Satellite Images Show Russians Shelling Ukraine

Lawrence_Bird Taking them at face value eh? (298 comments)

At least by the headline it seems so. I took a look this morning at two of them and you can clearly see some areas in the "pre" that had "bomb craters" just as the purported second "post" image. Also notice differences in resolution.

These images - just like anything the Russians or Ukranians give - should not be taken at face value.

AP Computer Science Test Takers Up 8,000; Pass Rate Down 6.8%

Lawrence_Bird AP is a scam (117 comments)

these classes are not equivalent to a college class and have been debunked often. You want to show you know how to program on your college application? LIst the apps you have created for Android/iOS. List your involvement in open source projects.

Any student considering AP (anything) would do better to take a summer class at the local community (or better) college. Calc, physics, etc... Get an A and you can probably a) transfer the credit and b) do better in the next class

Lawrence Krauss: Congress Is Trying To Defund Scientists At Energy Department

Finally off the government dole. Let private industry develop the technologies. If there really is a market they will exploit it better than our wonderfully efficient government does.

China Plans Particle Colliders That Would Dwarf CERN's LHC

Lawrence_Bird Re:Good luck with that (217 comments)

I doubt that China could build the magnets in use now at LHC on their own and certainly you will need at least that much for a super proton/proton collider.

Can you really compare the sophistication/complexity of Atlas/CMS or even D0/CDF to neutrino dectors?

Does China have the systems capabilities to handle the data output of these types of experiments?

The biggest problem China faces is they are not likely to get much help from western governments due to the technology transfer aspects.

China Plans Particle Colliders That Would Dwarf CERN's LHC

Lawrence_Bird Good luck with that (217 comments)

LEP operated around 209 GeV in 27Km so this Chinese proposal of 240 GeV at 52Km is.. underwhelming. Realize things like labor cost less in China but this isn't a high rise they are making. LHC cost amost $5B to build. Where is China getting the magnets? I'm not sure US export controls will allow a sale. And then there are those pesky detectors which are technological marvels themselves.

Still unfortunate that we can't scale up anti-proton production to levels necessary for high luminosity.

Malaysian Passenger Plane Reportedly Shot Down Over Ukraine

Lawrence_Bird Re:Why fly over a war zone? (752 comments)

er no, I am saying primary fault is with the airline. secondary "fault" are the combatants. If you, as a civilian, go into a known war zone and then are shot (intentionally or not) the primary blame is with you for going where you clearly should not be. That you perceived the area of the war zone you were traversing to be "safe" is immaterial. You went into a warzone, you take the risk of death.

I have heard some on the news say that the plane was rerouted because of "weather". Again, there were many other rerouting choices which would not include flying through this region but they all probably cost a few bucks more. And it is not like a tornado suddenly emerged, this was a large weather system and known prior to departure.

Sorry, this is an airline risk management fail first and foremost. Arguing that combatants (and probably poorly trained ones) should know the difference between an AN-26 and a commercial jet misses the point.

Malaysian Passenger Plane Reportedly Shot Down Over Ukraine

Lawrence_Bird Re:Why fly over a war zone? (752 comments)

Planes have already been shot down as part of the hostilities. To assume that because your commercial flight is flying higher than those it can't possibly be targeted is the height of stupidity. Likewise falling back on the 'well, Ukraine never closed their airpsace'. Just because a road is open does not make it wise to take it.

I'm sure flying over Ukraine is a cheaper route for the airlines. Until something bad happens and your bird drops. This is all about a failure of risk management. It is one thing if your final destination is in/near the hostilities. Then you make a decision if you are going to fly that route, well thats the only way to go and everyone knows whats what before you start. But to do a fly over when you can easily route around it (even within Urkraine) is stupid.

US Marines Demonstrate Ultra Heavy-Lift Amphibious Connector Prototype

Lawrence_Bird Re:Another boondoggle (90 comments)

Kuwait: bombing went on for a month prior to that. Grenada: Operations were already well underway before a small Marine amphibious landing

Few landings of Marines happen in contested zones and one of the only reaons they continue to try to build things like this is the ego of the Marine's who feel without the amphibious capability they are just Army. Rather than think of better ways of delivering equipment they just try to make a new spin on an old story.

Malaysian Passenger Plane Reportedly Shot Down Over Ukraine

Lawrence_Bird Why fly over a war zone? (752 comments)

Is it really a good idea to continue flying your normal route when it now goes over a war zone? And one where planes and helis have already been downed? Its not like there aren't any number of safer alternatives.

Take the same chart from Forbes that goes back to 1900. Cut 1995- present and insert in the middle of the series. Do you still see a trend? Or do you just see a lot of noise around the median?

Plummeting BDP on High Speed Lines

Lawrence_Bird Lawrence_Bird writes  |  more than 2 years ago

Lawrence_Bird (67278) writes "In trying to track down a tcp problem today I've stumbled upon what seems to be a nasty little issue — incredibly low ping times!

I have a 25Mbps line and in checking RTT to places I frequent, I found that the times are tanking. Not that long ago, a fast link was like 60ms with most around 90-120ms, twice that overseas. Now many are coming in the 45-80ms range. But quite a few others, like youtube (6ms) google (7.5ms), apple (15ms) cbs.com (20ms) slashdot (30ms) , are a lot shorter.

This presents a very difficult problem. How to best tune RWIN? The rule of thumb had been to make rwin just greater than your typical BDP and most information on the topic is written at a time when high speed lines were starting to appear but latency was still high (>100ms). But now we have a situation where yes, rated speeds are high, but latency has dived to next to nothing for major internet sites but may still be high(er) elsewhere creating not a 2 or 3 to 1 range of RTTs but instead as high as 25 or 30x!

To optimize for google would require setting it to under 24,000 bytes. In fact, any average ping time below 48ms will (I think) saturate if RWIN is over 65,535 (the point at which scaling would take over). Yet there are still a goodly number of places that are over 80ms (say stanford.edu) and of course europe and asia can be 200ms.

So I am curious what others are doing to tune RWIN to provide the necessary throughput on the longer latency runs against these now incredibly short pings"

Ron Paul Raises More Than $3M Online in 18 hours

Lawrence_Bird Lawrence_Bird writes  |  more than 6 years ago

Lawrence_Bird (67278) writes "Republican Presidential candidate has raised in excess of $3 million since midnight. Grassroots supporters organized a 'money bomb' campaign for 5 November — Guy Fawkes day (remember, remember the 5th of Novemeber). At about 5:50pm EST, the total passed the $3 mio mark and is on a pace for over $4 mio by midnight. The NY Times political blog has more details."

Ron Paul More Cash On Hand Than McCain

Lawrence_Bird Lawrence_Bird writes  |  about 7 years ago

Lawrence_Bird (67278) writes "Longshot Republican presidential hopeful and internet phenom Ron Paul (TX-14) reported today his campaign has more cash on hand ($2.4M) than does John McCain ($2M) and only slightly less than Mitt Romney ($3M excluding his personal loans). Paul's spokesman noted(nytimes) that most of the donations were via the internet and that Paul is able to run a much more frugal campaign (he has only 11 staffers) because of his wide spread support via sites such as youtube and meetup. The campaign was also the first to provide an iPhone specific platform to allow access to campaign materials."
