"bird ingestion tests are done with frozen birds" Have you been reading The Onion? This frozen bird thing is a joke, not fact.

They do actually use frozen chickens. After some amount of testing, they discovered that the frozen chickens behave only marginally different from the thawed ones, and by using frozen, they don't have to wait for the chickens to thaw out.

You do realise bird ingestion tests are done with frozen birds right?

Even frozen, pound for pound flesh and bone will do far less damage than aluminum or hardened plastics.

The chickens do massive damage to the engines. The test is not whether the engines survive undamaged, the test is whether they can still function to some limited degree after impact to allow for an emergency landing. In the bad old days, an engine that was struck by a bird would suffer damage in such a way that it would typically ignite and or explode. The result being a plane with a wing on fire, or outright missing. Since these kinds of impacts were determined to be a significant concern, the engines are designed to fail gracefully such that they don't catch fire when multiple fan blades are broken off. The blades themselves are designed to put less stress on the engine when a broken one passes through the engine.

There are plenty of parts on a drone that will behave much differently than a bird, or fan blade when passing through a turbofan. The motors for example are made of high density copper windings coupled with brittle earth magnets. Upon impact with a jet engine, the drone will essentially disintegrate, but the copper windings will tend to pass directly through instead of being deflected by the engines shielding. Like a bullet made out of copper instead of one made out of Jello. The behavior of the permanent magnets is very dangerous as well. Because they are powerful magnets, they will grab onto any metal parts in the engine and can cause some interesting problems. For example, if even a relatively small amount of magnetic dust makes it into one of the precision bearings, it will cause accelerated wear, and if there is enough it will cause extreme heating or vibration, either of which could completely destroy a jet engine. There are lots of failure modes that a drone strike can trigger that a bird strike simply cant.

Yeah, because nobody in the world had ever heard of Facebook. You really believe that crap you spouted? It makes me ill to have to defend them, but if I want a job at Facebook I think I might, you know, look for job postings at Facebook. I'm pretty sure I know how to find them.

If you're looking for a job, you're going to go look where jobs are posted. You generally will not go down the phone book looking for companies that are hiring and visit their website to find out what positions they have open. More often, a candidate will find an opening, that is not published on a jobs site, by way of a friend who works there. As the GP stated, this is a self selecting group, and will *absolutely* result in a lack of diversity. The only way to counter this is to suck it up, post the job on one of the job sites, and deal with the fact that you will get 50k - 100k resumes. Diversity costs money, and if the company is too cheap to pay the $$$ it costs to search for candidates, the right way, then they should not be at all surprised to discover their search results were lacking in one or more ways.

While it is a shortcoming of the education system, it's not because of money. We spend more than ever per student. The problem is government schools.

Then why is it that government schools in almost every other nation are providing better education than we see here in the states. The problem is *not* government nor is it business, it is societies views towards education and intelligence. There is a very strong anti-intelligence viewpoint in this country. This effect had seemed to be dwindling during the 50's and 60's with the advent of NASA, and the very clear results that science and technology could produce that stupidity could not. Today we are seeing a fundamental shift the other direction. The median American sees intelligence as something to be distrusted. Compare that to German, Japanese or Chinese culture where intelligence is recognized and prized, and you have all the information you need to explain the failings of the American education system. As harsh as it sounds, the reality is that the idiots are simply out breeding the intelligent people in this country, and for some reason our society seems to be quite content with that, in fact we have given celebrity status to the duggars because of their willingness to produce far more offspring than they can support, and then release them on the world with a piss poor education, consisting of only their siblings and cameras for teachers.

That DC10 was designed to hit geese without sustaining damage. You think a 1 kg drone is going to do anything?

No, the DC10 is designed to not crash after hitting a goose. They make no claims about damage. After a typical bird strike, the plane will still fly, but after it lands they're going to need to spend a few weeks rebuilding the engine that got hit.

Drones are a bit more harsh on the engine, because geese are made of relatively soft stuff. Even the bones are remarkably flexible. The metal or plastic chassis of a drone on the other hand is actually designed to be very rigid. I would not be surprised in an engine, that survives a goose strike relatively intact, is completely destroyed by a medium sized drone.

You give the verbal offer and *then* do the background & reference checks?

Thats pretty normal. The offer is contingent upon favorable results of the various checks. It allows the hiring company to keep an applicant from straying, without having to commit the resources to the checks until after you know the employee will accept the position.

