A reader* asks: “Do people drive a lot worse in the rain in Boston, MA?”

Yes, of course. Accident rates in Boston go up in the rain — just as they do in every other location on the planet. I’m not sure what else you’d expect when roads get slippery and visibility goes down! I’m guessing that what you’re really getting at is the poor reputation of Boston drivers; and…

Getting the band back together again…

… or something like that. 🙂 The announcement (in full, below) went out yesterday. TL;DR: Internet maven Woody Leonhard has acquired Windows Secrets, and is merging it with the resources at AskWoody.com, to launch a brand new newsletter, which I’ll be part of. Langa.Com will continue here in its present form and frequency-of-update, but now…

A reader asks: “I dropped my hard drive. How could I possibly fix it?”

That depends on exactly what broke. Pick up the drive and gently shake it. Is there loose stuff inside the housing? If you hear pieces rattling around, you may have broken one or more of the disc platters (disc platters are often made of glass, coated with a metallic layer). And if platters are broken,…

A reader asks: “How can I reduce laptop noise?”

Laptop noise usually comes from four components: the cooling fans; any spinning-media data-storage device (e.g. hard drive or DVD); the keyboard; and the speakers. We’ll discuss those in reverse order, and immediately discount the speakers: I seriously doubt that’s the kind of noise you were referring to! You can just turn down the volume, or…

A reader asks: “How much does charging a mobile phone cost?”

Not much. In fact, probably less than a penny! You can roughly guesstimate it for yourself this way: Note that electricity is usually sold by the kiloWatt hour (kWh) — 1000 Watts delivered for one hour. If you know the Wattage of your phone charger, and how long it runs, you can very easily calculate…

A reader* asks: “Will upgrading my RAM from 3000 MHz to 3200 MHz yield a performance gain?”

Meh. You’ll either see no gain at all; or so little that you won’t notice. Here’s why: The circuits that RAM plugs into are controlled by a clock that sets the pacing for all memory-related operations in that part of the PC. In the vast majority of PCs, the RAM clock speed is set at…

A reader* asks: “Have you heard about the Boston Molassacre?”

I believe that’s a phrase used jokingly by tour guides to refer to the very real “Great Molasses Flood” of 1919. On an unusually warm January day, a poorly-constructed industrial tank containing  2,300,000 US gallons (8,706,447 liters) of hot, fermenting molasses burst, sending a wave of heavy liquid, initially 25ft (8m) high, at 35mph (56km/h)…

A reader asks: How can I check which .Net version is installed?

Q*: How can I check which .Net version is installed on a Windows 7 PC without administrative rights? A: There are many ways to check, regardless of Windows version or Admin status. Most only take a few seconds. For example, try this: Open Windows’ built-in Registry editor (RegEdit), and click to: \HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full With…

A reader asks: My PC has an SSD; will adding an old, slow HDD make my whole PC slow?

Nope — not if you’re smart about how you set it up! Older, slower drives are great for medium-to-long-term data storage — files that you want to have handy and accessible, but that are not in constant use. Think of things like music, photo, or video collections; backup copies; system images; ISOs; and so on….
