That's not the case here, and it's irrelevant. When I noticed the discrepancy between my camera's reported speed and my speedometer, I then compared it with a GPS-based speedometer app in my iPhone. The iPhone and car speedometer were in perfect sync. The camera-indicated speed was indeed extremely low, and so low that I have to think it was made deliberately wrong in order to provide misleading information in court, to fight in jurisdictions where such things are overlooked.

Let's say I was in court for some kind of accident, and I was going 70 MPH in a 60 MPH zone. The video recording of the crash shows the camera says 60 MPH, so it never comes up that I'm partially at fault because I was speeding. The other party in the crash is screwed by faulty evidence.

It is not likely to be cost effective to keep cities open. Clearing snow at a pace that lets you keep the roads open is very costly and hard on the environment. Keeping public transit running is similarly expensive. The cost is productivity for a day but given that these days many people get work done at home the impact of that is somewhat less than it was in the past. We always used to shut down for the worst storms, sometimes the call was made late and people would get stuck. Now the balance has shifted so it makes more economic sense to shut down services for a day to let the snow pass and clear everything out for the next day.

Where did we get the starting pressure from before game time. Were those numbers ever released? Because without knowing what the pressure was when they were first checked you can't possibly know how much the pressure changed making an analysis using PV=nRT basically meaningless.

I do not believe the NFL has released those numbers. Quite possibly because they don't have them because they balls were never actually measured by the refs at the start of the game (They often are not they are only checked visually and by hand).

We have over a foot on the ground already here and it is coming down quickly. We could easily hit 2 feet. I did see a few models that predicted 30-36" but most were saying 2 feet of snow and I think there is a good chance we get to that. Is it the worse blizzard I have ever seen? No. But it is more than enough to close schools, get people off the roads and clear the snow emergency lanes.

I was recently doing 29 and a mobile trap claimed I was doing 35. Fortunately I have video camera evidence from the car to prove that I wasn't, but it means I have to go to court and argue it.

You might want to check your camera before heading into court. I have a gray market cam from that under-reports speed by a wide margin (it displays about 60MPH when my speedometer shows 70); when I use the viewing app they provided, it shows the GPS-plotted path on Google maps, and it shows my true speed.

You want to be sure it's accurate because there is no benefit to you in angering a judge by presenting incorrect evidence.

Me too. It's a hell of a lot harder to bug every man, woman, and child in the west than it is to intercept and crawl their communications. Having them have to actually spend time, effort, and money and risk discovery to obtain information makes it far far less likely that they will collect it just because they are able to. It's a check on their power that's sorely needed.

I came here for this exact sentiment. Spying has always had a component of risk of exposure, and that is needed to keep spying at a small scale. Drift net sieving of all our communications is the abuse.

Actually, with VERY few exceptions, you can run very old userspaces with new kernels. There have been a few 'fixes' that broke old userspaces (by exposing bugs in userspace that weren't triggered pre-fix), but there's a very strict, never break userspace rule. Sometimes you have to set the correct kernel build time options, but it's expected of a person doing that to know what they're doing, or to trust their distro to know what they're doing.

Look at the recent Linux Wireless mailing list... A few weeks ago, the ability to use 'Wireless Extension Compatability' to control wireless was made unselectable. They have been marked deprecated for YEARS(2008), and are now causing problems with supporting newer wifi features. This was very firmly 'NACKED' by Linus, and the wireless tree has to continue supporting an old, broken, way to control wireless devices.

There are also options you can configure in the kernel like 'COMPAT_VDSO' which work around 1 released version of GLIBC (2.3.3), which was also backported to OpenSuse 9.

I know that it may not have been until the 2.6 era that this became truly 'written in stone' law, but it's always been a pretty firm 'rule'. Hence I can still run a.out binaries on my 64bit system. 'ELF' binaries were added around 2.0 (15-20 years ago?), and have been the default since some time between then and now. Still, a.out support will always live on, because you don't break the kernel to userspace abi.

This has been a perpetual problem on my Lenovo W510. In one release, it did multiple steps, in the next one, no backlight control at all. I add some kernel command line options and get a crappy 4 step backlight. In the next release, I have to remove those options because my backlight didn't turn on at all with them. Now no working backlight controls (using the FN+Home/End combo on my laptop keyboard). I poke in the /sys sysfs mount at the backlight control that's registered, and can control the backlight that way. I've been following the ACPI development mailing list and this is a perpetual topic of confrontation.

There are lots of proposed fixes that would just resolve it, but they can't be accepted because they break userspace. The whole problem stems from the Laptop bios. In some cases, the bios will advertise ACPI methods to control the backlight, while the GPU driver exposes the controls as well. Depending on the particular bios version (and sometimes even bios settings), the keypress might, in bios, change the brightness, then report the keypress, or it might report the keypress and depend on the OS to use the ACPI interface to control the backlight, or it might depend on the OS to use the GPU driver interface to control the backlight. On some of the systems, the ACPI interface is sometimes broken, and on some, there are multiple controls (for display port and all the other possible display connections built into the system) with no clear way to determine which one to actually use. Some bioses report to work with 'Windows 2012' but actually completely don't. Some ONLY work with that, but report they work with older ones.

From what I recall of the discussion, Windows 8 deals with this by punting the actual event handling to the GPU drivers, expecting them to know how to handle the hardware.

Similar bugs can be seen in Windows if your run a newer version on hardware designed for a previous version (I saw this running Windows 7 on hardware designed for Windows XP, an old Dell laptop).

I find it kinda crazy that every single other feature of my laptop works perfectly (FIngerprint reader, color calibration, wimax radio {none of which I actually ever use}) while backlight which seems so simple (Press button, change brightness) is in a perpetual state of brokenness.

That's even cooler than I thought. I knew high power radar was responsible for some bird deaths, but they were directly exposed to very high power radiation. I didn't know about the army tech statistics, so thanks! (And would you happen to have a citation to it I could use?)
