Linux 3.8 Released

blitzkrieg3 F2FS is not for SSDs (120 comments)

It's actually a new filesystem for flash storage, which is cheap storage that does not have a controller to do wear leveling and other things. SSDs have firmware that are optimized for traditional filesystems such as ext4.

Do Not Track Ineffective and Dangerous, Says Researcher

blitzkrieg3 Killer 'Do Not Track' App? (207 comments)

I seem to remember the imputus for this stupid technology was that a Mozilla researcher was about to make available some technology that either blocked tracking cookies or made them relatively anonymous, but then Google and others stepped in and stopped it, and came up with this easily ignorable solution instead. Has anyone else heard of this or am I making it up? Since the story first broke I haven't been able to find any references to it.

How Would You Redesign the TLD Hierarchy?

Apple Denied Trademark For 'Multi-Touch'

blitzkrieg3 Re:There should be some penalties... (217 comments)

This page is using the term "multitouch" a full year earlier. And even if Apple were the first to use the term, they didn't trademark it before it became a more generic term, used on synaptics touchpads as mentioned.

The Real Truth About Oracle's 'New' Kernel

blitzkrieg3 Re:But how is this not fraud? (177 comments)

It's possible they went with 2.6.32 because they hope it will be ABI compatible with the RHEL 6 kernel.

The Real Truth About Oracle's 'New' Kernel

blitzkrieg3 Re:But how is this not fraud? (177 comments)

Full Disclosure: I work for Red Hat, but these opinions are my own and not representative of RHT.

The Kernel is the only thing in there that ISN'T from RedHat

This is wildly misleading. Almost everything Red Hat ships in Enterprise Linux is not from Red Hat. Projects like GCC, RPM package manager, Gnome, Glibc, KDE are all too big for Red Hat to develop on its own. The only things I can think of that are completely from Red Hat are layered products like Directory Server or projects where Red Hat has maintainership and majority contributions, like NetworkManager.

Having said that, I can't think of a kernel contribution report in recent years where Red Hat was not #1.

Apparently to call it a "new" kernel TFA feels they should have started entirely from scratch.

To call it a "new" kernel it has to be something less than nine months old.

The Real Truth About Oracle's 'New' Kernel

blitzkrieg3 Re:Uhh, isn't this what Oracle customers pay for? (177 comments)

"Fine tuning" could be anything from tweaking some compiler settings to actually patching things in the kernel.

They patched quite a few things, but at the same time thought it important to be as close to mainline as possible. Here's the lowdown from Chris Mason over at LWN:

Hi everyone,

One of the goals of this kernel was to stay as close to 2.6.32.stable as we could. The sources are here in git, they won't be rebased:

http://oss.oracle.com/git/?p=linux-2.6-unbreakable.git;a=...
git://oss.oracle.com/git/linux-2.6-unbreakable.git
The main differences from mainline:

*) semtimedop optimizations. I posted these to the list a while ago, and Manfred took things in a less complex direction. He was waiting for me to fully benchmark the less complex version, but we ran out of time in the release cycle and had to focus on other things. Oracle hammers on the IPC lock, so these made a big difference, and now I finally have time to properly benchmark his approach against mine.

*) Ocfs2
*) Small lock contention fixes
*) Receive packet steering
*) A large update to RDS (this is in a different package)
*) A patch to list msi irqs for each device in sysfs. A modified irqbalance uses this to keep irqs on numa local cpus.

There are other bits and pieces, but we resisted the urge to pile things in.

The solid state disk access number came on a huge machine, and the improvements came from getting rid a lock in the driver and enabling it for softirq affinity code without taking any of the request locks.

Over the next 12 months we'll be getting an update prepared to a new mainline version, and trying to hammer on upstream kernels as much as we can to reduce our patch count even more.

Why Overheard Cell Phone Chats Are Annoying

blitzkrieg3 interesting research (344 comments)

I was just talking about this with my friend yesterday. She said that someone on the bus just looks over at a woman on her cell phone, and that another rider gave her the dirtiest look until he spoke up and said, 'please put away your cell phone' My friend thought the guy was rude, but I thought he was justified. Cell phones seriously irritate me. That's one good thing about riding the subway.

