Disk areal density: Not a constant, consistent platter

pierce
Coat

Re: Memories ...

first disk drive I worked with had a single platter cartridge of 1 megabyte total capacity on both sides. actually, it was 510,000 words (16 bits each) but that's close enough to 1 MB as what won't matter. This platter was 12 or 14 inches in diameter, and spun at the blinding speed of 1500 RPM, and one of these disk packs held the whole operating system, complete with a FORTRAN compiler, Assembler, and other programming tools.

Trevor contemplates Consumer Netgear gear. BUT does it pass the cat hair test?

pierce
Boffin

my home setup is now a pfSense (freeBSD based) router on a APU1D4 board (10 watts total draw, no fans), whihc is ridiculously overpowered for my 30Mbit cable (and will soon be configured with failover to a static IP ADSL I keep around), FreeNAS (also FreeBSD based) NAS on a HP Microserver N40L (4x3TB disks in raidZ for 7.4TiB usable space), and a UniFi AP-LR ceiling mounted wifi.

I am SO much happier with this setup than my previous old-PC-running-Linux router/fileserver, and various consumer routers-in-WAP-mode doing wifi. Its also greatly lowered my always-on power footprint.

Google Chrome on Windows 'completely unusable', gripe users

pierce

about once ever 3-6 months, I have to purge Chromes cache, then its snappy again for the next few months. history -> clear browsing data.. -> uncheck passwords and form data if you want to keep them, its the browsing history and files you need to clear, and clear 'from the beginning of time'.

Cloud unicorns are extinct so DiData cloud mess was YOUR fault

Facepalm

and by the time you factor in all the redundancy and management required to secure a cloud application, your hypothetical cost savings have gone pooof.

also don't forget to factor in the costs of getting OUT of whatever particular cloud you've chose.

indeed...

indeed, my personal internet server (sharing a friend's coloc bay) is a 2U HP DL180G6 12GB 12 core 2.6ghz SAS machine with 12 3.5" bays I got off fleabay for $740. throw in a couple SSD's for database and software, and a couple SATA drives for bulk storage, and it totally rocks. I host a variety of nonprofit websites and such on this. we paid $7000 for the exact same kit a few years ago at work.

Bash bug flung against NAS boxes

Re: Routers

most of the router firmware I've seen uses busybox's built in minimal shell.

What's a Chromebook good for? How about running PHOTOSHOP?

yeah, this will be SO useful. lets see, I shot 1400 canon raw pics at a festival one 4-day weekend a couple weeks ago, about 50GB worth. If I'd had to upload the raws to the cloud, I'd just about be done by now and could start working on the pictures. oh yeah!

Third patch brings more admin Shellshock for the battered and Bashed

this article says this is the third patch, but its apparently already incorporated in redhat's 2nd patch released last friday....

GNU bash, version 4.1.2(1)-release (x86_64-redhat-linux-gnu)

Fedora gets new partition manager

pierce

Re: Yeah that's what Linux was missing!

WIndows DIsk Management may look easy, but its underying support for raid and volume management are /awful/.

NONE of the existing mainstream linux partition managers are 'good enough'. fdisk and most of its ilk can't handle devices over 2GB due to the limitations of MBR. parted can, but its UI and functionality is *awful*. gparted is just a gui over parted, and has a lot of problems caused by the underpinnings.

really, storage management as a whole under linux is awful. mdraid capabilities should be folded into LVM, so you don't have to deal with all these different layers. look at the way IBM does LVM+JFS in AIX for a big clue.

Microsoft boots 1,500 dodgy apps from the Windows Store

pierce

I've never used a WiPho (heck I don't even use an Android or iPhone, although I do have an android tablet), adn being a staunch desktop user, I can say that the entire 'metro' experience of win8 has done NOTHING for me. I find Win8 quite usable as a desktop system when augumented with Classic Start Menu, but there's absolutely zero of interest to me in that Playskool/Fisher-Price world of lavender and teal blocks and full screen 'apps' that do nothing useful.

Best shot: Coffee - how do you brew?

pierce
Thumb Up

I get my beans from a local wholesale roaster for US$10/lb for the likes of Kenya AA or Tanzania Peaberry (two favorites, both medium roast), as its half the price of the only slightly better beans from either of the two local boutique roasters. We grind them in a Capresso Infinity burr mill to fairly fine, and usually brew in a Bonavita electric drip maker, with a goldfilter. makes a near perfect cup of drip, and the bonavita's thermal carafe keeps it hot for hours without burning it.

the Capresso grinder works surprisingly well for a circa $100 grinder, especially for drip grinds. and its lasted us for many years of daily use.

the aeropress rocks, but we find we use 2-3X more coffee and I end up SO wired I don't sleep well, so its mostly used for camping trips and such. We also have a rather nice little Olympia MaxiMatic espresso maker but that doesn't get much use as its just more work, and I usually drink 2-3 mugs of strong black a day.

US Copyright Office rules that monkeys CAN'T claim copyright over their selfies

if he did any photoshoppery (even sharpening, color balance, contrast), thats a piece of work, which shoudl be copyrightable, even if the original image may not be. so all he has to do is not release the original, just the 'derivative work' he produced, voila, fully copyrightable.

no 'serious' photographer ever releases his negatives.

Top Ten 802.11ac routers: Time for a Wi-Fi makeover?

pierce
Facepalm

yikes, the speed drop off from 1 to 5 meters away on even the best of these is awful. and 30m is even worse, nearly unusable on many of these, and presumably thats not with any walls.

in the 1-5m range, I'll stick with ethernet cables, I do believe. gigE is always 1gb, full duplex, no matter what. and in the 30m range you'd BETTER use ethernet if you want anything done. I've had to run ethernet to both the back bedroom/office rooms in my house as the wifi couldn't possibly reach them through the 5-6 intervening walls and 20m or so distances.

Verizon to limit unlimited 4G plans

pierce
Boffin

there's only so much radio bandwidth possible in a cellular system. if you have 10000 users in an area all streaming 5Mbit/sec videos, thats 50 gigabits/second sustained. there's no way the cellular architecture can cope with that.

they should never have sold "unlimited" service, and encouraged that expectation, it should have been metered from the get-go... use more, pay more. if too many people are using more than you can deliver, jack the prices til the usage drops to manageble levels. use a tiered pricing system so moderate/occasionalusers pay significantly less per unit than data hogs.

AT&T: We will right many of world's wrongs if allowed to slurp DirecTV

ROFL!

"Econometric analysis confirms that, even before efficiencies are considered, the combination of AT&T and DirecTV will create a pro-competitive, integrated bundle of video and broadband services that provokes a beneficial competitive reaction from cable and results in a demonstrable overall net benefit to consumers," AT&T argues.

omg, how could they say that with a straight face??

Google, Red Hat, Ubuntu, Parallels bet on virtualization's surprising successor

the big advantage of containers is much less overhead per VM. with a hypervisor, each VM is running on its own kernel, all of which are talking to virtualized IO devices. with a container (solaris zone, etc), each container is a virtual userspace under the same OS kernel

Canon offers a cloud just for still photos, not anything else. Weird

pierce

I'll stick with smugmug. I tried the various free services, didn't like their albums and/or spamminess. smugmug isn't free, but its cheap enough, offers unlimited storage for a annual fee, and has good looking albums without any restrictions on embedding. Combined with Adobe Lightroom as the photo editing/management tool, it totally rocks, a couple clicks to publish an album, fix a few pics in it later, one click republish.
