I believe Dylan needs the codename associated with max(total_pct). If you add codename to the select in the above query, you will be selecting the codename from the first row of the rows grouped by muid. This will not be the codename associated with max(total_pct) unless total_pct in the first row of the muid group happens to be the max(total_pct). So using Bruce's trick or a sub-select allows the unambiguous selection of the correct codename value. -David ___ vox-tech mailing list vox-tech@lists.lugod.org http://lists.lugod.org/mailman/listinfo/vox-tech

But in the case of ub vs. usb-storage, simply blacklisting or hiding the ub module won't do. You actually have to rebuild your modules after disabling CONFIG_BLK_DEV_UB.

I don't agree. You asked if the PHP APIs allow placeholders and bind values. I don't know and I don't care, but a discussion of their _proper_ use is relevent and worth mentioning. Why? Because someone not familiar with placeholders and bind values might read this and get the idea that the construct you presented is OK, when in fact there is a more robust way.

Also known as placeholders (?) and bind values (the substituted value). But the way you've written it does not account for binding undefined values (which are usually bound as NULL): SELECT * FROM table WHERE stringattribute = NULL This will not select stringattribute's that are NULL. To do that you would say: SELECT * FROM table WHERE stringattribute IS NULL Unless you know for certain that you are never binding undefined values, you can use the following to avoid this problem: SELECT * FROM table WHERE ((?

I'm not sure either ;-> , but I've been hacking together playlists on the computer (via scripts or whatever) and dumping them to the player. Much faster than going through 40GB worth of music on the player's interface. In one sense it does generate playlists on the fly. In DB mode, if you select a group of songs by album/artist/genre, only that group will play. Or maybe I still don't know what on-the-fly means. > * it takes 4 minutes to boot in DB mode (whatever that means...) Yes, startup in DB mode is very slow, but not 4 minutes. Probably better to hack together playlists instead. Oh, another limitation is a 52 character limit on file and directory names. > * sound quality is said to be "OK". Sound quality is excellent. Better than iPod. Better than Creative Nomad. These are direct comparisons with identical files, and are the only other players I've compared. Most of the reviews I read concur with this. I think most of the time people complain about sound quality on MP3 players, it's not so much the player but the fact that they are listening to lossy-compressed audio, and the quality varies depending on the encoder, codec, etc. And this will _never_ come close to being CD quality, despite what people claim. This situation can be helped by using better codecs, like Ogg, and of course higher bitrates. > * maximum volume is not loud enough Not true, unless you already have hearing problems. This also depends to a great extent on the headphones. If you're using massive, over-the-ear headphones with inefficient drivers, or headphones that don't fit snuggly over the ears (allow much of the sound to escape), then yes, it won't seem loud enough, and you'll suck the battery dry faster. I recommend in-the-ear style earbud headphones with a closed design, and a high-efficiency neodymium magnet. I use Sony MDR-EX51LP. > What exactly is SPDIF? Sony-Philips Digitial InterFace. To be specific, the digital I/O on the iRiver H140 is in the form of mini-TosLink (Sony's optical version of SPDIF), as can be found on some portable CD and MD players. Regular TosLink is found on most DVD players and digital audio receivers. mini-TosLink is an 1/8" connecter that can be shared with a line-level analog stereo mini-jack. > And is there any way possible to get one of these things to play in a > car stereo?

Apparently lithium polymer batteries last as much as 3x longer than lithium ion, which is good because like the neuros, the battery in the iRiver is not user replaceable. I'm guessing the iRiver battery is much more expensive to replace as a result. Of course the neuros has the FM broadcasting, which I'm not sure is practical, but it's cool. And it has a large skip protection buffer which is nice. The neuros is also quite a bit cheaper ($300 vs. $400), but there are lower capacity versions of both.