Red Hat Prevails Against Patent Troll Acacia

blitzkrieg3 Re:Epic patent trolls? (89 comments)

I'm pretty sure they got the patent from Xerox, for rooms. The idea was that you use a room and house analogy for your window manager. So all offices applications are in the office room, games in the gaming room, recipes belong in the kitchen, etc. And you had to switch rooms via a door icon, no joke.

Red Hat Releases RHEL 6 Public Beta 1

blitzkrieg3 Re:which fedora? (148 comments)

It's a very fast moving tree. For example, I'm running 2.6.32 on F12 right now even though it shipped with .31. The .32 kernel just happens to be the release that balances the need for test enough with the latest release out of kernel.org.

Cox Discontinues Usenet, Starting In June

blitzkrieg3 They should get rid of email too (306 comments)

Exactly! I'm reminded of this post by email researcher Meng Weng Wong, where he talks about DSL and providing good email service:

DSL providers should just say to their customers, we'll just drop your price by $X a month if you decline POP --- that way we save on machines, sysadmins, and software licensing fees, and we get to say we're 20% cheaper than the competition ... and you'll just go off and use Hotmail, which is what you were going to do anyway!

Maybe they'd use gmail instead of hotmail today, but the same principal applies.

Net Neutrality Suffers Major Setback

blitzkrieg3 Re:FCC Got bit by it's own Teeth. (790 comments)

The parent article also mentions that ruling. But aside from that, what makes you think that the FCC is going to lobby for broadband deregulation in the future? If anything, they're going to fight for broadband regulation now that they've realized they've created a monster. I expect in the future broadband will be more heavily regulated, and Comcast will file this incident under, "Lessons on biting the hand that feeds."

Net Neutrality Suffers Major Setback

blitzkrieg3 Re:Did you hear that? (790 comments)

Good thing Comcast doesn't operate across state lines!

But seriously, broadband access is already "lightly regulated" by the FCC. All they need to do is go to congress and get that changed to "heavily regulated" and then they can continue with their net-neutrality laws, despite what the Constitution says.

Net Neutrality Suffers Major Setback

blitzkrieg3 Re:Meme (790 comments)

Indeed, it is the case that "they don't have common carrier status." This is explicitly mentioned in the article:

The cable company had also argued that the FCC lacks authority to mandate Net neutrality because it deregulated broadband. The FCC now defines broadband as a lightly regulated information service. That means it is not subject to the obligations traditional telecommunications services have to share their networks with competitors and treat all traffic equally.

The best part is that the decision may cause "the agency [to] simply reclassify broadband as a more heavily regulated telecommuniciations service." In that respect, Comcast has dug its own grave, as well as those of several others, Time Warner, Cablevision, Verizon to name a few.

Laptops in the classroom don't increase grades

blitzkrieg3 blitzkrieg3 writes  |  more than 2 years ago

blitzkrieg3 (995849) writes "Classrooms all around the country are being fitted with one to one laptop programs, networking hardware, digital projectors, and other technology in order to stay competitive in the 21st century. Kyrene school district spent $3 million modernizing their classrooms. The problem? The increase in spending doesn't lead to an increase in test scores. Policy makers calling for high tech classrooms, including former execs from HP, Apple, and the Bill and Melinda Gates Foundation, want to increase technology investment despite the results. Others are not so sure, or think it is an outright waste of money."

iPad and the Cloud Increase Your Carbon Footprint

blitzkrieg3 blitzkrieg3 writes  |  more than 3 years ago

blitzkrieg3 (995849) writes "A common advatage advantage cited for cloud computing is energy savings, through the use of technologies like geothermal energy, sea water cooling, virtualization, and smart stretch clusters. Then why is Greenpeace, on the eve of the iPad release, worried about energy consumption in the cloud? They report that datacenters will account for 1,963 billion kilowatt hours of electricity in 2020, a 3 fold increase. And a lot of this energy will come from coal, such as the new datacenter Facebook is building in Prineville, Oregon."

