Ubuntu To Switch To systemd

zigfreed Car analogy (279 comments)

Init systems are like the starter motor and gear shift of the system. They are not designed to give feedback to the operator since most drivers can hear the clanking and do something about it. SystemD is like the dashboard and steering column with an integrated starter motor. It's got the gear shift built in and some lights that you can sometimes see when you look at it. In essence it is tuned to the motor (kernel) and faster than trying to guess where the clunking is coming from.

You choose systemD because you want the convenience of a dashboard and none of the alternatives considered that part of the design.

AMD Considered GDDR5 For Kaveri, Might Release Eight-Core Variant

zigfreed Obvious questions (120 comments)

Why couldn't this be a package-on-package chip in the current generation? The raspberry pi does this with it's graphics & system RAM; a redesign of the heat spreader and the chip package wiring would allow older motherboards to support it since the new pins come out the top, directly attaching to the GDDR5. Since AMD already sells DDR3 memory, selling GDDR5 with the chip would be business as usual.

Regardless, motherboard manufacturers might still want to integrate the GDDR5 to sell the next generation like they did with sideport memory back when the HD3000 series was integrated in the northbridge.

Third point: since build-your-own computers are commodity devices, traditional layout isn't prohibitively expensive -- splitting the CPU so it's more like a xeon phi and adopting a UMI interconnect is acceptible especially if it could sell on mobile.

Has the Apache Software Foundation Lost Its Way?

zigfreed Re:Apache and OpenOffice (126 comments)

Openoffice needed a home away from Oracle, and the Apache Software Foundation is big enough to host it. Being removed from Oracle, OpenOffice was able to become a combination of Sun StarOffice and IBM Lotus Symphony. At this point in time, LibreOffice and AOO have different licenses - LO is GPL, and AOO is AL.

So What If Yahoo's New Dads Get Less Leave Than Moms?

zigfreed Re:Equal rights (832 comments)

Pay rates are either negotiated per employee or codified indifferent to sex. Benefits being discussed here are codified, are non-medical (this isn't leave due to pregnancy complications), and ignore the fact that the mother (who may not work for Yahoo) may need to get back to work. The argument isn't that men and women are equal, but rather should they have equal opportunity to get things back in order.

Steve Forbes: Bitcoin Not Money

zigfreed Forbes fail (692 comments)

I was hoping to see why it isn't money in the article. He doesn't say. He also didn't read about bitcoin, because he concludes the article with,

"We don’t really know how this coin is created. You can’t have a functional money without a basic transparency."

I remember when journalists actually learned about what they wrote about.

The biggest problem I can see with bitcoin is its value is directly related to its popularity. Where dividend yielding stocks will give you a return in a currency the government will always use, bitcoin's value is always tied into what you can get cashing it out. If it wasn't for bitcoin's strengths (as difficult to exploit, steal, and sieze) and the resilience of the Internet, it wouldn't be as successful as government backed currency.

A mildly amusing conclusion I inferred about bitcoin's design: the same conditions required to break the network (having over 50% of the mining performance) are the same conditions required to devalue the currency (excessive mining and dumping).

GNOME Aiming For Full Wayland Support by Spring 2014

zigfreed This X Forwarding Stuff (300 comments)

I used to do X forwarding, but these days you can remote mount the filesystem in userspace and execute the remote apps locally. The server doesn't have to keep X11 hogging server memory and I get local graphical acceleration. Xorg has features that aren't available in Wayland, and Wayland has a performance advantage because it sheds those features. If it's an old application, X11 is still available. If it's a Wayland-only application, it will have features and performance beyond the limits of X11.

Network transparency of audio was done through PulseAudio (lots of /. complaints in those threads) with ALSA being the lower level component. Wayland (and/or Mir) are heading towards being the lower level component, and network transparency (lets call it PulseVideo) could come later.

