pull down menu over graphic
by Jack 09 May '05

09 May '05

Help! I know I must be doing something wrong. Can anyone show me a sample of how to create a pull down menu over a graphic image in a table data column. I prefer a javascript or php solution, but I'll take perl or whatever. I thought I had it, but it's not working. It needs to disappear when not activated and appear when a mouseover or click event happens. I've wracked my brain on this and tried many 'menu code samples' to no avail. Brian D. Discover Yahoo!

Netgear - two strikes
by Jonathan Hutchins 06 May '05

06 May '05

So the pub over hear has one of those nifty Netgear MP101 players, connects wirelessly to your PC and plays all your MP3's into your stereo. Handy little simple remote to control it. Problem is, the "server" runs on an XP box with a USB DSL Modem on it. XP thinks this is the primary network device. There's supposed to be a configuration button that lets you tell the Netgear software to listen on a different subnet, but the button doesn't show up (because it's a USB device? I dunno). (The secondary connection is a standard NIC connected to a Cisco WAP.) So I had a Wireless router en-route from the states. Unfortunately, the 7-10 days shipping ended up being 16 days, and I only have a couple of days left. I open the box, and I see "Netgear". Uh-oh. Sure enough, I set this up on the home network, and as soon as I access the configuration pages on the router, it goes offline. Won't respond to "ping" any more. I can unplug it, it will start up and supply an IP address via DHCP, but as soon as I hit the web pages, poof! Wireless connectivity on it defaults to "off", so I'm pretty well sunk here. Oh, it won't pass packets through on the home network either. It would be double-NAT by default, which is probably why. NETGEAR refused to reply to support email unless I registered the music player. I couldn't guess a purchase date their registration site would accept, so that's sunk. I registered the router, but what are the chances that they're going to get right back to me on a Friday afternoon, and that I'll get it worked out by Monday when the movers come. Ah well. Soon I'll be back in the U.S. and I can take this router back and tell 'em where to stick it. The pub's on their own.

Dates again
by Jonathan Hutchins 05 May '05

05 May '05

Just a follow-up on our earlier discussion of why it's important to have your date set correctly: I'm using Squirrelmail pretty much exclusively right now, being in England. SM 1.4.4 doesn't have the ability to sort by order received, nor to find "next unread message". It's not a problem in this list, but in my main inbox I've accumulated six "new" messages buried somewhere in the "past" because their date is incorrect. Most likely just spam, and I'll track them down when I get home, but there it is. I just deleted the offending messages in here that were "stuck" at the top of the list because of their back-to-the-future dates.

Here's the short summary of what's going on for those who didn't bother to follow the link... You ping 127.0.0.1. ping uses inet_aton from the standard c library to convert the string 0x7f.1 into a 32 bit integer value. The string is assumed to be a series of numbers separated by .'s. A number prefixed with 0x is assumed to be hexidecimal. Likewise, were it to be prefixed with only a 0 it would be assumed to be octal. This is standard practice for ascii to number conversions. Each number is assumed to be an 8 bit value. However, the rightmost number in the series is as big as the remaining number of bits to be populated in the 32 bit value. So... 127.1 = 01111111 000000000000000000000001 127.0.1 = 01111111 00000000 0000000000000001 127.0.0.1 = 01111111 00000000 00000000 00000000 I wonder how it works out under IPv6? Garrett

Or extract to dir., compare to final destination dir. And then mv file. You may want to compare filenames and dates to keep the newest or oldest file based on preference.

Same thing that happens if you ping 127.1 or 127.0.0.1 or 12.1 or 0xc.1 or 0x7c.0xf1 or ... ping translates it as x.0.0.y and runs the query. I would say that this is a bug in ping, that it would allow x.y to be evaluated as a complete ip address. But what is going on is that ping is calculating the address based on the first and last dot numbers and fills in the blanks with zeros. if you want the RFC explanation for it, I'd have to look it up. I don'ty keep that kind of trivia in my head, hell I have a hard enough time keeping in the important stuff. ;') Brian D. __________________________________________________ Do You Yahoo!?

Does not make it not a bug. I still consider it a bug. Here's my reasoning, if a program does an interpretation of the user input that the user might not have intended then ... it might be a bug. If a program behaves in an irrational way to input then ... it might be a bug. If a program fills in missing information then ... it might be a bug. It's certainly a nice little l33t trick for those in the know to use for short-cutting, etc. But, it's still is translating what might have been an accidental <CR>. I might want to ping 12.1.0.5, but if my hand slips and I hit return after 12.1 or 12.1.0 then I wind up pinging the wrong address (12.0.0.1 or 12.1.0.0). But even bugs have uses, whether they are intentional or not. ;') Thanks for the trivia, Gerald. Brian D. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

RE: database
by Leo Mauler 04 May '05

04 May '05

Another question regarding databases. I'd prefer using ANSI SQL or even SQLite, but the issue has come up that the local newspaper managers might want the database output into Microsoft Access. Is that easier to convert from Access to SQL or easier from SQL to Access? (I think I know the answer, I just want to hear it from someone who does this professionally) Also, is it easier (or better for that matter) to use an SQL database when putting it on the Internet? In other words, if I'm forced into Access should I create a side copy in SQL just for the Web? --- Leo Mauler <webgiant(a)yahoo.com> wrote: > Here's an interesting question: if one uses SQLite > and suddenly needs MySQL or something else more > complex than SQLite, how complex will the > conversion be? > > --- "Timothy A.

Yes, it was a script first and book later, as far as I know. The first 2 episodes didn't have to be boring, he let them be. What is next in the Dune series after Children of Dune?
