You want a GPS

This is more of a confession than a review, but it may help out someone else as confused and unaware as I was. I should have bought a GPS some time ago, and only did so because we are planning a cross country trip. I had no idea how useful this would be for local travel and really wish someone had told me to buy one..

Adding Memory

Used Servers - Black, White or Gray Market?  
- Buying used server equpiment: In the field, the word "gray market" is typically thrown around with disregard for it's real meaning (product acquired from an overseas channel at lower prices than said product is provided in the local channel) in order to spread FUD. Some reps will even go as far as to refer to used IT hardware as "black market" or stolen/counterfeit equipment. -

First you open it..   2011/11/28 anonymous
- How to open a Dell SX270. This morning I wanted to pull the hard drive from an old Dell Optiplex SX270 I have hanging about here. I looked the darn thing and saw that someone else had been this way before: all the screws had been removed from the case.. but as it turned out, that was a complete red herring. You don't need to touch a screwdriver to open this puppy. Well, maybe one, but I never saw it in, so I'm not sure. You do have to be brighter than I am, but just in case you are equally challenged, here's how you open a Dell Optiplex SX270. -

Granite Digital USB to SATA/IDE Adapter  
- Handy tool for techs mounts hard drives by usb: While this is definitely NOT the way you want to run an external drive for any length of time, it is sometimes very handy to have quick access to a bare drive that you just tore out of something and that isn't going to have a permanent home again. This can be for recovery, file transfer, or just sanity checking: if you are a tech, you want to be able to do this: -

No more Parallel/Serial?  
- Is parallel port printing gone? If not, it certainly will be soon as USB replaces all of it. A PCI card can be a replacement, but not always. -

Insert System Disk  
- All righty, there is an intermittent problem here. Maybe the hard drive, but I looked in the syslog and there was nothing there. So, I put the machine under heavy load: reading and writing the tape drive, continuous "ls -lR /" loops running, copying big files to /tmp in other loops, all with random sleeps. Sure enough, twenty minutes in the disk stopped responding. Nothing in the logs still, but the machine was locked up. -

Debugging a network failure  
- A heat wave can cause electrical problems: This morning I had a call from a Boston customer. "Everything's down", he said, "Internet and our servers. We can't get to anything. But.. the guys who came in early are still working." -

- I found a professed "competent" student at the local university who spent a couple of hours destroying the setup in one of the machines. We now have one machine working.. -

Badram, Badmem, and Memtest86.bin

scsidev: SCSI utility for linux  
- I recently built an external SCSI enclosure, using an old tower. I used 3 SCSI drives, and built a LVM, so I could concatenate the drives together into one large drive, to host my temporary video scratch files. -

External SATA drives  
- In theory, at least, multiple SATA disks have higher throughput than multiple SCSI drives because they aren't sharing a bus. -

Rebuilding failed Linux software RAID   2011/10/26 kuntergunt
- Rebuild crashed Linux raid. Recently I had a hard drive fail. It was part of a Linux software RAID 1 (mirrored drives), so we lost no data, and just needed to replace hardware. However, the raid does requires rebuilding. A hardware array would usually automatically rebuild upon drive replacement, but this needed some help. -

A Nonvolatile Memory Overview   2012/05/28 TonyLawrence
- This paper presents a basic nonvolatile memory (NVM) overview. Section I begins with the introduction including a brief background of NVM's and the common terms used in the memory industry. The description and explanation of how an NVM is programmed (adding electrons) using hot-carrier injection is covered in section II. Section III covers the erasing or removing of electrons from floating gates of NVM's. A brief mechanism of Fowler-Nordheim tunneling is covered. Section IV introduces the model that can be used to predict the NVM programming characteristics. The hot-carrier injection model addressed is the "Lucky Electron" model. Section V covers the reliability aspects of NVM's. The common reliability issues an NVM encounters are the data retention, endurance, and disturbs. -

Digiboard Serial Ports on Linux Servers

- Embeddable Linux. The intent here is to port Linux to 8086 and 80286 processors. Why not? Xenix ran on those, and while the lack of a protected mode CPU on the 8086, and the limited powers of the 80286 make it all make it all challenging, I had Xenix installations doing real work on 8086 machines. -

- New, very fast RAID controller, burt the customer say it is slower! Why? BDFLUSH and NAUTOUP are the culprints. -

Parallel printer cable length  
- The docs for OS/2 stated that 6 feet was the maximum length the printer cable could be for a parallel port connection. So, I guess the OS has something to do with this spec? Limits to Parallel printer cable length. Given that reliable parallel port operation limits one to a cable length of no more than 15 feet, network print servers make a lot more sense. -

Why I have to use Unix: scanning name tag badges  
- Use Unix to scan name tag badges with a quick and dirty Perl script. You could add more features, like storing the full date and time instead of just a "1" and so on. -

Comments on Uninterruptible Power Supplies  
- My recommendations are based on a lot of real-world experience with manufacturing environments, which tend to pose the greatest difficulties in providing computer-grade electrical power. -

Protecting from Lightning  
- Grounding is everything, especially if building B gets its power from building A. A high quality UPS is essential to protect hardware from power line hits. -

How do you protect yourself against lightning?  
- Although our hit was not that bad, mostly NICS, and some serial interface cards for our dot matrix printers. -

- Personal Digital Assistant. In other words, something very computerlike that can range from just a simple notebook/calendar to pretty near a full-fledged computer. I don't use one myself, for what's probably an odd reason: I find I do better remembering stuff if I don't write it down. -
