Mijn zaken vereisen me om de veiligheid van bepaalde dossiers te beschermen. Jarenlang heb ik gebruikt Gecodeerde Magische Omslagen (EMF) van PC-Magisch om die dossiers te coderen, en hen te verbergen van de mening van interloper. Ik hield van het, omdat de dossiers altijd werden gecodeerd op schijf en toch volledig toegankelijk voor toepassingen waren. Nochtans, toen ik aan Uitzicht 64 bevorderde, nieuwe zo volledig verpletterde EMF mijn systeem dat het zelfs op veilige wijze unbootable was. Ik probeerde het tweemaal tweemaal, kreeg met één of andere moeilijkheid terug, en gaf op EMF op.

Ondertussen had ik ongeveer gehoord TrueCrypt, een pakket van de open-bronschijfencryptie voor Vensters en Linux. Het is vrij! Ik moet toegeven dat nadat ik het downloadde, ik wat tijd nodig had om mijn mening rond het te krijgen.

Hier zijn de grondbeginselen:

• Gebruikend de toepassing TrueCrypt cre�ërt u een groot „container“ dossier op uw systeem, groter dan zult u uw gecodeerde dossiers moeten houden. Het kan op om het even welke lees-schrijfschijf, zelfs een geheugenstok zijn, en met willekeurige gegevens aanvankelijk gevuld.
• Het containerdossier kan worden gekopi�ërd, worden bewogen, worden geschrapt of, enkel als een ander dossier worden anders genoemd. Het is niet breekbaar. Het kan om het even welke naam en om het even welke dossieruitbreiding hebben. U kunt meer dan één hebben.
• Met de toepassing TrueCrypt, u zet op dat containerdossier als schijfvolume met zijn eigen aandrijvingsbrief. U kiest de brief.
• De TrueCrypt toepassingslooppas op de achtergrond en leidt TrueCrypt

Volkomen het werken!

Gewoonlijk, heeft een persoon een steun nodig wanneer hun schijfaandrijving ontbreekt. Alle schijfaandrijving ontbreekt ooit - er is geen vlucht van die waarheid. Maar er zijn andere redenen om goede steunen te houden:

• Totale ramp, zoals een brand of een vloed die de gehele computer en alle nabijgelegen steunen vernietigen.
• Weloverwogen ellende, zoals een virus dat belangrijke dossiers schrapt.
• Accidental deletion or modification of one or more files.

I'm sure there are more reasons, but if we cover these we'll probably have the rest covered.

Drive Failure:

Disk drive failure can mostly be avoided by using two mirrored drives in a configuration known as RAID 1. RAID means Redundant Array of Independent Drives, and has several well-defined levels. RAID 1 is a simple comfiguration with two drives which always contain exactly the same information, hence the term "mirrored." If either drive fails, the other simply becomes the system's sole drive and takes over without a hitch. Since the probability of two drives failing at once is very small, RAID 1 pretty well covers that problem. The new computer here employs RAID 1.

Total Disaster:

If the building burns down or floods, the only solution is to have a separate backup stored offsite. This can be on the internet, another building some distance away, or perhaps in a fire- and water-proof safe. At this office a flood is highly unlikely, so we store encrypted DVD backups of...

Few days back, I bought Windows Vista Business Upgrade the other day so I could start playing with it. Since I did not want to mess up the configuration of my current computer, I thought I would install Vista on a blank hard drive.

Sounds easy enough, after all the previous versions of Windows required you to have a legitimate copy of an older Windows operating system and simply asked for that copy during the install so they could verify upgrade compliance.

Before installing Windows Vista, I ran the Windows Vista Upgrade Advisor on my current system. As I suspected, my video card was not up to Vista standards and the 512MB of RAM was on the low end of what Vista wanted. (more…)

And I'm pleased with it.

Performance:

The overall Windows Experience Index is 5.4, which I believe is pretty good. The limiting subscore (5.4) is the disks, actually, and they are very high-speed SATA II 7200-RPM drives, though you can get 10,000 RPM drives which should be faster yet. The highest subscore is the Windows Aero graphics, 5.9. Everything else falls between, so the system is reasonably well balanced.

Quietness:

When there is nothing else going on in the room, TV and the old computer turned off, sitting at my desk, I can hear a faint, low-pitched roar similar to the sound you hear by holding a large seashell up to your ear, but certainly not that loud. It has a resonance to it, despite my efforts to dampen sounds inside the box. I think that the rear fan is the origin of most of the noise. It's not objectionable, because it's faint, but I will probably try to do more to limit the sound, such as:

• Add more sound-deadening material inside the box; there is room on the side cover for more;
• Play with fan speeds. The computer reports its own

You cannot imagine life without Firefox but over time, your favorite browser keeps getting slower and slower.

Not only is it slow, Firefox sometimes hangs for no reason, consumes a large amount of memory and CPU usage can climb to 90% or more when you have multiple tabs open simultaneously.

You have uninstalled most of the extensions and toolbars, deleted all the cookies and internet temporary files, cleared up the file download queue and disabled the background check for software updates but none of this has helped you speed-up Firefox. (more…)

The Intel E6750 Boxed CPU and three Western Digital 320-Gb SATA hard drives arrived today, and now all of the parts are here. I set everything except the case out on the picnic table for a photo. Out of several photos, my sweetie liked this one with fall color in the background :-)

Then I downloaded an Intel video that demonstrates how to install the processor and "thermal solution" (fan + heat sink) on the Intel DP35DP motherboard. After playing the video once, I played it again and did the installation while watching the video. What makes it tricky is that dozens upon dozens of tiny pins on the motherboard socket must match up with a similar number of contact lands on the CPU wafer, without bending any of the pins.

And the CPU is just a wafer at this point, not fragile exactly but the motherboard pins are. You are supposed to set the square wafer straight down on the pins without sliding it at all, but I must admit that when I set it down it wasn't perfectly aligned and it did slide slightly. I hope those pins handled it - I didn't look.

After inserting the wafer you close a little door and then a little spring handle to press the door and wafer down tightly against the...
