NASA Announces Mars 2020 Rover Payload

dotancohen Re:How about wheels that work? (66 comments)

I think that you underestimate the techinical challenges to do what you are suggesting! There is not quite as much ice as you might expect, nor is there heat to melt it, nor are there nutrients for the bacteria. Ecosystems take eons to develop.

CIA Director Brennan Admits He Was Lying: CIA Really Did Spy On Congress

dotancohen Re:When will we... (247 comments)

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!

Quiet Cooling With a Copper Foam Heatsink

dotancohen Re:Pretty sure it wasn't the heat tiles. (164 comments)

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).

Quiet Cooling With a Copper Foam Heatsink

dotancohen Re:Normal use indeed (164 comments)

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:

More Quantum Strangeness: Particles Separated From Their Properties

dotancohen Re:Limits of Measurement (138 comments)

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.

Enceladus's 101 Geysers Blast From Hidden Ocean

dotancohen Re:2010: Odyssey Two (4th Edition) (39 comments)

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.

Lots Of People Really Want Slideout-Keyboard Phones: Where Are They?

dotancohen Re:Just get a case (543 comments)

Please don't give Bennett any ideas. I would be very happy indeed if someone were to remove from his possession _all_ his keyboards.

In fact, arguably tablets and phones are media _consumption_ devices, not media creation. Leave the media creation to the big names in IP, lest you infringe their property. Go back to consuming (spending), preferably multiple times for each device that you own. Can't have you watching on your phone media that is licensed only for your PC, that would be stealing from somebody's intellectual property.

Microsoft's CEO Says He Wants to Unify Windows

dotancohen Re:Death bell tolling for thee.... (322 comments)

Well, I found Server Core, but it looks like it has all the disadvantages of a GUI, and doesn't even support all Windows Server features:
http://msdn.microsoft.com/en-u...

It still requires RDP, still requires running a graphical server (though not full desktop), and won't run Powershell since it won't run .NET.

Well, we tried!

A Warm-Feeling Wooden Keyboard (Video)

dotancohen Re:S'not Wooden (82 comments)

Hi Jesse. I don't see mention of which switches are in the buttonplank. I'm rather partial to the Cherry Blues, will there be an option for them? I see mention of "switches quiet enough to use in a meeting" but an option for "switches which give terrific feedback" would be most welcome!

If you have no need for the uTron (can't type a mu in ASCII) in the pile then I would love to adopt it! Considering the price I think that the folks at Geekhack [1] would be most interested in comparing your keyboard to the uTron, the Kinesis, and the Truly Ergonomic. Let me know if you are interested in having me write a review. I can point you to my other Geekhack reviews if you would like.

By the way, I also mod my boards (reduced spring pressure, and even leather keycaps) so I know to appreciate a product made _just the way you like it_.

[1] Keyboard enthusiast website, I'm sure that you've familiar with it.

Microsoft's CEO Says He Wants to Unify Windows

dotancohen Re:Death bell tolling for thee.... (322 comments)

Windows Server has been doing this for a while, with some versions coming with full UI and others with just the CLI.

CLI for Windows Server? As in something vaguely resembling SSH? How do I get it?

I administer a bunch of Linux servers, not because I hate Windows but rather because "sudo aptitude update" is so much easier than click-mouse-drag-doubleclick-right-click especially with network lag. If there exists a true SSH replacement for Windows I would love to try it.

Ask Slashdot: How to handle unfixed Linux accessibility bugs?

dotancohen dotancohen writes  |  about 4 months ago

dotancohen (1015143) writes "It is commonly said that open source software is preferable because if you need something changed, you can change it yourself. Well, I am not an Xorg developer and I cannot maintain a separate Xorg fork. Xorg version 1.13.1 introduced a bug which breaks the "Sticky Keys" accessibility option. Thus, handicapped users who rely on the feature cannot use Xorg-based systems with the affected versions and are stuck on older software versions. Though all pre-bug Linux distros are soon scheduled for retirement, there seems to be no fix in sight. Should disabled users stick with outdated, vulnerable, and unsupported Linux distros or should we move to OS-X / Windows? The prospect of changing my OS, applications, and practices due to such an ostensibly small issue is frightening.

Note that we are not discussing "I don't like change" but rather "this unintentional change is incompatible with my physical disability". Thus this is not a case of every change breaks someone's workflow."

German dam bursts

dotancohen (1015143) writes "Thousands of people have been evacuated to safety in eastern Germany after a dam burst on the swollen River Elbe and farmland was flooded in an attempt to spare towns, with meteorologists forecasting more rain.

In Magdeburg, one of the oldest cities in eastern Germany and a regional capital, some 23,000 people were asked to leave on Monday as water levels in the Elbe rose to a record 7.48 metres — about 5 metres above normal and surpassing the level reached during devastating floods in 2002."

Linux-friendly major motherboard manufacturers?

dotancohen dotancohen writes  |  about a year and a half ago

dotancohen writes "I am tasked with building a few Linux machines for a small office. However, all the currently available motherboards seem to be Linux-hostile. For instance, in addition to the whole UEFI issue, my last install was a three-day affair due to the motherboard reporting a Linux-supported ethernet device (the common RTL8168) whilst it was actually using a GbE Ethernet device that does not work with the legacy drivers and didn't even work with a test Windows 7 install until the driver disk was installed. There are no current HCL for Debian or Ubuntu and I've written to Asus and Gigabyte but from both have received the expected reply: No official Linux support, install Windows for best experience.

Note that I did even turn to the two large local computer vendors asking if they could provide Linux-compatible machines ready to go, but neither of them would be of any help. What globally-available motherboards or motherboard manufacturers can one recommend today?"

Kubuntu 12.04 To Drop Support For Firefox

Study links sexual content on TV to teen pregnancy

Greenpeace penetrates French nuclear plant

dotancohen writes "Greenpeace activists secretly entered a French nuclear site before dawn and draped a banner reading "Hey" and "Easy" on its reactor containment building, to expose the vulnerability of atomic sites in the country. Greenpeace said the break-in aimed to show that an ongoing review of safety measures, ordered by French authorities after a tsunami ravaged Japan's Fukushima Dai-ichi nuclear plant earlier this year, was focused too narrowly on possible natural disasters, and not human factors."

Gigabyte's solution to the ASPM bug: use Windows.

I wonder if Gigabyte will provide the unlock keys for the EFI boot loaders with a policy as clear as this?"

AskSlashdot: Calculators with 1-2-3 numpads?

dotancohen dotancohen writes  |  more than 2 years ago

dotancohen writes "Although the telephone has the 1-2-3 key on the top row, most calculators and keyboards have 7-8-9 on the top row. Switching between the two destroys muscle- and spatial- memory. Do any slashdotters use a scientific calculator with 1-2-3 on the top row? I've already scraped and resoldered my Casio fx-82 calculator to have 1-2-3 on the top, and remapped the numpad in Kubuntu, but if there exist any calculators like this already on the market I'd buy two."

Paypal alternatives?

This month I tried donating to Anki (but Paypal is no longer serving Japan for donations) and Virtual Identity (which stopped accepting Paypal due to the Wikileaks incident). The authors of both software are looking for alternatives. What can we recommend to them? What reliable and inexpensive money-transfer services exist today? What do you use?"
