Serious Network Function Vulnerability Found In Glibc

redelm Raspbian vulnerable (210 comments)

According to directions side-thread, glibc versions prior to 2.19 are vulnerable. Checking my machines, Slackware-current and Lubuntu-14.10 are fine. Only my poor tiny Raspberry Pis are vulnerable (2.13). But they run slowly enough I can watch the gethostbyname() lookups myself :)

Verizon, Cable Lobby Oppose Spec-Bump For Broadband Definition

redelm Re:What about bandwidth OUT of the concentrator ?? (255 comments)

Apologies, I meant "guarantees" in a rhetorical not legalistic sense.

Shared media contention (10base2, unswitched 10baseT) collisions are somewhat different from saturated upload throttling download (ACK delays). As you point out, topography can help the former but the latter needs something smarter (QoS?)

I believe the current "cloud" service model puts _much_ heavier stress on upload as devices sync large photo and video files. So asymmetric services are out-of-balance.

Verizon, Cable Lobby Oppose Spec-Bump For Broadband Definition

redelm What about bandwidth OUT of the concentrator ??? (255 comments)

Fine to have good bandwidth from an ISP hub (DSLAM or DOCSIS server) but what guarantees it is available?

I have noticed that during the Internet rush hours (mostly evenings 4-10pm, especially Sunday) that many providers underprovision their upward links. (I'm not hitting loaded servers.) I have only a 6/1 and often I cannot get 3/0.5 .

This will be a very local thing and depends on how much the ISP has [over]sold and your neighbors usage (both cable and DSL). YMMV.

Ask Slashdot: Where Can You Get a Good 3-Button Mouse Today?

redelm Ergo often has 3. (429 comments)

Check out some of the ergonomic mice. Not inexpensive, but demanding minority products seldom are.

Personally, I like the Evoluent vertical mouse. Reduces pronation (twist) and available LH as well as right.

Your Entire PC In a Mouse

redelm Wrong form (165 comments)

You could do this easily with a Raspberry Pi ARM, especially the A+ (200mA) or something a bit larger like the Banana Pi (350mA) or for x86-64 devotees, an ECS Liva (550mA@5V).

I use these and form factor is the issue -- the tiny things become like octopus hubs with a number of cables in & out. Some like the HDMI are fairly heavy and stiff. The little board/box gets lifted and controlled by the cords.

I'd never want a mouse with those cables tying it down. The Chromecast-style HDMI stick (one coming from Intel) is a bit better, but what happens when your HDMI port is upside-down or inaccessible for all the other cables? Then you need to find a rare MF extention cable or FF coupler. HDMI does not provide enough 5V power (50 mA IIRC) to power a CPU.

LAPD Orders Body Cams That Will Start Recording When Police Use Tasers

redelm Official [non]Compliance (219 comments)

"You want it -- you got it! Only we'll be sure to make bodycams useless." [LAPD] Recording after discharge only captures the damage done for which there is also medical evidence. As mentioned side-thread, it does not record what lead up to the discharge and justifies it. Or not.

Some Police officers may dislike continuous monitoring. (I suspect many don't mind, probably the more honest.) Yet monitoring is routine, nearly universal in the private sector anywhere a dispute may arise. Often at police recomendation!

Do Police Officers think they are "Special"? If so, it is the "short bus" kind :)

$35 Quad-core Hacker SBC Offers Raspberry Pi-like Size and I/O

redelm Re:Meh -- already done on a Banana pi (140 comments)

And that is the key -- enough CPU to run a "modern" browser. Of course the specs are different -- so are the various unamed RPi model "B" (no fuse, 256MB, with holes, ...). The key with hardware is what it will run.

Can the US Actually Cultivate Local Competition in Broadband?

redelm Self-competition (135 comments)

The easiest way to increase competition in monopolistic settings is to encourage/enforce self-competition. Who is Microsoft's most difficult competition? Previous versions of its own software! Similarly, if net neutrality unhappily fails, then ISP have to offer both plans with audited kickback differences only affecting pricing.

Net neutrality is misunderstood by both sides. There is no "fast lane" -- everything travels as fast as possible. The only way ICS to implement a non-neutral net is to buffer/drop certain selected packets at times of congestion. That shunts them to the "slow lane", perpetrating a systematic fraud (viiolating promised "best efforts" for benefit) upon both ISP customers and upstream providers.

Duke: No Mercy For CS 201 Cheaters Who Don't Turn Selves In By Wednesday

redelm Just a different kind of Test (320 comments)

Mercy, from a bureaucracy? Please don't make me laugh so hard. As others have said, if they had evidence, they'd use it. Here, they are entrapping confessions with [false] inducement.

But really, all educational institutions have moved from education more towards filtering/certification (why else all the accreditation?) In this mode, success however gained _should_be_ rewarded. If some rat can weasel out marks, why won't s/he weasel out IRL?

How To End Online Harassment

redelm Ends justify means ? (834 comments)

Certainly ad-hominem (of which harassment is but an extreme form) is essentially a concession of the logical argument in favor of the opponent. It is nonetheless used (heavily in politics) because the target audience is untrained in recognizing fallacies.

In arguing against harassment, exception (or silence) is often made for topics one feels righteously passionate about (climate change, Holocaust deniers, etc). If one cannot defend one's enemies against unfair attack, then it is unprincipled and merely opportunistic to defend anyone else, especially one's allies.

Canadian Police Recommend Ending Anonymity On the Internet

redelm C O R R U P T I O N ! (231 comments)

This looks like the OPP wanting to make their jobs easier. Guess what? Policing is not supposed to be an easy job and certainly not by short-cutting individual rights. Such short-cutting is a form of corruption -- doing something for their own benefit (better collar record).

