Are Consumer Hard Drives Headed Into History?

temojen False Dichotomy (681 comments)

This entire "debate" is rediculous anyways.

SSDs are good at being fast and surviving being dropped. HDDs are good at being cheap per GB. Both have their place. There is no reason you can't have both in (or for use with) the same system.

I work at a small-market IT subcontractor where we do project and break-fix work for a huge variety of businesses and hardware manufacturers.

Out there in the real world very few large businesses use over 40~80GB on the primary hard drives of end-user desktops or point of sale, despite the fact that they all come with at least 500GB. Anything other than the OS and applications and current user's profile really should live on the network somewhere. That somewhere is probably on a spinning platter.

SMBs often will have a lot of data on each desktop HDD, but they really should have a workgroup server to do centralized authentication (domain|LDAP), email (exchange|IMAP), user (profiles|homedirs), fileshares and centralized backup as very few have any organized way to recover from loss or damage of one or more workstation. Most users need very little space; Executive, secretary, accounting, medical office data, etc all is small and should really be on a server. Some applications (ie CAD, GIS, medical imaging, media editing, etc) do require large local fast storage, but this can be handled by having two drives: 1 SSD and one or more HDD in the few workstations that need it.

Home users can easily have more than that much on their desktop or laptop, but there's no reason their computer can't have 1 SSD and 1 or more HDDs be they internal, external, or NAS.

Small Startup Prevails In Server Cooling 'Chill Off'

Or desktops with heatpipe based heatsinks... Tiny laptop fans can get pretty loud. With much bigger dissipation surface an overclockig heatsink on a low power CPU can spend most of it's time with the fan off.

Happy 17th Birthday, Debian!

temojen Wrong about one of those (225 comments)

Windows NT was first released in 1993, making it the same age as Debian. Before NT, windows was a user interface on top of DOS, not an OS on it's own (although it was doing VM as of 3.1 and networking as of 3.11, but not it's own filesystem management).

Using GIMP for real-world print jobs?

temojen What? 1995? (1 comments)

Why is the printer asking for 4 colour seps and not just a normal PDF? Did they give you a profile of the exact ink and paper combination they are using? Most print houses do this for you now (in fact many don't do a seperate step, it is done by their software automatically). (yes, I do understand that you are talking about offset, not laser printing)

Open Source Geographic Tracking?

temojen Good luck with that. (84 comments)

I doubt if there's anything Pre-Built and Open-Source that can do that, but I bet with a few person-years or less of work you could make something with GRASS, PostGIS and/or qGIS that can map the equipment given a GPS & SMS capable tracking device (purpose built or smartphone app). Not so sure about the route finding though.

High Depreciation May Slow Electric Car Acceptance

temojen Six of one, half-dozen of the other (1 comments)

With the electric cars there are no oil changes, (engine) air filter changes, spark plugs, spark plug wires, distributors, tune-ups, injector cleanings, fuel filter changes, etc, plus a whole lot less moving parts, so the maintenence bills (Tires, brakes, windshield wiper blades, washer fluid) should be substantially less.

Lessons In Hardware / OS Troubleshooting

temojen Re:Sooooo (236 comments)

For a failed build, our upstream helpdesks usually recommend HDD, then MB, then PS. CPU and RAM are way down the list (strangely above bringing in a network verifier which almost always finds the problem if the HDD and MB didn't fix it and the deployment is network based). This observation is based on most of the big-time contracting services in Canada.

A Wireless Hotspot For Your Car — Why Not?

temojen Re:Car hotspot? (135 comments)

For most users it may be of limited utility, But I can see it being useful for technicians who may want to be able to connect customers laptops to mobile hotspots to download patches etc, as well as a host of other uses. I've thought of doing this (albeit with a Dlink DiR-655 and rocket stick, not some $300 purpose built device).

