Microsoft CEO To Slash 18,000 Jobs, 12,500 From Nokia To Go

jcdr Re:Nokia sure has bad luck (383 comments)

There exists a more cynical possibility: some entities could have buy enough share to impose key members into the board, fully knowing how the story will end. The cost of destroying Nokia could have be lower than the risk of losing others long term investments of the same entities.

Microsoft CEO To Slash 18,000 Jobs, 12,500 From Nokia To Go

jcdr Re:Nokia sure has bad luck (383 comments)

Very true. How the board was misinformed to the point of doing a such clear suicide is still part of the hidden story. Even more strange is the constant support the board give to the CEO even after all the alarms was turning full red. The "No plan B" concept was the biggest mistake ever from a board.

Ask Slashdot: Best Dedicated Low Power Embedded Dev System Choice?

jcdr Atmel SAMA5D3x (183 comments)

This is a new chip with a ARM Cortex-A5 core, making it directly compatible with all distributions with an 'armhf' port like Debian, Ubuntu or Linaro.I like the fact that it is compatible with the Arduino Due connector. It's probably the easiest Linux based Arduino hardware compatible board.

The AI Boss That Deploys Hong Kong's Subway Engineers

jcdr HAL9000 is not so distant (162 comments)

"I've just picked up a fault in the AE35 unit. It's going to go 100% failure in 72 hours."

"From its omniscient view it can see chances to combine work and share resources that no human could."

The fiction in the movie "2001: A Space Odyssey" is maybe to believe that the human brain could ever compete with a computer.

4K Monitors: Not Now, But Soon

jcdr AMD A10-7850K - DP - Samsung S28D590D (186 comments)

I just buy this setup last week and it work perfectly well at 3840 x 2160 @ 60 Hz with Debian Jessie and the last fglrx-14.20 driver. The monitor is packed with a DP cable (and a HDMI cable by the way) so it worked out of the box with a FM2A88X Extreme6+ motherboard. I have see 30 Hz display before, but sorry, I can't enjoy them to test 1080p60 applications in a window while having code and debug around others windows.

Electronics schematic and hardware routing is a pleasure on UDH monitor, as coding side by side to the full documentations and output results. On the fun side, Google Earth is probably the most impressive with so much details that it's a bit like an immersion. The APU is still capable by itself to yield a few frames per second in full screen mode. Really need a powerful GPU if you expect more...

The monitor have a little bug in the power management that require to cycle his power to sometime weak it up, but this is a minor issue for me.

Cisco Opposes Net Neutrality

jcdr Don't change the definition of the Internet. (337 comments)

Of course there is requirements for networks with different features compared to the current Internet, Cisco just have to realize that it can't call them 'Internet'.

'Internet' precisely define a relatively cheap to operate neutral network that don't grant performance. Anyone can use it like it want to as long at it contribute to it and don't cause problem to the others participants. This fact have a lot of implication on how the network is managed and how it is sustainable financially.

It's right that the internet is not the best network for a categories of uses cases that need granted performances. This is a justification to build a other better network that fit the expected requirement. Call it 'Servicenet' of you wants. But this not a justification the fight against the net neutrality of the Internet.

Ford's Bringing Adaptive Steering To the Masses

The Toyota Prius have it at least since the Prius II from 2003. Now that depend how much you think this is a common car model...

Ford's Bringing Adaptive Steering To the Masses

jcdr Re:Ghost in the machine (128 comments)

This is old news: this system is already used on some cars since many years. Toyota for example have it at least since the 10 years old Prius II.
And now think about the driverless Google car...

Autonomous Car Ethics: If a Crash Is Unavoidable, What Does It Hit?

jcdr Re:Screw other people (800 comments)

Take the question in a other way: if the car is autonomous there is no driver anymore, so in case of inevitable fatality (maybe no involving an other car at all), who will likely die in the car, depending of the last car action ?

Autonomous Car Ethics: If a Crash Is Unavoidable, What Does It Hit?

jcdr Re:A bunch of nuns? (800 comments)

Ok, but the problem is that you will maybe not known in advance that you are in a car that is programmed with this feature.
You might be in a car owned by an other, in a taxi, in a bus, etc...

USB Reversable Cable Images Emerge

jcdr Re:Power delivery is good at data transmission. (208 comments)

I remember having build and used perfectly working small RF transmission devices with 27 MHz frequency. There never required a 3.5 or 14 meter long antenna !

USB Reversable Cable Images Emerge

jcdr Power delivery is good at data transmission. (208 comments)

From page 18 of this document: https://intel.activeevents.com...

"The PD communication channel is an RF system:
- 23.2 MHz DFSK with a nominal deviation of 500kHz"

So the VBUS/GND pair alone can be enough to transmit data than USB LS (1 Mbps) and USB FS (12 Mbps). I see this a a very interesting solution: a standard to deliver negotiated power and mid range data rate using only 2 wires. If only the USB PD will allow a broadcast topology, I see a lot of possible applications...

The frequency of the power delivery is so high that an antenna could maybe be enough to transmit wireless data, without power. LOL

USB Reversable Cable Images Emerge

jcdr Re:Reversible (208 comments)

The same document in page 14 limits the 60W and 100W profiles to the A and B type. So the C type is probably limited to 36W.

Bug In the GnuTLS Library Leaves Many OSs and Apps At Risk

jcdr Re:Concur. (231 comments)

Sorry, you don't use the right command to see the reverse dependencies.

Try this:
apt-cache rdepends libgnutls26

I will not post the result here, because it's 494 lines long on my system:

apt-cache rdepends libgnutls26 | wc -l
494

Background Javascript Compilation Boosts Chrome Performance

jcdr Re:In node.js too ? (136 comments)

I don't pretend that Nodejs is comparable to Tomcat or similar options. I just noted that restarting on an uncaught exception, while not included in the Nodejs environment, is technically nothing special in Javascript virtual machine compared to others language. I have do that with a manager application or script in many projects. I will probably try to use systemd to do that in the future.

Agree on that. Replace it by Javascript virtual machine in my previous text.
This is the same relation than with Java and his virtual machines implementations:

Will Microsoft IIS overtake Apache web server ?

jcdr jcdr writes  |  about 6 months ago

jcdr (178250) writes "February 2014 Web Server Survey by Netcraft show a massive increase of Microsoft web server since 2013. Microsoft's market share is now only 5.4 percentage points lower than Apache's, which is the closest it has ever been. If recent trends continue, Microsoft could overtake Apache within the next few months, ending Apache's 17+ year reign as the most common web server."

Which phone has a USB powered host mode ?

jcdr jcdr writes  |  more than 4 years ago

jcdr (178250) writes "More and more mobile phones have a USB port capable of operating in host mode. But very few of them are capable of powering a USB device by themselves, without using another power source. The problem is complicated by the fact that manufacturers rarely provide the exact specification of the USB host mode. This makes it not easy to find a phone that can power a device, and buying all the possible candidates would be extremely expensive, not including the time for testing. I'm looking for experiments to find out which mobile phones currently available for sale have been shown capable of powering a USB device that consumes less than 100mA current."
