slashdot article implies.
It's okay that publishing science costs money. Really. As a publishing scientist I do dislike Elsevier, however, but precisely because they're skimping out of good quality line editing and typesetting.

Comment This is news, how exactly? (Score 5, Insightful) 187

Since years the hacker communities have raced to hack DRMs, and since even before DRM had that name it was that kind of `protection' that harmed the gaming experience of people who do pay for their software. EA should grow up and realise DRM is not harming sales; they are harming their customers. Of course we know EA doesn't care given that they like to harm their game devs as well as their own games as well. Join the boycott of these fools.

Comment Re:How to refund if the money's gone? (Score 1) 203

Precisely. The eBay thing is a bit exagerrated though; there is buyer's protection that works (I've had to used it myself). It is a rather abitrary process, though: I could take the iPhone, but in a brick, and then start complaining they sent me a brick. It's based on perceived trustworthiness, as should be backing a kickstarter.

Comment How to refund if the money's gone? (Score 1) 203

From TFA (since the slashdot `summary' does not specify any of the new rules): ``[upon failing,] creators are expected to explain what is happening and how the money was used, giving refunds to any backers who request them.''. Now, if, for example, MyIDkey `burned through' 3.5M$ of backed money, then how would those who backed it get a refund? The money's gone, period. The kind of risk is inherent to these kind of fundraisers.

Comment What? (Score 1) 314

``Through a Google Summer of Code project this year was work to emulate systemd on OpenBSD.''
What?

``so a student developer has taken to implementing the APIs of important systemd components so that they translate into native systemd calls.''
What?

``systemd-hostnamed, systemd-localed, systemd-timedated, and systemd-logind utilities''
The `d' at the end of each of those stands for `utilities'?

Seriously, please do some editing before posing.

Comment Seven solutions, all bad. (Score 1) 383

TFA actually speaks on seven ways passwords may be avoided, with biometrics being but one of them. All seven build on extracting unique identifiers from physique or behaviour. All seven are wrong because of one simple reason: if someone mimics whatever chosen identifier good enough (either by hacks or by actually mimicing me), how can I change my `password'? I can't. Trashcan.

Comment Meanwhile... (Score 1) 454

an Israeli from Tel Aviv estimates the success rate at 90%, which is thus high that some civilians actually go out and see the interceptions, instead of going into the shelters. Of course, Tel Aviv is farther away from Gaza and possibly has less rockets fired at them, but the difference in ground reports and what is reported here is staggering. Maybe these scientists need to dial back and first get some more data, instead of just looking at a couple of videos and/or photos.
