RE: TV-OUT on laptop causes major damage, fire / shock

Don't know if this will help, but my brother (a retired EE with AT&T) thinks it's the adaptor. Probably a failed capacitor.

install and use of linux with a drive too big for bios
by hanasaki 06 Jan '05

06 Jan '05

Have an old Asus k7m motherboard who's bios cannot handle the 120gig drive that replaced the 13gig that died. Any tips on how to get Linux installed and running again? thanks

executable help files in Linux
by Brian Densmore 01 Jan '05

01 Jan '05

I was looking at a driver download from Lexar for the JumpDrive secure version 3.1. It has drivers for Linux, Mac and Windows. In the Linux directory is the driver to use the secure functions of the stick/drive. It appears to be gtk based from a hexdump. There is also a .hlp file, which has the magic number and identifier for ELF files. It also appears to be a GTK executable file. I don't recall ever seeing a Linux help file that was actually a program. Is this some new trend in Linux or is it just something Lexar has taken upon themselves to do? I don't have a Linux desktop handy to test this, but will try to load it later and see how well the driver works in Linux and how portable it is. I'm assuming that Lexar has not opensourced the driver, there is no sourcecode included. It's nice to see the support though. When I contacted the support people the second question was which OS I was using. Not which version of Windows. Brian Densmore

Net::RawIP Compile
by Welsh, Ed 31 Dec '04

Hopefully this is an appropriate place to field this. Let me know otherwise. I am attempting to instal the Net::RawIP perl module and keep getting heinous compile errors. I'll take any suggestions as to research resources. This is a fairly clean install of perl and Fedora. I'm thinking that the old code (2000) isn't compatible with the newer gcc. Can someone try this on an older gcc install? thanks Environment: Fedora Core 3 Perl 5.8.5 Libpcap 0.8.3 Gcc 3.4.3 Here are the compile errors: [root@fake Net-RawIP-0.1]# make cp RawIP.pm blib/lib/Net/RawIP.pm AutoSplitting blib/lib/Net/RawIP.pm (blib/lib/auto/Net/RawIP) cp RawIP/libpcap.pod blib/lib/Net/RawIP/libpcap.pod /usr/bin/perl /usr/lib/perl5/5.8.5/ExtUtils/xsubpp -typemap /usr/lib/ +perl5/5.8.5/ExtUtils/typemap -typemap typemap RawIP.xs > RawIP.xsc & +& mv RawIP.xsc RawIP.c gcc -c -D_REENTRANT -D_GNU_SOURCE -DTHREADS_HAVE_PIDS -DDEBUGGING -f +no-strict-aliasing -pipe -I/usr/local/include -D_LARGEFILE_SOURCE -D_ +FILE_OFFSET_BITS=64 -I/usr/include/gdbm -O2 -g -pipe -m32 -march=i386 + -mtune=pentium4 -DVERSION=\"0.1\" -DXS_VERSION=\"0.1\" -fPIC "-I/u +sr/lib/perl5/5.8.5/i386-linux-thread-multi/CORE" -D_LINUX_ -D_ETH_ - +D_IFLIST_ -D_GLIBC_ RawIP.c RawIP.xs: In function `ip_opts_creat': RawIP.xs:444: error: label at end of compound statement RawIP.xs: In function `tcp_opts_creat': RawIP.xs:543: error: label at end of compound statement RawIP.xs: In function `XS_Net__RawIP_tcp_pkt_parse': RawIP.xs:764: warning: use of cast expressions as lvalues is deprecate +d RawIP.xs:790: warning: use of cast expressions as lvalues is deprecate +d RawIP.xs: In function `XS_Net__RawIP_icmp_pkt_parse': RawIP.xs:823: warning: use of cast expressions as lvalues is deprecate +d RawIP.xs: In function `XS_Net__RawIP_generic_pkt_parse': RawIP.xs:863: warning: use of cast expressions as lvalues is deprecate +d RawIP.xs: In function `XS_Net__RawIP_udp_pkt_parse': RawIP.xs:897: warning: use of cast expressions as lvalues is deprecate +d RawIP.xs: In function `XS_Net__RawIP_dispatch': RawIP.xs:1289: warning: use of cast expressions as lvalues is deprecat +ed RawIP.xs: In function `XS_Net__RawIP_loop': RawIP.xs:1311: warning: use of cast expressions as lvalues is deprecat +ed make: *** [RawIP.o] Error 1 Ed Welsh The information transmitted in this e-mail is intended only for the addressee and may contain confidential and/or privileged material.

Knoppix detects a swap partition, tries to mount it and either fails or locks up. If it merely fails and goes on, life is good and Knoppix can be used to fix the machine, or attempt to. If it locks up then one would have to reboot and do the "noswap" option. Whereas a liveCD made specifically for this type of task would only try to launch a bare minimum of software. If all you want to do is check the hdd, then Knoppix is really a Rube-Goldberg machine. Sure it has all the tools and bells and whistles, but all you really need is a command line and a scandisk tool (and possibly cfdisk and mkfs). And if a person is not knowledgeable enough to do some disk analysis from the command line, then that person has absolutely no business trying to fix a broken system.

Bicycle power can be used to power a wide range of devices. I would be willing to bet that the average bicyclist could easily put out 1/10HP and quite probably more depending on a number of factors (including gear ratios). > directly, but stepping down the car battery to the > laptop battery power level might require enough > complexity that just an inverter with the existing AC > adapter might be more workable. This should be easily accomplished with a resistive series and resistance added in parallel with the laptop portion of series of the entire the circuit. The most difficult part being figuring out the effective resistance value of the laptop. Of course, one could always go the route of using the cigarette adaptors spoken of earlier, and forego the calculations. And on your latest post. The fact that your light wasn't steady might not have as much to do with constant power output as with other conditions and factors. A stationary bicycle that is properly configured should produce better output than a moving bicycle that is varying in angles relative to the road surface, rattling, bumping, climbing, descending, friction, etc. Don't forget you can get a lot more energy from a stationary bike than one that also has to power forward motion. But all that aside. A proper configuration would be for the bicycle to be used as a charging device, and the power drawn from a battery/fuel cell.

Define "real rescue disk". If your drive is fubared and swap part. is damaged, then it won't mount it. If you have a Winders PC and no swap, it won't detect or use one. Where's the problem in that? If you want to repartition or use some bit level recovery tools, use noswap. If the FAT is damaged, then you couldn't use the swap and it wouldn't be detected. For the average user, with Winders only, no special attention is req'd.

Again, find the right tool for the job. DamnSmall boots fast and has GUI editors that don't need a lot of RAM. DamnSmall does have some quirks, but they are easy to figure out. Mounting HDD partitions RW was a bit stubborn, but doable and certain functions are best done from a Root xterm or from their hacked file manager. It has some features built-in to get around problems if you know what you are doing, but not allow a newbie to do stuff by mistake. Brian Kelsay >>> Leo Mauler <> 12/30/04 02:16PM >>> True enough. I've always thought a "crawl" basically meant "a speed wherein it takes longer to open the application than it does to finish some real work on the application." KNOPPIX in 96MB means I usually type things in a CLI editor anyway, even if its in an XTerm window. KWrite or GEdit if I'm desperate for a GUI Editor.
