Mastering Light
·
· Score: 4, Interesting
Infrared is not a single color. It is a range of colors. The warmer something is the closer it gets to a visible color. Incandesant Light bulbs get so warm they become visible. The also continue to emit hugh amounts of infrared - in fact, the emit more infrared than visible.
I interpreted the article to say that they shift light like a audio pitch shifter may change the key of a song to be more conducive to a singers natural range. Cooler objects would be, say, red and warmer objects would look oranger.
If this has the efficiency they claim, you could get more visible light out of a standard light bulb. This would save energy.
I remember seeing a room where two THICK cables, thick as your thumbs, came together at a brick sized boxed that proudly proclaimed itself as a bridge. The left was simply labled "South Campus." The right was "North Campus."
The connector (I forget the name, but think of BNC on steroids) was applied to the cable in two parts the first part pierced the solid sheath so the second part so make contact with the inner core.
Ahhh
You know, Nastalgia just isn't what it used to be.
Obviously this is still a long way from running my laptop. But, does anyone who might be involved in this stuff know what the projections are for how long a typical "charge" will last before you have to "recharge." The metaphor being how long you can go before you must resupply nutrients and/or enzymes and/or biologicals.
I agree.
As someone who remembers when platform shoes, leisure suits, and polyester pantsuits were in-style, declarations of "End of Fashion as we know it," were not always bad. To this day, I cringe at anything plaid.
It will be regretable that some good stuff about the Internet will be the victim of "improvements." Let's hope that some things make a comeback.

There is one obvious hole that I found.
They turned off the last file access on the Windows servers, but not the Linux servers. Every file hit on Linux got turned into an I-Node update that didn't occur to Windows.
This can be done by "mount -o noatime/mntpoint"
Airlines make nearly zero money on those things. In fact, if you factor in the effort to keep them working, it's probably a loss.
There is a case of a cell phone in a baggage compartment that gave a false positive of the aircraft smoke detector.
Where I work, the real issue isn't Linux/(Open,Free,Net}BSD versus MS Windows {XP,NT,2K} - The competition is HP-UX/AIX/Solaris.
Anybody like to cite interesting portions of the EULA of those systems?
I agree with that right up to the point where the difficulty in use prevents an administrator from doing the right thing.
Security should be easy to implement and difficult to circumvent.
Remember during the OJ Simpson Trial? Time and Newsweek both had the identical "bug shot" on their covers. One significantly changed the tone of the shot which made him look much more menacing. With both images on the news stand, it was clear that the change altered the editorial impression of the photo.
Most "premium" software is developed internally for non-IT companies to solve a need unique to their industry. Consider airline reservations systems and the airline industry.
It would be "tricky" to manage what a large multi-national does for offshore programming.
It seems to me that since this is a glorified transformer, the amount of energy lost in the transfer would be MUCH higher than a classic wall-wart.
People with transformer isolated data centers know that you typically loose 2% to 5% of the energy going into the unit as raw heat.
I can't imagine this thing would get better than 60% efficiency.
The US legal system is relies heavly upon precedent. If they win, it automatically makes it much easier to win against microsoft. Basically microsoft would be defending against two suits.
It's been over five years since I worked on an ISDN provisioning project, but this is what I think I remember.
The problem is fundamental to the design of 5ESS switches. 5ESS is a very commonly used Telephone Switch. Every piece of active Office Equipment (OE) needs a Telephone Number (TN).
The OE loosely corresponds to the rack, shelf, and channel that your wires go to. Actually, there are more layers of indirection that aren't relevent.
Even if you had three analog lines, but only needed one TN, the other two lines got a TN because the switch needed to know what the roll-over TN's were. You couldn't just rollover to another OE number.
Even if Bell Core fixed the 5ESS to be less TN dependent, many Bells have Billing systems, Loop and Circuit systems, and Provisioning systems that are designed with the TN as a primary key.
In addition to the technical design issues, you've got natural human change too. The people who do the exotic switch programming (routine programming has been automated) are of the type, "I've been doing it this way for thirty years."
