TP-Link TL-WR840n vs TL-WR841n

TP-Link TL-WR840n vs TL-WR841n

If you need an inexpensive DD-WRT compatible router, TP-Link is probably your best choice. But there are some big differences when you compare the TL-WR840n vs the TL-WR841n.

I’ve been running the TL-WR841n for more than two years, so I’m familiar with it. I’ve considered supplementing it with a secondary router, and the TL-WR840n was one I looked at.

When will SSDs be cheaper than hard drives?

When will SSDs be cheaper than hard drives?

When will SSDs be cheaper than hard drives? Based on history, it’s possible to make an educated guess, and I’m going to do it.

Back in 2011, I noticed that historical hard drive pricing fell in line pretty nicely with Moore’s Law, and predicted that SSDs would do the same. I predicted that SSDs would reach 25 cents per gigabyte sometime in 2016, and was wrong. They hit that price in 2015. So I was late by a few months.

But I’m still willing to try to predict when SSDs will cost less than hard drives. I’ll predict when they’ll hit parity too. SSDs work differently from hard drives but their pricing trend is frighteningly similar.

Need a Commodore motherboard? Believe it or not you’re in luck

Individual Computers is working on, of all things, a replacement Amiga motherboard that will fit in an Amiga 500 or Amiga 1200 case.

The board will use the AGA chipset that the Amiga 1200 used, but the board will be built using a modern process, modern materials, and as many other modern components as possible.

Intel and Micron imagine a future beyond flash memory

In the shadow of Windows 10, Intel and Micron announced a new type of persistent memory that’s 1,000 times faster than the flash memory in today’s SSDs. It’s still not as fast as DRAM, but it’s fast enough that it’s going to make things possible that weren’t before.

Intel and Micron weren’t the first to develop something like this–HP has been working on something similar for years–but HP hoped the product would be out by now, and as far as I know, it didn’t happen. It looks like Intel and Micron’s similar technology is going to happen.

What to do when your router isn’t in the DD-WRT router database

If you have a router and want to run DD-WRT on it, but can’t find the router in the router database, you may have learned the hard way that the router database is a couple of years out of date.

But not all hope is lost. Here’s how to find a build, if one exists.

Why it’s a good idea to schedule your router to reboot

Many routers, notably Belkins, have a feature in them to schedule an automatic reboot periodically, usually once a week. Frequently this “feature” is there as a workaround, because something about the router’s software gets unreliable if it’s been running longer than a week. So it’s a kludge, but it keeps the thing working without a lot of effort, so the feature is there.

The respectably rock-solid DD-WRT also has the ability to schedule a reboot built in. I don’t know if it’s there to make life easier for developers, or if it’s there to deal with second-rate hardware, or if there was a time when it was necessary and they just never took the feature back out. Regardless, it’s there, though many DD-WRT stalwarts brag about never needing it because their router’s uptime is more than six years.

It’s fun to get into uptime contests, but it’s poor security. If you have a router, it’s a good idea to be rebooting it every so often, so you might as well turn on that feature, even if it costs you some pride. Read more