Nexentia

temojen temojen writes  |  more than 4 years ago

I gave Nexentia a whirl on a server I'm building at home. It's a Debian/ubuntu based system on top of the OpenSolaris Kernel and core utilities. It looks like it'll be fairly useful. Perplexingly, the default behaviour of shutdown is to put the system into single user mode... which means you have to log in on the console to run poweroff... which means you have to have a console, or learn to use "shutdown -i 5" instead. My plan is to not have a console on this machine as it'll be somewhere other than my office.

My plans for the server are:

  • Play with it a few weeks first so I don't make any rookie mistakes, then Re-install it for
  • A large iSCSI share for my aperture vault and time machine
  • A zone to run a bittorrent client and Samba share
  • A zone to run Cyrus IMAP & MTA and fetchmail as a SOHO mailserver so I can use my email on any of my computers, home or otherwise
  • A zone to run Apache for my own website
  • Multiple zones to run Postgres for various projects and experiments.
  • Multiple zones for various Apache/PHP or Tomcat web projects
  • A zone with a KDE desktop installed to play with XDMCP and to have a KDE system I can access from my Mac Mini.

"clamshell mode" on Kubuntu notebook

temojen temojen writes  |  more than 5 years ago

I was having trouble with my Kubuntu netbook... I use it at work as a portable network tester/console router/manual viewer, etc and frequently have to move from place to place while useing it, but closing it put it to hibernate (slow to suspend and wake up) and changes in "system settings" had no effect.

This line did the magic:

sudo mv /etc/acpi/lid.sh /etc/acpi/lid.sh.notrun

Also, I changed the power button to suspend to RAM.

It's also handy for use at home with an external K/V/M as I can clamshell it and work on the big monitor. With these changes, I'll likely start using it a lot more as I really prefer Konqueror/Kate for web development (due to kioslaves), and it's even quieter than my mac mini.

Income tax preparer's privacy statement

temojen temojen writes  |  more than 6 years ago I went to get my taxes done at a franchise of a big financial services chain. They asked me to sign their privacy policy. When I started to read it the rep said I just had to sign it. I said I was going to read it before signing. She interrupted me several times as I was reading (two pages of small type), saying that I had to sign it before they could do my takes. Meanwhile, she was already entering my information.

I finished reading and said "please stop entering immediately". It seems burried down at the end of the document were two shocking disclosures...

They share all your personal and financial information with other financial services companies for purposes such as ... marketing and debt collection.

To make matters more interesting they send all of your personal and financial information to a foreign country where it may be accessed by any government agency allowed to under the laws of that country..... Under the laws of that country, government agencies may access all information on non-citizens without either a warrant or probable cause. Also, that country has a long documented history of interfering in the internal affairs of other countries.

READ and understand the privacy policy before you hand over your tax return slips

Will the last one out please turn off the distcc cluster.

temojen temojen writes  |  more than 7 years ago Warning!! if you run Gentoo and have not already been bitten by the expat upgrade bug, do not emerge any package that pulls in expat-2.0.1 . It will break your system. Be prepared for a multi-day revdep-rebuild during which time your system is unusable (which may not succeed), or build binary packages (of world) in a jail or on another system.

Version 2.0.1 of the XML Parsing library was recently marked stable on all architectures despite the fact that it causes a segfault in any program that is linked against expat-1 and it does not block on <expat-2.0.0 .

In the forums 1 2 and in the bug reports 1 2 the developers have made it clear that they regard this event as nescesary and desirable (to encourage people to upgrasde to the newer KDE and GNOME versions). Many have also said that this is to be expected in gentoo. Note that expat-2.0.0 did block on <expat-2.0.0, thus preventing it from being pulled in by another ebuild accidentally, and allowing anyone who needs it to go to the forums and see why it was blocked and plan their downtime.

Some users (including me) have responded by switching to other distributions; for us, continuity of service (or at least lack of unplanned downtime) is more important than slighly more flexibility than the norm.

