I was shopping for a new vacuum cleaner when a saw a portable carpet cleaner. Basically a vacuum with a precision nozel bolted to a water sprayer. It has been a complete game danger for cleaning up the mess my cats would sometimes leave. Although it is still not as effective as the course of dewormer their vet prescribed.

Just public key cryptography. All your actual posts and comment history are already shared. What is missing is a way to authenticate yourself to anyone but your home server. If the protocol included every profile having a public key, you could then use that to authenticate to any server. And managing that private key is no more complicated than managing your private key in a block chain context.

Non public info like subscriptions is a bit more complicated, because there is an actual policy question of who you share it with. You would either need to make it publicly available, keep a copy yourself, or have your home instance give it to you/the other server at the time you want to migrate.

The actual difference between a working new mouse and a failing double click mouse is in the button itself (mechanical parts are almost always the problem).

However, it is not some exotic failure mode. All mechanical switches have a “bounce”, where the contact makes and breaks a few times before settling into the connected position. Switches are typically designed to make the actual contact spring loaded (which is the origin of the click sound you here). As they age, this mechanism degrades, making the bouncing problem worse.

However, this is a well understood problem that any electrical engineer should be familiar with. One solution is to install a filter capacitor. Now it takes longer to switch between the on and off state, so the inherent bounce in the switch is smoothed out to the point where you cannot detect it.

They probably did testing with a new switch, and decided that they didn’t need to include any explicit debounce component, ignoring the fact that the switch would degrade over its lifetime.

The annoying thing is that fixing the double click is stupidly easy. Years ago, I got frustrated with that exact problem (after a string of 3 mice that each lasted only a few months); so I opened one up and soldered on a random capacitor I had lieing around.

Capacitors like that cost literally less than a penny, and are no more complicated to install at production time than any other component already on the circuit board.

In addition to the raw compute power, the HP laptop comes with a:

• monitor
• keyboard/trackpad
• charger
• windows 11
• active cooling system
• enclosure

I’ve been looking for a lapdock [0], and the absolute low-end of the market goes for over $200, which is already more expensive than the hp laptop despite spending no money on any actual compute components.

Granted, this is because lapdocks are a fairly niche product that are almost always either a luxury purchase (individual users) or a rounding error (datacenter users)

[0] Keyboard/monitor combo in a laptop form factor, but without a built in computer. It is intended to be used as an interface to an external computer (typically a smartphone or rackmounted server).

Miniaturization is amazing. The limiting factor to how powerful we can make phones is not space to put in computational units (processors,ram,etc). It is the ability to deal with the heat they generate (and the related issue of rationing a limited amount of battery power)

At a $188 price point. An additional 4GB of memory would probably add ~$10 to the cost, which is over a 5% increase. However, that is not the only component they cheaped out on. The linked unit also only has 64GB of storage, which they should probably increase to have a usable system …

And soon you find that you just reinvented a mid-market device instead of the low-market device you were trying to sell.

4GB of ram is still plenty to have a functioning computer. It will not be as capable of a more powerful computer, but that comes with the territory of buying the low cost version of a product.

No. It is the equivalent of a PC maker going “yeah. I don’t think we are going to put in a CD drive anymore because the DVD drive we have been including for years can do CDs as well”

Does you website you linked have any relationship with the research being discussed in the article?

Agree on going with safty razors, but once you are there, you don’t want to cheep out. The one option my local grocery store carries is a $20 that is complete junk. I invested $70 in a Henson safty razor and never looked back. They also have a $250 offering for people who want the benefits of a safty razor without the cost savings.

For blades, I actually splurge and buy the $0.20/piece offering from Feather instead of the $0.10/piece ones that Henson sells. Still cheeper than the $0.80 safty blades the grocery store sells, or the checks app $4.50/piece cartridge blades the store sells?!?

Moral of the story: go cheap, but don’t be afraid of spending a little money to do so.

Translating into Linux terms, Steam has dropped support for:

• Ubuntu 8.04 LTS Hardy Heron
• Ubuntu 12.04 LTS Precise Pangolian
