UN Report Reveals Odds of Being Murdered Country By Country

arielCo Re:shenanigans (386 comments)

The Venezuelan government hasn't published violence statistics for years, so NGOs and journalists query the morgues every week. But that doesn't stop the nomenklatura from denouncing the state governed by the most prominent opposition candidate as having "the most murders" (it's not clear, and not too relevant, whether they mean count or rate).

China Using Drones To Spot Polluters

arielCo Re: Unless (35 comments)

Normally you'd wait for the inspector to come, then make your proposition. If you can't even see him, you'd have to find out who he is and pay him a visit, o bribe his boss, which costs more.

China Using Drones To Spot Polluters

arielCo Re: how "green" is the use of them? (35 comments)

Arguably less than the reduction in the factories it'd catch during its service life? Even if it were a pick-up truck the tradeoff is just silly.

But the thing here is that it's easier to check on a big industrial park or mining operation from the air, and a lot cheaper if the aircraft doesn't have to carry a pilot and an observer.

Intel's New Desktop SSD Is an Overclocked Server Drive

arielCo Re:The caps are electrolytic (111 comments)

The regulators are there - you can see the 'big' coils in TFA. The capacitance for a simple "drain till you drop" scheme would have to be a lot here - very roughly 2*Energy/efficiency/(Vddmax^2 - Vddmin^2). So, step the voltage up optionally, keep the caps charged as high as practical, squeeze them dry when needed through a step-down converter.

TFA also says that the drive periodically monitors the "status" of the caps; I'm not sure if that means charge level or charge-holding capacity but it could test-discharge one cap at a time.

Intel's New Desktop SSD Is an Overclocked Server Drive

arielCo Re: The caps are electrolytic (111 comments)

* This is effectively regenerative braking, which I'm not sure you can do with a stepper motor.
* The arm servo needs extra energy; not sure the platter+rotor have enough.
* What if it's stopped, heads unloaded, when the power fails?

Intel's New Desktop SSD Is an Overclocked Server Drive

arielCo Re:The caps are electrolytic (111 comments)

The caps only need to supply enough juice to sync the RAM buffers to flash to ensure consistency of its internal block-mapping metadata (the filesystem should handle the rest through journaling and whatnot). The caps are rated at 35v but let's assume that they're kept at 12v: E = (12 v)^2 * 47 uF / 2 = 3.4 mJoules. Even at full operating load that should last for half a millisecond counting losses, but when power goes out the drive is going to stop serving requests and all it has to do is write that 1 GB buffer to a few flash blocks. More than enough, methinks.

Intel's New Desktop SSD Is an Overclocked Server Drive

arielCo Re:The caps are electrolytic (111 comments)

tl;dr: these are storage caps, which don't endure the ripple currents that kill filter caps.

Electrolyte decomposition is usually caused by high ripple current, which is why caps pop mostly (only?) when used as filters, as in motherboard DC-DC converters and gadgets powered by wall-wart adapters. In this particular application, the PSU impedance is quite low and the caps are handled by on-board regulators (V=Q/C and all that), so there's no load ripple and the caps just have to sit pretty and charged with insignificant heat losses until the computer is shut down or outage occurs. Maybe that's why Intel didn't even bother to use the solid (polymer) kind.

If these caps dry out due to age or bad quality they just won't hold as much charge for emergency sync'ing, which is still better than ordinary SSDs/HDDs with no caps.

Open Source Video Editor Pitivi Seeks Crowdfunding to Reach 1.0

arielCo Re:You already have Blender 3D... (79 comments)

Good to know this. Still, isn't it a bit like starting your car to play some music on the stereo?

Just imagine one's proverbial parent firing up Blender just to edit some Little League videos.

One would hope it could be run as a standalone program.

Eating. Beer. Coffee. Hardware for building & testing.

Perhaps hiring freelancers to help or not having to work freelance themselves.

But most likely beer.

Fishing Line As Artificial "Muscle"

arielCo Re:Fly fishermen have used this property for years (111 comments)

Do you mean that the treated nylon re-twisted spontaneously upon heating? I already know that to make a tight knot on a stiff material you can soften it with heat, but this is about "shape memory" - twist, heat, relax; then it will coil up actively when heated:

Spinks says they attached the fishing line to an electric drill and applied tension to the thread.

As it twists, the fibre forms tight coils in a spring-like arrangement. Once heat is applied to the coils it permanently fixes that spring-like shape.

Spinks says to use these springs as artificial muscles heat is again applied, causing the whole coil to contract.

Venezuelan Regime Censoring Twitter

arielCo Re:No evidence for censorship (152 comments)

Venezuela is just about the safest place for dissidents in Latin America, not the worst. For a start, consider "reporters without borders", they're a US-funded "freedom" lobby group. Very anti-communist.

Read their headlines about Colombia:
https://en.rsf.org/colombia.ht...

Now read their headlines for Venezuela:
https://en.rsf.org/venezuela.h...

The Colombian journalists problems are all murder, threats, intimidation by pro-government fascist death-squads.

The Venezuelan journalists problems are more along the lines of politics and bureaucratic red tape. And those are the WORST abuses that Reporters without Borders can highlight about Venezuela.

I don't know much about the threats on Colombia's journalism but I can tell you a few things about Venezuela. Trust me or call me a liar at your discretion:

* There are laws regarding "truthful and opportune information" and making "disquieting" and "destabilizing" speech a felony. Of course, no definitions for these fuzzy adjectives.
* Detention and/or beatings by military and govt-friendly gangs; it is not unusual for both to confiscate the memory cards and tapes. There's some mention of this in the RSF link you posted.
* One columnist was fined heavily for writing one of his pieces as a letter to Chavez's young daughter. Mind you, he didn't attack her in any way - he sympathized with the burden of being Chavez's daughter.
* The main opposition TV station, Globovisión, was accosted with fines (a recent amount was 10% of their gross revenue) for everything from donating airtime to broadcasting "disquieting" spots by NGOs. Eventually the station claimed being financially inviable and was sold to friendlier investors with a new editorial line, which has caused most reporters, interviewers and anchors to resign over the last year.
* In the months after the telecom regulator discretionarily revoked the broadcast license to another station, the gov't summoned the owners of two other stations with a milder but also critical stance. One became neutral-favorable, and the other came just short of a lap-dog.
* I hope you're aware about the tight controls on currency exchange. Well, every newspaper is facing a heavy shortage of currency for importing newsprint except state-sponsored and friendly ones. Maduro himself has yelled in public "not a single dollar more for the bourgeoisie!".

Now, ask yourself since Colombia is so much WORSE than Venezuela in protecting journalists, why do you never hear a peep in the media about how bad it is? Perhaps because there is no oil there?

*Ahem*

Oil - production: 588,000 bbl/d (93,500 m3/d) (2008 est.)
Oil - consumption: 267,000 bbl/d (42,400 m3/d) (2007 est.)
Oil - exports: 294,000 bbl/d (46,700 m3/d) (2008 est.)
Oil - imports: 12,480 bbl/d (1,984 m3/d) (2005)
Oil - proved reserves: 1,323,000,000 bbl (210,300,000 m3) (1 January 2008 est.)

Economy of Colombia

And oil shipments from Venezuela have been always on time, in spite of all the rhetoric.

arielCo Re:So much disinformation... (152 comments)

Maduro is just the fall guy to Chávez's irresponsible borrowing and waste of the country's reserves. Chávez died at about the right time to preserve the myth, so many chavistas blame Maduro for the train wreck since early 2013.

La Patilla is a popular opposition news site (slow but not actually blocked). Pastebin was used to distribute the links to some leaked emails last year. Anonymouse is quite popular with opposition Venezuelans trying to circumvent actual or perceived blockings.

Pussy Riot members jailed for two years for hooliganism

arielCo arielCo writes  |  about a year and a half ago

arielCo (995647) writes "Three members of Russian punk band Pussy Riot have been jailed for two years after staging an anti-Vladimir Putin protest in a Moscow cathedral. Judge Marina Syrova convicted the women of hooliganism motivated by religious hatred, saying they had "crudely undermined social order".

On 21 February, as a part of a protest movement against the re-election of Vladimir Putin, four women from the group came to the Cathedral of Christ the Saviour in Moscow, crossed themselves, bowed to the altar and began to perform a song asking the Virgin Mary to "drive Putin away" and describing the openly pro-Putin Russian Patriarch, Kirill I of Moscow, as someone who believes in Putin rather than in God, but after less than one minute guards cut short the performance and escorted them outside."

Venezuelan Govt seeks Internet content bill, NAP

arielCo arielCo writes  |  more than 3 years ago

Ah, none is more coward! (995647) writes "Several local and international news outlets report that the overwhelmingly pro-Chávez Venezuelan National Assembly is considering to reform their Social Responsibility law to include Internet content. Besides regulations on mature content and mandatory airing of government messages, the existing bill includes broad prohibitions against "destabilizing" and "disquieting" content.

The Assembly will also propose a proposal for a single national Internet access point, "with a view to handling outgoing and incoming traffic in Venezuela"."

Laser 'tattoos' for labelling fruit

arielCo arielCo writes  |  more than 4 years ago

arielCo (995647) writes "Those helpful-yet-annoying little stickers on fruits that tell the cashier the variety and brand may be replaced with a CO2 laser etching. Quoth the PhysOrg article: "the laser cauterizes the peel, much like when a laser is used on human skin. The cauterized area is impenetrable to pathogens and decay organisms and resists water loss". Demonstrated on a grapefruit, it is due for testing on "tomatoes, avocado and other citrus fruits". The original paper (abstract) requires a paid subscription."
