I was trying to install some software last week and I got an NSIS error like the one to the right. The message certainly suggests corrupt downloads, but corrupt downloads are relatively rare, and when they happen, redownloading it ought to clear that up. Getting two of these failures in a row with different programs is really a freak occurrence, so I started looking for another problem.
CP/M was, as you probably know, the first popular microcomputer operating system. It was good but imperfect, and its cryptic command for copying files, PIP, is often cited as an example.
Copy makes sense. Even the Unix equivalent, cp, makes sense–it’s copy without the vowels. But what does PIP mean? What’s the origin of CP/M’s PIP command?
Someone I know got a tech support scam popup that said their computer was being hacked. I said to bring the computer over. I wanted to see it.
I found the malicious site in the browser history–I’ll tell you how to do that after I finish my story–and pulled the page back up. The computer played an MP3 file with a scary-sounding message and urged me to call an 888 number. So I called. I got voicemail. I left a message.
Last week, Microsoft quietly released its convenience update pack for Windows 7, 8.1., and Server 2008R2. This is a great opportunity to catch up on Microsoft patching, as it incorporates all of Microsoft’s OS-level updates from the release of Service Pack 1 to April 2016.
Here’s how to use this to clear your corporation’s backlog of Microsoft patches. No, I haven’t seen your corporate network, but I’ll bet you have one.
Disassembling a Lionel 1001, 1060, 8902 or 8302 locomotive isn’t too difficult. The biggest problem is knowing where the three screws are that you have to remove.
These particular locomotives weren’t really designed to be repaired, but there’s some basic work you can do on them with household tools. The 8902 and 8302 locomotives can be cheap sources of a motor for other projects.
One of the new features of Windows 10 is better file compression, which was intended to help Windows fit better in low-resource devices like tablets. But it’s helpful on computers with SSDs too. But for whatever reason that option doesn’t show up on mine.
But you can still compress your system files even if the Disk Cleanup utility (which you can also launch from the Free up disk space by deleting unnecessary files control panel) doesn’t show the Compress system files option.
A lot of people seem to be looking for help cleaning up hacked or infected web sites lately, so here’s a trick I used in the past to locate and clean up infected PHP files.
I picked up a couple of refurbished Linksys EA6200 routers this past weekend. For whatever reason, DD-WRT isn’t officially supported on them, though it does seem to be a popular DD-WRT router. A lot of people make the upgrade far more difficult than they need to. With some simple hacks, Linksys EA6200 DD-WRT installation is pretty straightforward.
I came up with an 18-step process that I simplified just as much as I could. Unlike some methods I’ve seen, I don’t have you editing any binary files or creating custom startup scripts.
I had a Java app pointing at a Websense (now known as Forcepoint) proxy server. The proxy server wasn’t working, and the app was giving me a 407 error.
We had Websense set to require NTLM authorization, but it turns out Java won’t do NTLM, so the Java traffic wasn’t even showing up in the monitor.
My workaround was to have users open a browser, then go to any web page immediately before opening the app. By letting the browser authenticate for it, the Java app worked thanks to Websense having the credentials cached.
If you want, you can launch the applet with a batch file that uses IEcapt to hit any web page, then starts the applet.
