When will people learn to properly escape preformatted blocks?

I've noticed this when I first posted source code in Haskell to this blog few months ago. I think I have encountered this problem before (maybe even multiple times!), but it was so long ago that it slipped my mind. So it happened that I have posted unescaped code between <pre> and </pre> tags. This is trivially a silly act (imagine if your source code had </pre>...) and the standards are also clear on this issue: HTML 4.01 Specification: Character entity references [w3.org], Using character entities and NCRs: When to use escapes [w3.org]. Always remember to escape at least &lt;, &gt; and &amp;!

You may be wondering how I noticed that in the first place while most web browsers today are so forgiving. Some years ago when I first committed this error (perhaps with comparison operators), I have fixed it myself because on second thought it was trivially ill formed (and I have also looked it up in the standard later). But this time, it was by accident! :) I have mentioned this before, but I repeat that I'm regularly monitoring my web creations using many different browsers. They give different results because some have very strong standard adherence, while others simply have differing error correction heuristics.

In short: links2 eats the remaining line following a monadic left pointing binding arrow! :-D

Tftp secret of TL-WR740N uncovered

I've found out that even this particular entry level router supports anti-bricking, so there's no need for soldering, unless of course you are modding. The method I used is the following: Set up a tftp server  on your PC and verify if it works correctly (configuration, permissions, firewalls, etc.) Rename your target firmware to wr740v4_tp_recovery.bin and copy it to your base folder (by default /tftpboot). I tested with openwrt-ar71xx-generic-tl-wr740n-v4-squashfs-factory.bin r43602. Set up the following static IP for your PC: 192.168.0.66 /255.255.255.0. If you're not sure about the firmware name on a different model, start a packet sniffer on your PC ( tcpdump -i eth0 -n -l ) and look for the name in the RRQ message. Preferably disconnect WAN from the router Connect the PC to a LAN port Power off the router Press and hold the reset button Power on the router After the leftmost (power) LED and the rightmost (padlock) LED turn on alone in a few seconds, release

Hidden TFTP of TP-Link routers

I did some more investigation after the positive results with the TL-WR740Nv4  (click the link to get introduced to the way of recovery). Most users report that devices and firmware updates released after a point in time usually have this mode enabled. If a firmware update is available from the vendor for your device, it's a good idea to apply that update before installing OpenWRT or dd-wrt UNLESS you own something for which upgrading will ensure incompatible with OpenWrt, like a TL-WR730N , and possible some other models (please report). Note that some old models have newer updates in different languages, those may also be worth a try ( TODO : compatibility?). Also remember that later on, tftp recovery will need a type of firmware image without a boot loader, so strip it with dd if yours has it ( grep U-Boot , or check the filename). Positive reported claims so far (personal results highlighted): TL-WDR4300 router 192.168.0.86 server 192.168.0.66 query wdr4300v1_tp_recovery.b