Also what > is the opinion on the flash memory based devices versus the hard drive > based ones? I wanted a Linux-friendly player with a large capacity. After somewhat extensive research, I ended up getting an iRiver H140 hard drive (40GB) player for the following reasons (in order of importance): * USB 2.0/1.1 standard mass storage device (FAT32 file system) * Ogg Vorbis support * No digital rights management and/or copy protection * On-board firmware upgrade * WAV support * Record to WAV or MP3 * SPDIF optical and line I/O ... and not so important, but cool: * Built-in mic for voice recording * FM Tuner * Fully functional remote with backlit LCD You'll definitely want to take advantage of USB 2.0, which means you'll need a USB 2.0 controller and a kernel > 2.4.20 (IIRC). My laptop is USB 1.1, so I purchased an Adaptec USB 2.0 Cardbus adapter (any adapter with the NEC chipset should work), and the transfers are around 10x faster than the onboard USB. The only software you need is the program to create the binary music info database. But there's an open source program that compiles on Linux (iripdb: http://www.marevalo.net/iRipDB/) that will create the database file from ID3 tags and Ogg info (the Windoze program doesn't index Ogg info). This database allows you to search by artist/album/title/genre (play all songs by this artist, in this genre, etc.). I've modified iripdb to fix several problems (broken genre assignment, incompatibility with older versions of id3lib, etc.). I haven't gotten around to submitting the fixes to the author, but I'm happy to share them. Basically, this player works on any modern OS with USB and FAT32 support, so you would never have to touch a Windows machine to deal with this player. So far it's been great and works perfectly with Linux. I believe some of the lower capacity iRiver flash players are also dumb storage devices with Ogg support, in case this one is overkill for you. -David ___ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech

It is possible if APM and/or ACPI is configured in your kernel, and you are running apmd or acpid. I believe ACPI support is more mature in 2.6. Check out the apmd and acpid packages, and related tools and kernel modules.

A UNION is not a join, it's a combination of results from separate queries where the number and type of columns are the same. You actually can prevent eliminating duplicates with UNION ALL, but that's not what you want in this case. > The former concatenates the columns to give two distinct "SSN" columns > and selects all possible pairings of the values in these columns, and > the columns must be referred to with table names to distinguish them.

Well not really because of the use of DISTINCT... Maybe a NATURAL join would work, but the UNION method is the most straightforward. -David ___ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech

To be proper about it, you would normalize this by putting the season and year in respective separate tables, and place foreign keys to these in the SSN table. But it doesn't sound like this schema needs to be overly complex.

By passing the hash as a reference.

Because you've shifted all the arguments into function()'s %hash.

If you still receive legitimate mail from such servers, then no. But I believe most of the major service providers already started doing this some time ago at the ISP level, so you wouldn't receive this mail to begin with. For consumer-grade DSL/cable services, AFAIK it's next to impossible to convince them that any legitimate need to allow such mail would outweigh the potential for spam. > Is anyone here running such a server?

If time is of the essence, you also should consider what database you're coming from and it's level of compatibility with MySQL/PostgreSQL.

In general, I find that the client and admin tools in MySQL are a bit easier to deal with than the equivalent Postgres ones. > where you really get the benefit from MySQL is speed. Yes, it seems the consensus is that MySQL is faster than Postgres, and I've seen it first hand. But I feel the speed issue is often exaggerated and not necessarily true in every situation. It really depends on your schema design, how much data your dealing with, what kind of queries you need to do, etc. I've seen several cases where Postgres performed better than MySQL for certain queries, and vice versa. The point is, make the decision based on the requirements of your applications and how they need to interact with the database. Don't dwell too much on the speed issue. To aid in the decision, you can always design portable applications and test them using both systems. Portability between MySQL and PostgreSQL is not that difficult to accomplish if you're careful. > Unless you need triggers or have an app that specifically and totally > won't run on anything other than postgres, I would steer clear of it. Although it appears MySQL performs better in a majority of cases, it's a bit rash to suggest steering clear of Postgres on the speed issue alone. I suggest trying out both systems, which is the ultimate ACID test (pun intended). -David ___ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech

It was around long before most of the other databases you mentioned, and has undergone many major revisions. If you familiarize yourself with its history, you'll learn that Postgres pioneered many of the advanced features found in commercial databases like Oracle, DB2, etc. Not to mention it's object oriented features...

Then left join score_board onto the previous query: select volunteer_info.* from assignment_data inner join volunteer_info using (user_id) left join score_board using (user_id,event_id) where assignment_data.event_id = $event_id This way you'll still get contact/assignment info where score_board data doesn't exist. -David ___ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech
