I'm looking at you, Macbook Pro!

Cmd + up/down arrows. Not the best solution, but it works, and after a while, you get used to it!

It doesn't always work, some applications have Cmd-(up/down arrow) mapped already. However Fn-(up/down arrow) is always Page Up/Down, and (IIRC) Shift-Fn-(up/down arrow) is Home/End.

How far away was the guy in the costume from the principal's office? I'm not familiar with that school district but most public schools I attended were set back quite a ways from the road and sidewalk. If the blaster was black plastic, would you be able to distinguish it from a real gun from 100 feet away?

Using Google Maps and Streetview, you can see that school is tiny, it's about 200ft of frontage along a commercial-zone 2-lane road (+parking shoulders and sidewalks) sandwiched between two very narrow residential streets. The play area between the school and sidewalk is maybe 15 feet wide. So, even if this guy was on the opposite side of the commercial street, I doubt the principle would have been any farther than 100ft away at close observation, and probably much closer than that.

The news story photo definitely looks like it was taken in that generally vicinity, but I can't pin the location down, exactly.

Submission + - SourceForge hijacks Win-Gimp, wraps installer in adware-> 1

slashdice writes: Ars Technica (and, well, everybody other than slashdot) is reporting on the reprehensible behavior by SourceForge, Slashdot sister sister site. "SourceForge, the code repository site owned by Slashdot Media, has apparently seized control of the account hosting GIMP for Windows on the service, according to e-mails and discussions amongst members of the GIMP community—locking out GIMP's lead Windows developer. And now anyone downloading the Windows version of the open source image editing tool from SourceForge gets the software wrapped in an installer replete with advertisements."

lister king of smeg writes: What happened?

SourceForge, once a trustworthy source code hosting site, started to place misleading ads (like fake download buttons) a few years ago. They are also bundling third-party adware/malware directly with their Windows installer.

Some project managers decided to leave SourceForge – partly because of this, partly just because there are better options today. SF staff hijacked some of these abandoned accounts, partly to bundle the crapware with their installers. It has become just another sleazy garbage site with downloads of fake antivirus programs and such.

How can I help?

If you agree that SourceForge is in fact distributing malicious software under the guise of open source projects, report them to google. Ideally this will help remove them from search results, prevent others from suffering their malware and provide them with incentive to change their behavior.

As this story has been submitted several times in the past several days, by various submitter and is going around various other tech forums( https://news.ycombinator.com/i... , https://soylentnews.org/articl... , https://www.reddit.com/r/progr... ,) this submitter wonders has our shared "glorious Dice Corporate overloads" been shooting this story down?

Submission + - SourceForge assumes ownership of GIMP For Win, wraps installer in adware->

An anonymous reader writes: It appears that SourceForge is assuming control of all projects that appear "abandoned." In a blog update on their site, they responded saying in part "There has recently been some report that the GIMP-Win project on SourceForge has been hijacked; this project was actually abandoned over 18 months ago, and SourceForge has stepped-in to keep this project current. "

SourceForge is now offering "to establish a program to enable users and developers to help us remove misleading and confusing ads."

Submission + - First Ultraviolet Quantum Dots Shine In An LED->

ckwu writes: Researchers in South Korea have made the first quantum dots that emit ultraviolet light and used them to make a flexible, light-emitting diode. Until now, no one had succeeded in making quantum dots that emit wavelengths shorter than about 400 nm, which marks the high end of the UV spectrum. To get quantum dots that emit UV, the researchers figured out how make them with light-emitting cores smaller than 3 nm in diameter. They did it by coating a light-emitting cadmium zinc selenide nanoparticle with a zinc sulfide shell, which caused the core to shrink to 2.5 nm. The quantum dots give off true UV light, at 377 nm. An LED made with the quantum dots could illuminate the anticounterfeiting marks on a paper bill. If their lifetimes can be improved, these potentially low-cost UV LEDs could find uses in counterfeit currency detection, water sterilization, and industrial applications.

Submission + - Alloy Deforms, Springs Back Into Shape Millions Of Times->

MTorrice writes: By adding a touch of cobalt to an alloy of titanium, nickel, and copper, an international team of researchers has come up with a shape-memory alloy film that can be deformed at least 10 million times and still snap back to its original shape. The finding represents a remarkable improvement on previous shape-memory alloys, which, at best, could withstand only a thousand deformations before succumbing to structural failure.

The current, top-of-class alloy is nickel titanium, which is used in stents to open blood vessels and as orthodontic wires.

I do this for a living as an facilities electrical engineer who works closely with electricians. The phase between lines on the primary side of a single-phase stepdown transformer is irrelevant to the secondary side. Indeed, sometimes the distribution lines are Y configuration rather than delta, so the inputs to the single-phase transformer is sometimes line-neutral instead of line-line. In most systems worldwide the single-phase transformer has two poles on the secondary side, one of which is grounded locally and is connected to the neutral conductor, the other pole is connected to the "hot" conductor or "line voltage". There is typically about 240V between hot on neutral. A main electrical panel for residential will have 2 bus bars in this case.

In the U.S., the transformer is typically has a three-pole secondary with a center-tap connected to the center of the secondary coil. The center tap is connected to local ground as well as the neutral conductor, and the other two poles at opposite ends are each hot conductors. Since there is only one coil on the transformer secondary this results in two hots that while measured against neutral are 120V, but each 180 degrees out of phase with the other for a result of 240V between lines. A main electrical panel will have 3 bus bars in this case. You can confirm this with a voltmeter. (If they were 120-degrees out of phase, you would measure a SQRT(3) ratio of V_lineline/V_lineneutral.

Occasionally in a commercial or industrial facility, you may find a 2-pole electrical panel that is a sub-circuit to a three-phase Y-configured panel (120/208V Typical configuration). These tend to be remodel conversions from when the building mains were swapped from single-phase to three-phase. In this one case, you will get the 120-degree difference between lines. When this is the case you have to be extra careful when connecting loads to the subpanel, because the difference in line-line voltage is less than what you would expect at first glance, and some equipment may fail to operate, or operate in a degraded state, because of that.

The USA is running on 220-250V AC for residential (exact voltage varies per locale). It's single-phase with a center-tap neutral, sometimes called "split phase"; Typically, a neighborhood will be on one phase of three-phase distribution system. Split phase allows one get two half-phases of about 120V (typical U.S. receptacle, a.k.a. "power outlet"), but you still have 240V available for large appliances: electric stoves/ranges, furnaces, installed heaters (baseboard or in-wall), clothes dryers, and/or sometimes a welding receptacle in the garage.

Split phase is occasionally incorrectly referred to as "two phase", which actually only exists with one old electrical distribution system near Niagra.

They don't. The temperature record is Qatar and Kuwait is about 53C. http://en.wikipedia.org/wiki/L...

Official measurements don't get taken at or near surfaces of concrete, asphalt, tarmac, or compacted sand (that's why I mentioned the caveat about placement and calibration of the thermometers). My buddies and I were stuck working (albeit very slowly, for very short periods) in those conditions. I was just glad I didn't have to wear combat gear at the time.

During major U.S. heat waves we typically get a similar number of deaths, and that's with about 1/3 the population. There are quite a few places in the world that get worse heat without heat waves. The worst two I've visited were Kuwait and Qatar, both read 140F/60C on thermometers in the shade (placement/calibration technically didn't meet weather station standards, so no "world record", but that is still the temperature people were subjected to). Qatar was worse though, the humidity was borderline condensing (some surfaces were damp with not a cloud in the sky); I'm glad I didn't have to stay there any longer than one day!