Microsoft’s Creative Destruction

blitzkrieg3 blitzkrieg3 writes  |  more than 4 years ago

blitzkrieg3 (995849) writes "Dick Brass, a former Microsoft Vice President, penned a scathing critique of the corporate culture at Microsoft in a New York Times Op-Ed today. Internal power struggles kept technologies like ClearType and the Windows tablet from becoming revolutionary products. He writes:

Internal competition is common at great companies. It can be wisely encouraged to force ideas to compete. The problem comes when the competition becomes uncontrolled and destructive. At Microsoft, it has created a dysfunctional corporate culture in which the big established groups are allowed to prey upon emerging teams, belittle their efforts, compete unfairly against them for resources, and over time hector them out of existence.

In 2010 the World Runs Out Of IPv4 Addresses

blitzkrieg3 blitzkrieg3 writes  |  more than 4 years ago

blitzkrieg3 (995849) writes "Ars has an excellent writeup of the coming end of the IPv4 Address space, as well as in depth technical reasoning behind it. From the article:

Either by choice or otherwise, the big ISPs will soon have to stop giving each customer an IPv4 address of his or her own. Giving those customers just IPv6 is not an option, as the majority of the services are still IPv4-only and many IP-capable devices that don't run a full operating system (smartphones, VoIP phones, webcams) don't support IPv6. So that means stretching the existing IPv4 addresses in some way through "carrier grade NAT" (CGN).

Assuming the ISPs don't strip people of their current IPv4 address, Apple users may be in the best shape."

Sears.com Squelches Web Programming Blunder

Sears was storing page paramaters from the client editable url into the catagory of the page, leading to some pretty funny results. Once the catagories were loaded into the cache, every subsequent hit would pull up the same user submitted catagories, even without any page paramaters. TMZ and Fox News have their own reports. Reddit has since been forced to take the post off of their front page by their parent Conde Nast, but the page can still be accessed via permalink."

"Nothing Left to Prove" on The Linux Deskt

blitzkrieg3 blitzkrieg3 writes  |  more than 5 years ago

blitzkrieg3 (995849) writes "Matt Asay likes the latest Fedora release, especially when it comes to the desktop. From the article:

This is the state of "desktop" Linux today: it really has nothing left to prove. It took years to become user friendly, but it has arrived, helped along by the world's move to browser-based computing. At this point, the only thing that Fedora and the other Linux distributions can do is embrace and extend the Windows or Mac computing experience, because they've largely matched them (especially Windows).

I'm impressed with the work on xrandr and HAL, particularly with regard to input properties. Devices can now be hotplugged without major issues, and most new distros are having users delete their xorg.conf."

An unnamed spokesperson for Danger Mouse says that "due to an ongoing dispute with EMI" the book of photographs will "now come with a blank, recordable CD-R. All copies will be clearly labeled: 'For legal reasons, enclosed CD-R contains no music. Use it as you will.'"

NPR Music is also streaming the entire record, completly for free. Danger Mouse has previously entered questionable legal teritory with The Grey Album, a mashup of Jay-Z's Black Album and The Beatles White Album. EMI also blocked the release of that album."

General Motors Snubs Battery Exchange Model

blitzkrieg3 blitzkrieg3 writes  |  more than 5 years ago

blitzkrieg3 (995849) writes "Better Place, the electric vehicle company that partnered with Israel, Denmark, San Fransisco, Austraila, and recently Hawaii to install electric vehicle grids, is also working with automakers Renault and Nissan to produce electric vehicles that will accept their standardized batteries. General Motors was also asked to participate, but declined. Thomas L. Friedman argues it's because of such short-signed decisions and general lack of innovation that the big three are having to ask Congress for $15 billion. The business model that Better Place is pioneering has the potential to revolutionize the auto industry as we know it, possibly killing the gasoline car in the process. Did GM make a mistake by not becoming a partner?"

We don't want to be closely aligned with proprietary Unix. No offense to HP-UX, but we feel the same way about [IBM's] AIX, and we feel the same way to some extent about Solaris
Other reasons cited for the switch were increased flexibility and lower cost."
