Keyboard UX Fixed, by Logitech… but it never caught on.

I’m selling a keyboard, the Y-SU61, that, in this specific version, has a keyboard UX issue fixed. Most of the other Y-SU61s don’t have this issue fixed… so these product names are not necessarily meaningful.

This keyboard is for beginners new to PCs. By removing the “insert” key from above the “delete” key, they avoided the problem of pressing the “insert” key and going into “insert mode”, and then typing, overwriting the text that was already there. Beginners don’t know what “insert mode” is, and and get confused when their typing wipes out the existing text. Typically, there’s no indication you’re in “insert mode”.

You can still go into insert mode by pressing “insert” on the keypad.

Having “insert” above “delete” implies that they will work similarly: pressing “insert” should insert a space to the right, just like how “delete” removes a character from the right. This function’s completely useless, but the positioning implies something like that. Alternatively, it could be labeled “backspace” and behave like the backspace key.

Look at the other keys. “Home” above “end”, and “page up” above “page down”. They act the same. The key above “delete” should do something related to “delete”.

Also, pretty obviously: “home” and “end” could be relabeled “top” and “bottom”.

We don’t notice these problems because we’re used to this screwed up keyboard.

However, if tablets really take over, we’ll be facing this problem again.  Tablet users typically don’t have insert mode.

WordPress Concepts and Parts for Beginners

(I’m helping a person on simbi.com learn about WordPress plugin development. Sometimes, an article will be produced to elaborate on a topic. This article explains WordPress concepts and components.)

WordPress isn’t just blogging or CMS software, it’s a framework for general website development. Like every framework, it comes with a huge library of objects that you’re supposed to use to create your applications. This article will describe many of these objects.

TP-Link TL-WA801ND: Nice

I just installed one of these at home, and it’s great. It reminds me of OpenWRT, the open source router firmware, in that it allows you to turn the router into a WiFi client, a wireless bridge, an access point, or a range extender. It’s super-cheap at around $25, and extremely easy to configure with the provided configuration wizard.

Anyone who knows what the different modes are, and how to configure an access point, can set it up in ten minutes.

It even does VLANs! Well, not really – it allows up to four SSIDs and will send each one to a different VLAN. That’s the bare minimum needed to set up access points with guest and private networks. So you can combine that with a lower-end smart switch, and do a little enterprise-style WiFi on a small budget.

It even supports “Passive POE”, which is just a power injector device. The device doesn’t support any of the standard power-over-ethernet standards.

When Does the PageRank Patent Expire? January 9, 2018

January 9, 1998: Google’s filed for its PageRank patent on that day. Patents expire 20 years after the filing date, or January 9, 2018 for this patent.

Shortly thereafter, all the search engines will probably deploy some kind of PageRank algorithm. This will start the slow erosion of Google as the top dog of search engines. PageRank isn’t the only determinant of search result quality, but PageRank made Google.