ESMTP Relaying?

temojen temojen writes  |  more than 7 years ago I have a residential ISP (the cable company) and fetch my mail via POP3. I can check my email anywhere, but I can only send email from within their network, in the same city. If I take my laptop out of town or to a hotspot that uses the other major ISP in town (the phone company), I cannot send email.

I am currently in the process of frankensteining an ancient laptop to act as a personal webserver. Does anyone know of a very small linux application that can accept SSL'd and Authenticated ESMTP connections and forward mail on to the ISP's outgoing mailhost? I'm looking for something similar to ssmtp, but able to accept SSL ESMTP AUTH connections. There will be no scripting interpreters on the laptop, so PERL, Python, Ruby, etc are out.

Found on Photo.net: Film vs Digital

temojen temojen writes  |  more than 8 years ago

35mm film/slides consumer garbage??

Perhaps you have it backwards... Consumer 35mm print film is garbage.. shipped and stored in uncontrolled temperatures, for who knows how long, made to wider tolerances, etc.

To make matters worse, auto-everything volume-lab printing is crap. Well, not crap, just set up to make passable snapshots from crap exposures on crap film, not great prints from great images on great film. They're also often set up to save costs by always scanning at 6MPixel, regardless of the intended print size.

Films like Provia, Portra, and even Sensia and Kodak HD (if you get them fresh) are really good. Processing is really good anywhere that the machine is kept clean and running properly and the chemicals are kept fresh.

Scanning the film yourself is the ticket, even with a cheap scanner like the Konica-Minolta Scan Dual IV (which I use). Once you have the exposure calibrated (use the strip at the beginning of the roll that goes from fogged to unexposed), set the whitebalance (just like with digital, have a photo of someone holding a white card in the same light), lock the settings and scan away. You've just made images far better than the minilab would make, assuming your exposures, composition, and subject matter is good.

From that point on, the images are just the same as images from a dSLR, except with more flattering contrast if shooting pictures of people with print film, and higher resolution for a given capital expense. When you interpolate to different sizes for printing, the grain seems to disappear from 400iso. Just like digital, you can print on your own inkjet, send them to a printing service (mpix or whatever) or take them to a minilab to get prints done. If you take them to the minilab though... tell them to do no corrections or they'll leave the machine on auto-everything and you'll get crap again (but this applies to any image shot with the camera on any mode but the most basic, film or digital).

Sounds like the rantings of a film zealot? No, if I were running a portrait studio (other than high-end), shooting sports, or photojournalism, I'd probably be using a dSLR for their lower cost per picture and faster results. Most of the techniques I use apply to either film or digital equally well.

From this discussion on Photo.net.

Too Much Scheimpflug

temojen temojen writes  |  more than 7 years ago

I got my 4x5 negs back yesterday... One of them is a really great picture of a tree atop a rocky hill at Pipers Lagoon, but I used too much front tilt to make the rocky hill in focus up it's entire face, and there is severe vignetting (completely black) in the top two corners. Bummer.

On a positive note... I found out I can eliminate newtons rings by scanning the negs emulsion down and mirroring the file in software. The B&W emulsion is too rough to cause newtons rings.

ImageMagick saves the day!

temojen temojen writes  |  more than 8 years ago I've been very slowly working on ~200 images that were very badly damaged at the processing lab last november. There are severe scratches and huge amounts of debris all over every image (possibly exhaused developer at the lab? silver still left in the film? (C-41)). Today I found out that

for i in *.tif; echo $i; convert $i -noise 4 $i-good.tif; done

does the job in about 10 minutes per image for all but the worst damage, which I can clean myself given a clean source to clone from. It does lose a little sharpness, but I have more detail than needed anyways.

Audacity

temojen temojen writes  |  more than 8 years ago I just got the new (as of last November) version of Audacity. It now supports stereo recording with the iMic on MacOS. Given a quiet room (blanket over window, only laptop on) and the built in noise reduction filter it's quite easy to create a high-quality low-noise recording. If I can get two microphones and some way to plug them both into the microphone jack I might just finally get around to doing interviews for CHLY.
