An insider’s account of the fall of Radio Shack

When I heard Radio Shack was going to be open on Thanksgiving day, I wondered why they would bother. The few Radio Shack stores near me are deserted on normal days, so I didn’t know why anyone would take time out of Thanksgiving Day to go to Radio Shack.

Based on this sad account from an employee who spent hard time working at Radio Shack, I was probably even more right than I thought. The first story, from Black Friday 2004, tells the tale of a store that, when all was said and done, probably lost money on Black Friday. And this was in an era when tech blogs would say, “Believe it or not, there are worse places to be at 6am on Black Friday than Radio Shack.”

I’m not sure anybody believes it now. Read more

What is Winshock?

Dave Farquhar security, Windows , , , , , , , , , , , , , , ,

So the other day I got blindsided with a question at work: What are we doing about Winshock. Winshock, I asked? I had to go look it up, and I found that’s what they dubbed what I’ve been calling MS14-066, the vulnerability in Schannel, which is Microsoft’s implementation of SSL/TLS for Windows.

Based on that, I’d argue it has more in common with Heartbleed than Shellshock, but I guess “Winshock” is catchier than “Winbleed.”

Then the lead of another team asked me to brief his team on Winshock. I actually managed to anticipate all but three of the questions they asked, too, which was better than I expected. Some of what I shared with them is probably worth sharing further.

Why accordion-style flexible drain pipe is against code

Dave Farquhar DIY, Landlording , ,

From time to time I see accordion-style flexible drain pipe (also sometimes called flexible waste pipe) in use, much like the one below. St. Louis County inspectors take an exceptionally dim view of these, and I always wondered what the big deal was, since literally every hardware and home-improvement store in St. Louis County sells them. Why would they sell something if it isn’t okay to use it? Read more

What to look for in a 2014 bargain Android tablet

Dave Farquhar Android , , , ,

I guess I owe an apology for not writing and posting this last week, when $40 tablets were all the rage as doorbusters. Cheap Android tablets are back again, and people are going to buy them–so it pays to buy one worth having, rather than one that’s going to drive you nuts.

Here’s what I look for, and you should too: Read more

4K displays get affordable for Cyber Monday

Dave Farquhar Hardware , , ,

I’m not quite ready to upgrade to a 4K (4096×2160 resolution) monitor yet, but if you are, Samsung’s 28″ 4K display is on sale for $400 (down from $700) for Cyber Monday.

At that size and resolution, it works out to 165 pixels per inch, which is very close to what we used to call “near letter quality” in the days of dot matrix printers. To me, this seems more practical than using a 42″ 4K television, and the refresh rate is much better.

Keep in mind you do need Displayport to drive a 4K display. Most video cards costing $100 and up have those these days, but even some Geforce 210 cards have them, like this Jaton.

Tips for using Dept. 56 and Lemax-type buildings with Lionel trains

Tips for using Dept. 56 and Lemax-type buildings with Lionel trains

A frequent question I see regards the proper scale of snow village-type buildings, like Department 56 and Lemax, and whether they’re suitable for use with Lionel electric trains.

The answer is that their scale varies, but the buildings work very effectively with traditional Lionel trains, or, for that matter, 1:64 S scale American Flyer trains. Many hobbyists have built elaborate winter-themed layouts using these buildings. Typically the scale runs from anywhere from 1:64 to 1:48, with lots of selective compression to make the buildings fit an approximate footprint. The very same thing is true of the Lionel trains of the 1950s, so, intentional or not, they end up being a pretty good match.

The figures sold with these buildings, on the other hand, tend to be much larger–very close to 1:24 scale. This discrepancy bothers some people more than others. 1:24 figures are better suited for G scale.

Fixing the .NET Framework

Fixing the .NET Framework

The bane of my existence as a sysadmin was .NET. It would corrupt itself randomly, sometimes taking with it this awful now-defunct product written in .NET that nobody else wanted anything to do with. Those were the bad old days. These days, there’s a better way to go about fixing the .NET Framework when it goes bad.

Veracrypt is a Truecrypt alternative if you’re looking for one

Dave Farquhar security

I’ve written about Truecrypt before. If you need cross-platform full-disk crypto, here’s an alternative I found recently. Veracrypt is based on Truecrypt, but since you can’t fork it without a name change, it has a different name.

I haven’t messed with it yet myself–yet–but if you need this, you probably already know it. And, for the record, I don’t believe there was any conspiracy against Truecrypt.

This should go without saying: Upgrade your WordPress!

Dave Farquhar security

Apparently, 86% of WordPress blogs haven’t been upgraded yet to version 4.0 or 4.01, because they are vulnerable to a terrible cross-site scripting vulnerability.

If you’re reading this, and you have a WordPress blog, go update it. This post will still be here when you’re done. Read more

More encryption = more safety

Dave Farquhar security , , ,

Mozilla, Akamai, Cisco, the EFF, and Identrust are teaming up for Let’s Encrypt, an effort to make SSL encryption free and easy.

This is important, because it means mundane stuff will get encrypted. When SSL/TLS traffic are no longer flagged as special, security will increase. Read more