The cops need to get out of Timmy's and do some real police work tracking down perps. Not asking their jobs be made easier at everyone else's expense.

Ask Slashdot: Where Do You Stand on Daylight Saving Time?

redelm Changes in Latitudes, Changes in Attitudes JimmyB (613 comments)

Most modern lives revolve around clock-time, so DST/summer time makes some sense at middle latitudes -- more natural light when lamps otherwise would be burnt in the early evening (less in the morning when fewer are burnt).

DST make no sense at all at lower latitudes with little change in daylight hours with the seasons. Nor at very high latitudes with extreme changes.

A bigger question is whether the benefit is worth the circadian disruption -- world-wide jetlag. This is similar to countries deciding to be on half-hour time zones -- is the benefit worth the confusion? There will always be differing values, so differing opinions. No answer unless we can set 1h jetlag = XX kWh . You can try with money as the scale, then I suspect the answer is NO DST even at middle latitudes.

Ask Slashdot: Can You Say Something Nice About Systemd?

redelm Fight! Fight! Fight! (928 comments)

The nicest thing about systemd is that it is _NOT_ sysV and it is fighting/displacing sysV-style inits. Not that it is any better, mind you.

I like BSD-style inits (run Slackware) and I enjoy the controversy in a cautious "the enemy of my enemy is my friend" way.

Pope Francis Declares Evolution and Big Bang Theory Are Right

redelm Non-linear time (669 comments)

What conflict? I never saw any, except for strict literalists (blasphemers) who believe that G-d's "Days" necessarily are the same as ours with 1440 minutes. What if They average 3 billion of our years? Not necessarily linearly constant either. Space is not, why should time be?

Firefox OS Coming To Raspberry Pi

redelm Re:Low power CPU meet bloated pOS (88 comments)

The Atom tablets are below that, but do not have HDMI output. The SBCs have been there for a while (a bit more expensive), but suck more power 20W vs 1.2W. I have and use both, still like my RPis.

How To Beat Online Price Discrimination

redelm No Haggle ! (163 comments)

This looks like the electronic equivalent of haggling in a shop [bazaar]. Contrast this with the [anglo] best-price, take-it-or-leave it across multiple competitors. As a consumer, I vastly prefer the latter. As a seller I might prefer haggling (tied customers), but only if I have power when I buy (often I'm as tied).

A consumer negotiating with a seller is a grand delusion. The seller knows far more about their costs and market demand than you ever can. They spend their careers at it. All you can do is walk away, hopefully there are competitors. IMHO, this is the great different between First- and Third-World economies -- competition in the former, and very-restricted (cronyism) in the latter.

So I stay away from anything that looks like haggling (even MiR). That is my only choice.

Ask Slashdot: Handling Patented IP In a Job Interview?

redelm Solving Tough Problems ... (224 comments)

This sounds like a tough problem -- you've thought about it, examined many angles, yet cannot find a clear winner. So time to bring out the PHB decision tool, Flip a Coin!

Seriously. You've examined all the alternatives rather thoroughly with more data & values than we can know yet cannot determine a winner. They must be evenly balanced, so a coin toss (PRNG) is as good a decision method as any other. If you insist on persistantly over-thinking this question, then devote your efforts to finding something _new_ that turns the question into a slam-dunk.

ObOnTopic: If you mention the patent, many HR types will assume you assigned it to a previous employer. They might be impressed, or they might worry their software will be contaminated/infringe this other company's IP.

NSA To Scientists: We Won't Tell You What We've Told You; That's Classified

redelm Who is surprised ? (106 comments)

First, there are the knee-jerk responses of an "Intelligence" organisation never wanting to let anything truthful be known about it, and particularly detesting FIOA requests. Traitors. Then there is the bureaucratic response of never saying anything lest you be accused of inaccuracy.

But there also is a real security concern for the agency involved -- in answering "what did you release", they burn clandestine "leakers" as stooges. I do not think Snowden was a deliberate leak, but unless proven otherwise I assume about half the leaks are plants.

I'll buy (may swtich to Linux) if it has a micro HDMI output so I can dock the thing at a real monitor (1960*1200 min). I've been looking around to tablets as desktop replacements and found relatively few x86 with HDMI out.

Copyright on game sequence video captures?

redelm redelm writes  |  about 5 years ago

redelm (54142) writes "What is the copyright legal status of a short-ish video capture from a PC/console game? For a pre-generated sequence like a fatality, the game.house could assert it was all theirs. OTOH, for a series of creative moves by the player the game pgm merely provides an environment for the creation. Rather like writing a computer program and using a compiler to make it executable. Or do the game houses get to copyright clay? This would influence whether they're youtubeable."

FCC in favor of Net Neutrality

redelm redelm writes  |  more than 5 years ago

redelm writes "Both the Wall Street Journal (here) and Reuters (here)are reporting the FCC Chairman Julius Genachowski will make a speech on Monday in favor of Net Neutrality. There's a big difference between a speech and a law, but irrespective of campaign contributions, the US Congress should not find this too hard to pass with the current strong populist scrutiny."

TW trying cable Caps + overage fees

redelm redelm writes  |  more than 6 years ago

redelm (54142) writes "Yahoo! reports Time-Warner will try out traffic caps on cable internet service in Beaumont, TX. They will charge an overage fee of $1/GB. Base included transfers will be from 5-40 GB/month. Most interesting was the justification — 5% of users using up to 50% of bandwidth. And that others have secret caps."
