Which will last exactly as long as it isn't profitable to make a virus for it.

If everyone swapped to a certain distro of Linux, I'd be willing to bet you'd have major problems within a week.

Then why isn't there "major problems" with CentOS / RHEL which are on the majority of computers connected to the internet? Because they are running an Apache webserver instead of a Gnome desktop?

The truth is, Linux computers are heavily represented on the internet yet we still don't see anything significant in the way of Linux malware.

Someone should first wire up management to zap them every time they get an idea for a "brilliant" addition.

I had this at work today. Somebody arbitrarily decided to store 3 months worth of hourly MySQL backups. Never mind that they were being stored on the MySQL server itself (some backup!) but each backup was over 1 GiB - that is 30 GiB per day. 30 * 90 = 2700 GiB on a server with a 2 TiB hard drive that was already half full.

I enjoyed cleaning up that mess, but I as usual people with no technical knowledge continue to make technical decisions.

Do you only use languages that let you choose the language keywords? Surely there is leeway in how much bending to your will that you demand of a language.

If you indent your C, PHP, Java, or whatever else sanely, then you will have no issues with Python indentation rules. They are just the sane C rules, but enforced.

Jail isn't going to do any good unless you put the whole agency in jail.

When in the Course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature and of Nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.--That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, --That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.

Thanks, Jesse. I posted a review of the Leather Ducky on GH, but the images are gone due to their famous crash some time back:

I'll fix those images sometime.

If you ever do want to sell or otherwise be rid of some of the hardware in those pictures, please do get in contact with me! My Gmail username is the same as my Slashdot username. Thanks!

The tiles on the shuttle's belly were the complete opposite. The main tiles on the belly of the shuttle were roughly 10% silica fibers, 90% air. Think very low density styrofoam, except that it can be heated to glowing temperatures without losing its properties. This was actually the really cool demo that I saw. The person giving the demo heated it with a torch until it was glowing yellow/white, then picked it up with his bare finger tips. Because the thermal conductivity of it was so low, it could be handled (with care) with bare hands.

You might have notice that the person held the TPS tile by the corners, not the edges. Had he touched the middle of the tile, where he had hit it with the torch, he would have been severely burned. The amazing property of the tile is that it would maintain a high thermal gradient, so one part of it would be super hot but just 1 cm away it would be cool enough to handle. This is related to thermal conductivity as you mention, but it is not the heat transfer property that you imply (like 80 degree water scalding blesh but 80 degree air not scalding).

Better not catch you playing games on this thing or you're liable to start fires.

I'm more worried about cleaning it. This thing looks like a magnet for dirt, dust, and other airborne particles. When those particles settle on the heatsink it will ruin the copper-air interface and this thing won't cool at all.

I also wonder what happens when the inevitable patina develps:

Double slit experiment has been duplicated using *individual photons*. Yes, one photon fired at detector at a time. ONE. No more, just ONE. After waiting sufficiently long, interference pattern was produced on the detector. The photon appears to have interfered with itself.

I too, er, interfere, with myself when I'm alone after waiting sufficiently long.

You've linked to a non-English page, which is irrelevant to the English language.

Enceladus is not an English word. It is a Greek word, therefore I've linked to the Greek page. Though who know the Greek alphabet (physicists, mathematicians, engineers, i.e. a considerable portion of /. readership) will be able to read the word and understand how it is to be pronounced. Greek, unlike English, is pronounced how it is spelled.
