Replacing a Memopad HD7 screen

It probably was just a matter of time, but one of my sons dropped his Asus Memopad HD 7 and cracked the digitizer assembly. What we usually call the screen actually sits behind the breakable piece of glass, and more often than not, it’s the glass digitizer that breaks. I left it that way for a while, but once the screen cracks, the cracks tend to spread, and eventually the tablet will get to a point where it’s unresponsive.

Replacement digitizers are available on Ebay. Note the exact model number of your tablet (my kids have ME173Xs, so here’s an ME173X screen) because they aren’t all interchangeable. The part costs around $20. It took me about three hours to replace because it was my first one. If I did this every day I could probably do it in 30 minutes, and I’m guessing if I have to do another–ideally I won’t–it will take an hour or so.

Will ARM overtake x86?

Will ARM overtake x86?

Here’s an interesting question I got recently: Will ARM overtake x86?

I think the answer depends on how you define “overtake.”

Upgrading a Compaq Evo D510 for Windows 10 and beyond

I had an old Compaq Evo D510 full-size tower/desktop convertible PC, from the Pentium 4/Windows XP era, that I wanted to upgrade. The machine long ago outlived its usefulness–its Pentium 4 CPU is less powerful than the average smartphone CPU while consuming enough power to be a space heater–but the case is rugged, professional looking, and long since paid for. So I thought it was worth dropping something more modern into it.

I chose the Asrock Q1800, which sports a quad-core Celeron that uses less than 10 watts of power and runs so cool it doesn’t need a fan. It’s on par with an early Intel Core 2 Duo when it comes to speed, which won’t turn any heads but is plenty fast to be useful, and the board can take up to 16 GB of DDR3 RAM and it’s cheap. I put 16 GB in this one of course. I loves me some memory, and DDR3 is cheap right now.

Intel and Micron imagine a future beyond flash memory

In the shadow of Windows 10, Intel and Micron announced a new type of persistent memory that’s 1,000 times faster than the flash memory in today’s SSDs. It’s still not as fast as DRAM, but it’s fast enough that it’s going to make things possible that weren’t before.

Intel and Micron weren’t the first to develop something like this–HP has been working on something similar for years–but HP hoped the product would be out by now, and as far as I know, it didn’t happen. It looks like Intel and Micron’s similar technology is going to happen.

Women in tech: The forgotten story of Vector Graphic

Women in tech: The forgotten story of Vector Graphic

I frequently hear lamentations about the number of women in the technology field–or the lack of them. Although there have been a number of successful women in the field, such as Meg Whitman, CEO of HP and formerly Ebay; Marissa Meyer, CEO of Yahoo; and Carly Fiorina, former CEO of HP, men outnumber women in the field and often by a large margin.

That perhaps makes it even more sad that few remember Vector Graphic today. In July 2015 Fast Company profiled this pioneering computer company that time forgot.

Need a good, cheap dual gigabit NIC? I have just the thing.

If you need gigabit ports for your home server or router project and you’re short on available expansion slots, I have just the thing. Home sysadmins have known for a while that you can get cheap PCI-X Intel NICs and run them in PCI mode, but you may not know that you can find the very same thing by searching Ebay for HP 7170 and it’s usually cheaper. It’s not rare to find them for $7, shipped.

What to look for in a performance SSD

The Register has a nice writeup on performance SSDs. The only problem is that performance is really a matter of diminishing returns, and The Reg didn’t report on random I/O.

Tips for buying computer memory

Tips for buying computer memory

Many years ago, I wrote something titled Memory Buying Secrets. That post is lost to history, thanks to migrations in this site’s early years, but there are a number of things you need to know when you’re buying memory that can save you money and frustration, so I figured I would revisit that topic today. Here are my tips for buying computer memory, based on decades of experience. Read more

Hot tip: Memory probably isn’t going to get much cheaper

Hot tip: Memory probably isn’t going to get much cheaper

Friday I saw a story from a financial publication suggesting that DDR3 DRAM prices will be increasing soon due to increasing demand for PCs, thanks to Windows 10’s release and the back-to-school season.

That got me thinking, and while memory prices aren’t at an all-time low right now, they are pretty cheap. A Crucial Ballistix Sport 16GB kit runs about $105 right now. About two years ago, I paid $99 for the same kit. According to the pricing history available to me, the cheapest it’s ever been was $70, and the highest it’s been is $160.

SSDs, factory resets, and why you probably need encryption

After the story came out about factory resets not adequately clearing flash memory in phones and tablets, one of my college buddies asked me if a similar problem exists in SSDs.

Depending on the SSD, it definitely can.
