Back in April I decided to put down a deposit on a Tesla Model 3. When my number came up, though, the price for even a minimally-configured unit was far more than I was willing to pay, so I put off the purchase.
A recent article in TidBITS announced that the $20 WyzeCam Security Camera Is Almost Too Good to Be True. Joshua has been having a lot of fun with security cameras lately. He converted some old phones into surveillance equipment using Haven and Alfred. But $20 for a full-function dedicated camera just seemed like a deal we couldn’t pass up.
Sometimes, it’s simple things. We’re surrounded by wonders like smart phones and miracle drugs, but sometimes innovation can come entirely from just thinking about a problem differently. If you took an iPhone X 30 years into the past, it wouldn’t do much. Oh, it might be a shiny curiosity, but its function would be limited. Nor would someone in 1988 be able to disassemble it, discover its “secret” and make more of them: the main secret is layer upon layer upon layer of incremental improvements in processor design, chip fabrication, wireless technologies, display mechansims, battery capacities, operating system architecuture… the list goes on and on.
In spite of having cleaned up my container lid drawer, I still have problems with drawer clutter. One place I particularly notice is when looking for measuring cups. I like to bake, and so individual-size cups are essential, but I hate pawing through the drawer looking for the right one.
Most email users are blissfully unaware of the magnitude of the spam problem. Major email providers do a pretty good job of filtering, so you might see little or no spam in your inbox. Even the stuff that gets sent to your “spam folder” is only a tiny fraction of the spam that gets sent to you. That hides the magnitude of a really big problem, and one you pay for even if you don’t realize it.
If you don’t know what IPv4 and IPv6 are, this post isn’t for you.
If you know, and are wondering how you might implement IPv6, this might be of interest. We handle http/https requests using a white box router running Debian. Until recently, we were IPv4 only, and the router used NAT to connect to an existing subnet with a local IPv4 address space (in the 10.x.x.x range). What makes it odd is that the subnet is also reachable through a different IPv4 address and NAT—it’s ancient history in a network that has been running since the 1990’s.
My old bed cost, I think, about $1,500 and was too big — Caper and I rattled around in it. It was also over 10 years old. I got a Wirecutter recommendation for a compressed foam mattress that you can order online and it comes in a relatively tiny box — for less than $300. Uncrate it, and over a day or two it expands to a full 12″ deep mattress. I bought one for Matthew, and he liked it, so I decided to upgrade (and downsize) my own bed. Continue reading
I have a number of industrial racks I use for servers and storage. They’re a fairly standard design: angle iron and particle board. Interestingly, some came with no feet (which would be fine on concrete, but I have actual tile floors). Some came with only four feet. Some came with eight feet, the other four serving as caps on top of the angle-iron uprights.
When I first got a 3-D printer, I was excited to discover that somebody had already uploaded a design for feet to Thingiverse. The design was for much larger shelves, but it worked—it was, perhaps, the first actually functional print I made.