FBI Dad's Misadventures With Spyware Exposed School Principal's Child Porn

zigfreed Re:I'm still trying to wrap my brain around... (346 comments)

a lot of OK suggestions, but urandom is slow and not designed for essentially writing junk to disk.

mkpasswd -n 512 | cryptsetup create 0 /dev/sda && badblocks -wst random /dev/mapper/0

1. writes a random, but repeating string to the drive really fast
2. verifies random string which tests disk readability & reliability, but encrypted so the random string doesn't repeat if the drive is read raw.
3. can be done from the livecd, but you have to install expect to get mkpasswd.
4. you can crank up the mkpasswd length, but cryptsetup included in the F18 beta is limited to 512 character passwords.
5. easy enough to remember (mkpasswd, cryptsetup, and badblocks) that you just need to open up another terminal to do the other drives in the system.

i normally start with hdparm's --security-erase-enhanced && --security-disable so I know that the drive started blank, is written to the maximum, and I won't get a disk I'll have to unlock on the next reboot.

France Applies Tax Pressure To Google For Republishing News Snippets

zigfreed Re:Monopoly muscles (350 comments)

Many commenters here oversimplify the problem. Do not forget that Google is in a monopolistic position. Deindexing newspaper web pages could be considered as Google using their monopoly as an advantage.

They would be deindexing at the request of the French legal system, not at the request of management.

The monopolistic position you're referring to is search, which is equivalent to Bing's search (which Bing has the data to show). Continuing with the Bing-Google equivalency hypothesis, adds will be removed from the French news page, creating no ad revenue.

EFF Wants Ubuntu To Disable Online Search By Default

zigfreed Re:Eclipse - the IDE not the movie (124 comments)

This is my experience with dash in 12.10 as well. By default it crams as much useless information in as possible. It posts magazines from the Ubuntu software center before it posts the programs those magazines reference.

I don't mind it searching Amazon, however posting Amazon searches in full view unless entirely disabled is moronic.

Trouble For Microsoft Developers With the Windows Store

zigfreed Re:only 7000 apps? (232 comments)

A credit card processor and a CDN cost a fraction of that. For small usage, PayPal or Google Checkout charge around 3% and you can host the data in Amazon's cloud and get a pretty scalable distribution system for a lot less than Apple charges

And Apple doesn't have Steam weekend sales.

Simple test: go to itunes.com and steampowered.com. Which is going to sell what you have to offer?

Feds Continue To Consider Linux Users Criminals For Watching DVDs

Feds Continue To Consider Linux Users Criminals For Watching DVDs

zigfreed Re:Yay old people! (423 comments)

Why is there now law requiring knowledge and education in the field for which you make and enforce laws?

Because, from a legal standpoint, patents and copyright are really, really boring. Someone understands it; there isn't a market for DVD rippers and the console mod community is pretty black. The downside is this massive barrier to entry on a low damage, personal use item kills any secondary use growth.

Expect Hundreds of Thunderbolt Devices, Says Intel

zigfreed Re:Computer Monitors as an attack vector? (351 comments)

plugging a mouse into your keyboard is very much a non-PC idea

It's a human idea. To the computer, it is plugged into a hub, with one hub port always taken up by the keyboard. For equivalency, a 4 port hub would only add $6 to the cost, and allow you to plug in 1 more device.

Hybrid Car Owners Not Likely To Buy Another Hybrid

zigfreed Re:Because Hybrids Don't Pay For Themselves (998 comments)

Hybrid CNG and electric is greater than the holy grail of fuel efficiency, but you'd have to get a double station: one to compress piped CNG to the auto's tank, and another to charge the battery.

Terahertz CMOS video camera

zigfreed zigfreed writes  |  more than 2 years ago

zigfreed (1441541) writes "From IEMN, STMicroelectronics, and the University of Wuppertal comes a 1024 pixel terahertz camera capable of 25fps. Fabricated on 65nm, it won't give a resolution good enough for the TSA but will allow new applications to be developed in the 0.6 to 1THz range."
