The answer is: 17. Or 674. Or 2. Or 4,237. Not all “programs, tasks, and games” are equal. A handful of resource-hungry apps might bring even a top-of-the-line PC to its figurative knees. But you could run hundreds or even thousands of tiny, efficient apps on the same machine. Sorry, there’s no way to answer…

A reader asks: “What do I do with the USB drive that I found in a department-store changing room?”
You have four choices: a safe and ethically positive one; a probably-safe but ethically murky one; a maybe-kinda-sorta-safe one, also with murky ethics; and a totally unsafe one, with murky ethics. The 100% safe choice is not to keep the drive. For one thing, the person who lost the drive might need it or its…
A reader asks: “What happens if Windows is infected with ransomware but the files are already encrypted with TrueCrypt?”
The files will then be doubly-encrypted; once by TrueCrypt, and once by the ransomware. The good news is that the malware can’t read the contents of your TrueCrypt-encrypted files. That’s not what ransomware is really about anyway: It’s not designed to snoop; it’s just designed to take your files hostage. But the bad news is…
A reader asks: “Can you take your electric assisted bicycle with you on a train or a plane in the United States?”
If you can remove the batteries, then an e-bike is just like any other bike, and is subject to the same rules. A battery-less, totally inert e-bike can be shipped by almost any means. Li-ion batteries, if damaged or defective, can cause a very serious, very energetic chemical fire. That’s why shipping Li-ion batteries require…
A reader asks: “Do you remember type-in programs from computer magazines in the 70s and 80s?”
Remember them? I wrote some! 🙂 In fact, I believe I wrote the first type-and-run program to appear in a non-computer, general-circulation magazine, at least in the US. Back at the dawn of the PC era, I was a newly-hatched junior editor at New Shelter magazine; a general-circulation publication with 750,000 subscribers; covering things like…
A reader asks: “Over time, does turning on and off my laptop contribute to wear and tear even with an SSD?”
Yes, with one exception; especially if you mean doing a full shutdown, followed by a full restart some time later. All reasonably current PCs have well-developed power-management systems that are designed to reduce unnecessary energy consumption during use, while the PC is idling, and during restart. Because energy consumption is directly correlated with wear-and-tear of…
A reader asks: “How can you fix an SD card which cannot be formatted?”
Q: “How can you fix an SD card which cannot be formatted? Every time I reformat it the files are still there.” A: The card is probably write-protected by hardware; or by software; or is simply broken. Hardware write-protection: Examine the card for a “lock” or “write protect” slider or switch, often (not always) on…
A reader asks: “How bad is the traffic in Boston, MA?”
As with any city, there are places and times when traffic is bad; and places and times when it’s not. Without more specificity to your question, it’s really not answerable. But here’s how you can find out: Open Google Maps for Boston, and enable the traffic layer; Google Maps will then show you live traffic…
A reader asks: “Have you heard of the TUTAC computer?”
I hadn’t, but I’m glad you asked (thanks!). This was fun to research, not only because it involves an interesting artifact from the early days of computers, but also because it shares a concept with Bandersnatch, the Netflix choose-your-own-ending movie! TUTAC stands for “TUTorial Automatic Computer,” a device that existed only on paper, in the…
A reader asks: “How do I test for hardware driver conflicts?”
In Windows, it’s easy! Open Device Manager by your preferred means (e.g. use search/run/cortana and enter “device manager” or “devmgmt.msc”; or open device manager in Control Panel/Devices and Printers/device manager; etc.). See Fig 1. To make sure you’re seeing everything, click View, and select Show hidden devices. Fig 2. Scroll down the list of devices:…