It's just easier to make the TN bigger.
I think a good case could be made that if a site has a/robots.txt file and that file allowed an automated "SlashBot," then the slashdot could/should create a mirror.
Because both the defense and prosecution agreed that ElcomSoft sold software designed to crack copyright protections, the case essentially turned on ElcomSoft's state of mind during the period it was offering the software.
It was a "Don't punish us because we didn't mean to this bad thing."
I remember reading Ringworld by Larry Niven. I talks about a character being a "Wire Head," someone who is addicted on electronic pleasure. In their society, it is considered socially unacceptable to have such an implant. Some alien races have even developed a remote device that can do the same thing from afar - which have been baned by treaty.
It's a great book that every Good Geek must have in their library
I think to qualify as an analogy is has to be a reasonable comparison.
When the Desert was conquered, the "explorers" didn't have to worry about bringing a self-contained environment that, if breached, would kill the travlers in under a minute.
The "explorers" didn't have a hyperactive media that chronicaled every death, especially the women and children. (remember how Christa McAuliffe got all the press) There were lots of people who died getting from east to west. The Chinese slave^H^H^H^H^H laborers who built railroads.
The current space infrastructure is based upon the current aerospace ideology that all possible engineering go into making sure that "wagon" reaches the other side of the desert and back since the other side of the desert is just as deserted as the desert itself!
I for one, am glad that when a rocket launches, with zillions of pounds of fuel, it did so because lots of people said it is safe rather that it might be safe. Think what could happen if one of the solid rocket boosters tipped sideways while ignighted. There're no pumps and can not be shut off. It shuts itself off only once it has spent all of its fuel. It could easily wipeout Disneyworld on its way to Tampa.
I like NASA just the way they are.

Let me suggest that fluid dynamics and related fields of computational fluid dynamics and areodynamics are very nerdy.
The certification is just documenting that your security model. The fact that Microsoft can demonstrate the following features:
Audit
Cryptographic Support
Communications
User Data Protection
Identification and Authentication
Security Management
Privacy
Protection of the TOE Security Functions
Resource Utilisation
TOE Access
Trusted Path/Channels
Is all that's required for the certification. Does the OS have the right features with a configuration policy that sets those features properly.
It's sad that it's miles away from the default install, and most sysadmins won't take the effort to implement them.
Also, buffer overflows aren't part of the certification. Although, I would make a strong claim that a buffer overflow in a process running as System violates Protection of the TOE Security Functions
Showtime had the series for five seasons. They syndicated it - with a lag of about a year. A big complaint about SciFi picking it up is that they jumped into season six with a bunch of fans (including me) lost on the background of a cast change.
It doesn't really have a strong arc in that if you miss an episode you're lost for weeks. There's a few arch enemy races that are always lurking ready to pop up into some episode. There good aliens too who help out, sometimes.
They avoid "techno-bable" by just accepting that there are aliens out there who make cool stuff we humans just can't understand. "We don't know how that works," is a frequent line.
Another key success factor is the great cast. Anderson gets some great one-liners and brings a good dose of humour to the show. Tapping and Shanks are totally convincing as the shows eggheads. The supporting cast could easily lead in their own series.
I sure the show syndicated because there's money to be made.
The patent approval process is quite lengthy. A common critisism of The System (tm) is that it's easy to drag the process on for some time until someone else has built something that might be infringing. The approval processes suddenly speeds up so that the patenting company can torpedo the "infringing" product.
Under the UID 0 approach, all calls needed to do something. I haven't peeked at the code, but if I were to solve the problem, I would frontload the overhead of the syscall policy evaluation to the exec() call, store the results in a bitmap field. From there, it's bit math. A if (priv & PRIV_SOMECALL) has no more overhead than if (uid==0)
Well, given unlimited access to equipment (as in your vat of molten lead example) Here are some good demos that ive personaly seen:
I like putting about a 1/4 cup of sugar into a coffee mug, then add sufuric acid. The acid carbonizes the sugar and this black mass rises from the coffee mug. Don't expect the use the coffee mug again.
