One of my most popular videos in 2020 was a simple fix for the Canon scanner. Many users may not have read the manual or noticed that there was a slide switch on the back of the scanner. If they plug everything in, the scanner appears to work. Until they try to scan something. Moving the slide switch from lock to unlock releases the scan head for normal operation. That video has gotten over 5,000 views in the past year. A viewer asked which scanning software I would recommend. I’ve been using VueScan from Hamrick Software for 15 years on my Mac and Windows systems. I only paid $100 USD for a professional license years ago.Read more “Using VueScan As My Scanning Software for 15 Years”
During Black Friday and CyberMonday 2020, I didn’t find any great tech deals at Newegg. Not that they had any of the newest CPUs and GPUs launched in the last three months in stock. But I did find an old school tech deal at Amazon: a 3-for-2 deal on doorstoppers. Back in the late 1990s and early 2000s, many programming books were so thick that they could stop a door.
Here are the three “doorstoppers” I bought from Amazon last month.
- “Python All-in-One For Dummies” by John Shovic.
- “Classic Computer Science Problems in Python” by David Kopec.
- “An Introduction to Functional Programming Through Lambda Calculus” by Greg Michaelson.
Four months before the pandemic shutdown, I started working from home. Which meant I missed the first coronavirus case that came through the office. My work from home desk for the past year was a pair of printer tables in the corner of my dining room. I recently replaced one of the printer stands with a $75 mobile standing desk from Amazon. I’ll talk about the standing desk, the set up for my work laptop, and my first week standing while working.Read more “Working From Home With A $75 Mobile Standing Desk”
This week Apple announced their new MacBook Air, Mac mini and MacBook Pro. Equipped with the new ARM-based Apple Silicon chip to replace the Intel chips. Apple Silicon will let developers create universal apps to run on iPads, iPhones, and Macs. That sounded promising until I heard the name of the new chip—the M1. That’s unfortunate. The M1 by Cyrix was an Intel chip replacement for the Socket 7 motherboard in 1996. The compatibility and performance issues were so bad that it sucked donkey balls. Will the Apple Silicon M1 be the next Cyrix M1?Read more “Will The Apple Silicon M1 Be The Next Cyrix M1”
When I front mounted the Be Quiet Pure Loop All-In-One (AIO) 240mm Liquid Cooler in my Cougar MX330-G ATX case, I couldn’t mount the two Pure Wing 2 120mm fans in the recessed area behind the front mesh panel. Since the screw holes were also recessed in the frame, the long screws weren’t long enough. I ended up mounting the fans to the radiator on one side and used the short screws to mount the radiator to the frame. I’ll show an old school hack and suggest several mounting alternatives for installing the fans in the recessed area to push air through the radiator.Read more “Old School Hack For Front Mounting Be Quiet Pure Loop AIO”
The SilverStone KR01 low-profile air cooler had served me well for the last 18 months. But it didn’t keep my AMD Ryzen 7 2700 processor, overclocked to 3.7GHz, as cool as I would like. My kneecaps got toasty underneath my desk every time I played FortNite or transcoded 4K video. I recently replaced the KR01 with the Be Quiet Pure Loop All-In-One (AIO) 240mm liquid cooler. Idle temps dropped from 45C to 36C and load temps dropped from 85C to 55C. My kneecaps are no longer toasty.Read more “Be Quiet! Pure Loop AIO Liquid Cooler Review”
Last year I looked for an open air ATX bench case to build a modest test system. Popular Tech YouTubers like JayzTwoCents and Paul’s Hardware prefer the Praxis Wetbench open-air bench case. I have two problems with that bench case: too big and too expensive. The Praxis bench case is 18” x 19” x 17” and cost $200 USD. I needed a bench case that was compact and cost a lot less. The Electric Magic Creative Personality open air ATX bench case is 11” x 7” x 16” (standing up) and cost $56 USD. If you think assembling IKEA furniture was bad, try assembling this bench case.Read more “Electric Magic Creative Personality ATX Bench Case Review”
Henry Cavill, who plays Superman in Man of Steel, Batman vs. Superman and Justice League, and The Witcher on Netflix, posted a video on his Instagram account of him building a gaming PC. The video opens with all the parts sitting on a table. Unfortunately, the product names for all the parts were blurred out. Making it difficult to determine which parts were used in this PC build. A PC build video is incomplete without a parts list (see below). In my video, I identified the various parts in a montage.Read more “Superman Builds A Gaming PC”
AMD announced two weeks ago that their forthcoming B550 mainboards will work with the current Ryzen 3000 processors and the future Ryzen 4000 processors, and the Ryzen 4000 processors will work only on the 500-series mainboards.
For users of the Ryzen 3000 processor and/or the X570 mainboard, the future looks bright — if AMD continues the AM4 platform beyond 2020. The existing roadmap started in 2017 and ends this year. AMD haven’t revealed their roadmap for 2021 and beyond.
For users of the Ryzen 1000/2000 processor and/or the 300/400-series mainboard, the future looks dark. Older processor won’t run on the newer mainboards, newer processors won’t run on the older mainboards. Users are crying foul that their recent purchases are now semi-obsolete.
AMD stated that they were breaking platform compatibility because the ROM chip for the BIOS on older mainboards was too small to contain the microcode for multiple generations of processors. Without the microcode in the BIOS, the mainboard won’t recognize the processor to boot the system.
Enthusiasts — a small but very vocal user base — called BS on that specious rationalization. BIOS fragmentation began last year when the Ryzen 3000 BIOS update needed space on the now too small ROM chip. It didn’t help that AMD recommended the 400-series mainboard to users who couldn’t afford the more expensive X570 mainboard, and everyone expected to drop in a Ryzen 4000 processor when they become available later this year.
AMD backed off their initial statement and offered limited BIOS support for the Ryzen 4000 processors on the 400-series mainboard. A default BIOS that supports the existing Ryzen 1000/2000/3000 processors, and an optional “beta” BIOS that supports Ryzen 3000 and beyond (the catch being unable to downgrade the BIOS for an older processor). Not surprisingly, the 300-series mainboard won’t be getting the Ryzen 4000 BIOS update.
For those of us who went through the BIOS woes for the Athlon 200GE and 3000G last year, the Ryzen 4000 processors will probably offer the same pain to an entirely new audience that haven’t dealt with it before.

Every five years I rebuild my FreeNAS file server by replacing old hardware with new hardware. One component that I always toss out after running 24/7 for five years is the case fans. For the 2015 rebuild, I had Deepcool 120mm fans in front, NZXT 120mm fans in back and bottom, and a pair of Apevia 140mm fans at top. There’s nothing special about these fans except for the bottom fan, where air circulation is needed to avoid overheating the hard drives. The regular 120mm fan was 25mm thick and blocked the bottom drive bay. Not a problem when I only had six hard drives. For the 2020 rebuild, I added two new hard drives and needed all eight drive bays. How can I have a fan and a hard drive occupy the same space at the same time?Read more “Installing The SilverStone Slim 120mm Case Fan”