Comment: Re:The problem is broken updates (Score 1) 289 289

Then Samsung should make sure the drivers they supply to Microsoft work. Samsung holds the reins here. Microsoft can't help it if Samsung's drivers break stuff. If Samsung haven't provided their own drivers to be included in Windows Update, then that's their fault. If it is Microsoft's fault, why does this work flawlessly for all other manufacturers, and indeed Samsung until this incident?

First, this doesn't work flawlessly for other manufacturers. The problem is chipsets. When manufacturers are designing their products, they have to choose the chips that will go into those devices. Typically they will try to pick the least expensive and easiest to support devices, but this process begins at least 6 months (often far longer) before the product comes out. These chips normally have ways to identify themselves, and often times, one OEMs drivers will actually work with multiple OEMs products because of these basic chipsets. Not only that, but if one of those OEMs is sloppy about how they design their product, their drivers could mistakenly identify other products and install drivers for them that might not be 100% compatible. You tend to see that a lot with cheap printers. At the end of the day, it can happen that through no fault of anybody specific, the wrong driver will be identified and installed by an update. In reality, its Microsofts fault, as they should *never* allow driver updates without a user specifically requesting it, but here we are...

Having each manufacturer design their own chipsets would needlessly increase the costs for products and would provide very little advantage for anybody. Most chip design houses these days, try to duck the problem by providing generic driver themselves and will provide a reference design that will work with those drivers. That way anyone who uses that chipset and sticks to compatible variations on the reference design will enjoy less driver compatibility issues. The biggest hazzard is being the first one into the field with a product, as you bear the brunt of the compatibility problems without the benefit of hindsight.

Where I work, we had used exclusively freescale processors. The founder of the company had used them in school, and was unwilling to even consider alternatives. About 5 years ago, they had a massive product flop as a result, and he stepped away from daily involvement in the company. Since then, we have been dropping freescale as fast as we can design away from their processors.

Recently that process has been accelerated because freescale EOL'd the most frequently used processor, and with no pin-compatible part, it is worth our time to simply switch away from them as fast as we can now. We're going with the Cypress PSOC series. The dev environment is excellent, and some of the 5 series processors have so much stuff in them we have been able to reduce our parts count by half or better. They're also vastly cheaper than the freescale processors, which makes us conclude that the companies founders got where they are more by luck than skill.

Bottom line? I'd recommend Freescale 9 times out of 10 for any of the medium to small players if I was looking for a high end ARM SOC.

They'd be an idiot to listen to you. Freescale chips are more expensive, and less capable than almost every other player out there. They've been riding on inertia for the last ten years. They haven't done much by way of improvements in that time, their flagship development environment hasn't changed (not even bug fixes), and to boot they are the only chip vendor left who charges for their dev environment. If you want GHz+ processors for cheap, you want Broadcom. if you want SOC and / or large numbers of I/O, you want cypress. if you want both, you can buy both for less than the cost of the freescale chips, come out way ahead in development time, and have fewer problems with your PCBs being manufactured. In short, there is no compelling reason to even consider the MX7 series, and lots of reasons to dismiss freescale out of hand.

Freescale end-of-lifed the processors we used to use (in and of itself a bad sign). When we looked at the replacements, the freescale options were 2x-3x more expensive, availability was questionable, and freescale refused to make any lifecycle promises (as opposed to atmel and ST who both promised 15 years, and Cypress who haven't EOL'd a single processor without providing a pin-compatible replacement.

To add insult to injury, the Freescale dev tools (code warrior) cost big $$$ in yearly license fees, and they are buggy as hell. Their compiler still does some wickedly hokey shit. I can compile the exact same code on the same machine twice, and one compile works, while the other one fails. We had a license expire and instead of giving us a simple "Your license is expired" error, it gave us a never ending stream of cryptic errors. It took our IT guys a week on the phone with support to find out that the license was expired. even the codewarrior people were stumped at first...

At the end of the day, go with Cypress. you'll be happier in the short run and in 5 years you wont be scrambling to redesign your products because freescale EOL'd your processor on you without providing a pin-compatible replacement...

Very true, but Ms has a long history of failing to anticipate important consequences of their actions. The one I foresee with this is that with millions of extra users testing the OS in a "beta" state, they will see it at its less-than-finest. You can argue all you want to that its a beta, but first impressions count. If the beta isnt very close to fully stable, then they will leave a bad taste in peoples mouths. With early adopters, thats not really a big deal as they expect it. With people now signing up just to get the free license, you get end users who get to experience a beta environment, and they wont like it.
