Comment Why Thunderbolt? (Score 3, Interesting) 123

Why would you want Thunderbolt again? It is a badly broken (IE doesn't actually do what is promised like channel bonding and a few other things that are sort of fixed in VERY recent silicon), costs far too much, forces the use of painfully expensive active cables, and only passes PCIe or video. This last bit is problematic because if you want any functionality on the other end of the cable, you need to add full controllers there too, think expensive and wasteful of power. In essence you are hot-plugging controllers with the cable, and while it works in theory....

TB is a badly broken spec from day one, it was meant as a control point for Intel to force the use of it's silicon in phones.mobile by replacing USB with something only it could provide. Needless to say the market saw through this and didn't adopt it in droves, sans the few that drank from the Intel money hose. The second the hose was shut off, so was the design wins.

The main reason that USB3 had such a slow start was because Intel was desperate to kill it to promote TB. Since Intel had control over the USB3 cert process, things went might slow for technical minutia that would easily pass by previous spec certs. Coincidence? Nope.

TB is a bad idea on technical, cost, lock-in, and many many other reasons, not working correctly ever being a key one there. Delivered silicon is a joke, there is and always will be one supplier, and progress is glacial. USB3.1 on the other hand beats it like a drum in every regard other than single channel throughput.

Why do I want to pay for this in my next laptop again?

Nobel Laureate and Laser Inventor Charles Townes Passes 73

An anonymous reader writes Charles Hard Townes, a professor emeritus of physics at the University of California, Berkeley, who shared the 1964 Nobel Prize in Physics for invention of the laser and subsequently pioneered the use of lasers in astronomy, died early Tuesday in Oakland. He was 99. "Charlie was a cornerstone of the Space Sciences Laboratory for almost 50 years,” said Stuart Bale, director of the lab and a UC Berkeley professor of physics. “He trained a great number of excellent students in experimental astrophysics and pioneered a program to develop interferometry at short wavelengths. He was a truly inspiring man and a nice guy. We’ll miss him.”

Comment Re:fixing modern gadget (Score 1) 840

But it's usually not those things that actually fail. Most of the random failures on electronics I've seen recently are:

* bad memory modules in computers (trivial to fix)
* bad capacitors (easy to fix)
* linear power regulators breaking their solder joints to the PCB due to heating/cooling (easy to fix)

Although we did have some LCD backlights that failed because as the capacitors started to fail, the power transistor in the DC-DC converter would also go (but it was extremely easy to spot due to the melted hole in the power transistor). We just replaced the LCD backlight DC-DC converter rather than doing any soldering.

It's very rare that some BGA chip is the thing that died in your gadget.

Comment Re: Its a cost decision (Score 1) 840

SMD components are not hard to replace (with the exception of BGA and their ilk). But the usual 0.5mm pitch QFP type stuff, to get the dead one off I use a hot air gun, and to put the new one on, flux, solder, normal soldering iron, solder braid and kapton tape are the tools I use.

Also I design most of my hobby electronics stuff to use SMD. Smaller PCB = lower price for the PCB, and a lot of the interesting chips only come in some SMD package.

What requires incredibly fancy machinery to fix?

While it takes some knowledge to fix a lot of things, fixing for example a faulty washing machine most of the time needs nothing more than basic hand tools and the ability to diagnose what is actually broken, then buying the replacement part.

There are some things that will require fancier stuff to fix, for instance replacing a chip in a BGA package on a circuit board requires specialist tools but a huge number of repairs don't require this kind of thing to be done.

Comment Re:We ARE using ssh and https for everything (Score 2) 203

Unfortunately ftp has far from died. There are so many other organizations I deal with that haven't been hit with the ssh/sftp clue stick and can't do anything other than ftp. Or worse still, ftps which is a firewall administrator's nightmare.

We even deal with one company who not only refuses to use sftp, but they refuse ftp in passive mode and want us to connect to an ftp server of theirs that only supports active mode. Their admin reckons ftp in passive mode is insecure and won't deal with sftp. Sigh. They are of course a Windows-only shop. Most of the companies who are stuck on ftp are Windows shops.

Comment Re:we tried that. Ma Bell, or Boost, Cricket, Spri (Score 1) 221

Actually that model works very well. In many countries the internet provision is better and cheaper with more ISPs to choose from than in the US.

I live on a small island with 80000 inhabitants. We have an incumbent telecom company which owns the last mile, but they must sell that last mile wholesale. As a result, we have not one but four ISPs we can choose from at a decent price, and you can get at least 50Mbit/sec service pretty much everywhere despite the rural spread-out nature of our population.

We don't get the terrible Comcast-only situation many in the US have to deal with.

Comment Patents (Score 0, Troll) 217

Until they stop playing games with hidden and required patents, their talk is just BS. They have shown they have no intent to change that model time and time again, this round is no different. You can open source something that requires a DX call but if you don't open source DX and threaten anyone who does with patent suits, is there a point? It is hollow BS for all the same reasons. Don't buy the PR meant to distract, the underlying mechanics are still the same. They are antagonistic to open source and that won't change at a level deeper than the public messaging.

Comment Re:Here come the certificate flaw deniers....... (Score 1) 80

Signing certificates are normally encrypted. Stealing the file will do no good unless you know the decryption passphrase. For example, to get a package into our local debian repository such that it can install/upgrade in our production environment, you'd not only need the gpg signing keys, but the 60+ character passphrase (which is NOT written down) to go with it.

> Would you want to hire someone who was convicted of violent assault?

It depends why. Were they the initiator of agression, and beat up their spouse? Perhaps not.

Were they defending themselves from a bully? Yes, I would hire them.

A 40 year old who was convicted at age 17 when he flew off the handle for some reason, but has not been in trouble since? Yes, I would hire them.
