Python has some language features that one might never use, but then
one day you come across them in some other code and need to know what
they do. The following fragments (see the reply by Xoanan on this page) are
To determine the intersection between two lists "list1" and "list2":
intersection = filter(lambda x:x in list1, list2)
To determine the union between two lists "list1" and "list2":
union = list1 + filter(lambda x:x not in list1, list2)
To determine the difference between two lists "list1" and "list2":
difference = filter(lambda x:x in list2, list1)
To determine the distinct elements, those not in common between two
lists "list1" and "list2":
distinct = filter(lambda x:x in not list2, list1) + filter(lambda x:x in not list1, list2)
A discussion of the various ways of extracting the
unique elements from a list
From time to time you might encounter a list which contains some lists,
and you want to flatten this into a single list of simple elements.
artical talks about two ways to do this. Perhaps the more readible
method is with the nested list comprehensions:
nested = [[1,2,3], [4,5], ]
flatList = [x for sub in nested for x in sub]
[1, 2, 3, 4, 5, 6]
this works by the first "for" loop (for
sub in nested) iterating over the top list and on each iteration
picking up a sublist and placing a reference to it in "sub", then the
second for loop (for x in sub)
runs and picks up the selected sub list and iterates over it, placing
each element of it in x. A list of all the individual values that x
takes is built up by the [x ...]
construct. A limitation with this is that all the elements in the
outer list must support iteration (i.e. be lists, tupples or something
else list-like), so you cannot have a simple scalar element in the

Based on CDN$20 per cartridge (current pricing seems to be in the $15 -
$19 range) this would work out as $0.24 per print. What the poster did
not mention was what the print size was... in a follow up it was said
to be 8x10 on standard printer settings, using Canon Photo Paper Pro
Here is some more information:
I purchased the i9900
about 6 weeks ago
to replace my S9000. The
S9000 is no slouch and a top rated printer from 2 years ago but i9900
is much better. I now shoot with a Canon 10D and Canon L lenses even
though I have thousands of transparencies to scan on a Canon FS4000US
film scanner. The 10D was purchased just prior to a trip to Rome where
I shot about 1000 images.
I just finished
assembling 170 of
the best Rome images into an album using Canon PhotoRecord software
that comes with most Canon digital products. I printed the album on
both Epson dual-sided matte paper and Pictorico dual-sided semi-gloss
paper. The results are amazing. Both papers work extremely well with
the i9900 although they each have their own subtle tinting difference.
This can be corrected easily with color adjustment through the printer
driver. Printing the entire album on the dualsided 8.5 x 11 stock (68
pages total) used no more than half of some of the ink cartridges and
almost none of the red and green. People who have viewed the album are
stunned and amazed with the quality and can't believe it came from an
inkjet printer. The color punch and tone is incredible and the level of
detail and resolution equals or exceeds wet chemistry printing. If you
want to see dots you'll need at least a 4X loupe and there is
absolutely no banding.
It is a mistake to
not consider this
printer because of the limited selection of Canon papers. Epson papers
work extremely well on the Canon printers as do Pictorico, Mitsubishi
and Konica. These are the only papers I've had the opportunity to try.
Needless to say, I am very happy
I bought this printer.

A review of the HP Photosmart A626, this has a built in set of card readers and a 4.8 inch LCD (which in Sept'07 was nearly the largest display on any such printer - the HP Photosmart A826 has a larger 7 inch display) for photo selection and editing (including cropping). This unit prints 4x6 and 5x7 photos, so is a bit limited, but for the Scrap Booker and Grandma type user this may be just the right set of features.
PrinterInfo.com has a lot of information and reviews on printers.  It seems to be relatively easy
to install games on an XP Pro box under
the administrator account, and I seem to be having pretty good success
at getting them to run. However, they will often not work under other
accounts on the same machine. Part of the trick at getting them to run
seems to be to give the other accounts "Power User" group rights.
However my old NT 4.0 Domain server does not have the "Power users"
group, so it looked for a while like I would have to create local
machine accounts with membership in this group. A bit of web searching
turned up this
page that suggested there was a way to make the NT4 domain user
group appear to be called the power user group and this would have the
same permissions. The trick was to go to the workstation where the
power user group is needed (actually it sounds like this will apply to
all machines) and execute this command:
net localgroup "power users" /add "DOMAIN\Domain Users"
once I did this it became possible to install software as a regular
user and a lot of the programs that refused to run under other accounts
will now work.
When rebuilding an XP box that had developed a corrupted network stack
I was able to do a back and restore to another hard disk using Acronis'
drive imaging software. Then, I was able to safely experiment with the
copy until I had figured out what I needed to do. As part of the final
step of rebuilding this machine I used the
Linux Knoppix distribution to:
- create a FAT32 partition on the spare space on the test
(Windows XP Home will only let you create NTFS partitions)
copy a bunch of files off the original NTFS boot disk
(which was reinstalled in the computer as a second drive) onto the FAT32
partition. I did this because under XP an administrator of the newly
installed operating system cannot get access to all the files from the
original drive (which is certainly not the case with Windows NT, but
may also be true for Windows 2000). Once you are in Linux you appear to
have access to all files again.
How to uninstall
hotfix or a service pack (perhaps that Windows Update has
installed) that is causing the computer not to boot. Use the recovery console (boot from the
Windows installation CD to get this) and do a DIR $* to see the various hot fix
uninstall directories. Then, for those that were created on the suspect
date, CD into each in turn and execute the uninstall batch file with
the command: BATCH spuninst.txt.
After doing one of these you should reboot (by using the EXIT command) to see if it fixed the
problem, and if not, proceed with the next patch. On 13-Oct-06 a set of
Windows updates messed up one of my Windows XP Pro boxes (KB922819,
KB923191, KB923414, KB924191, KB924496 to be precise). I used
this approach to remove them, but the same problem remained. On
the following day while I was copying files off the afflicted machine
to prepare to rebuild/repair it, Windows Update redownloaded the
updates I had removed. I let it reinstall them and found that
this time the updates worked properly. So I suspect that something went
wrong in the first update that the second attempt corrected.
Also see this for
what to do if Windows Update keeps downloading the same patch again and

Windows Dynamic disks (described in this article: KB222189 - note
this article does describe an "import" function that is provided to
allow you to move a dynamic disk from one system to another) cannot be
moved from one system to another readily. This knowledge base article: KB232463,
mentions this in the context of laptops, but I have run into this while
trying to move dynamic-type disks from an older Win2K machine to its
replacement WinXP box (when I did this the disk was shown as
"foreign"). Probably best to stick with the basic disk type, unless you
are really needing to make use of the new features of dynamic disks
(for example to provide a RAID file system). It also appears that you
cannot put a dynamic disk into a USB drive case and still access its
contents (the article KB254105 confirms
this is the case) - probably for similar reasons relating to the disk
partition database, as once the disk is USB attached it could be
attached to any number of machines and this database is not designed to
handle this. Other articles on dynamic disks:

Windows Services can be made to be dependent on other services being
started first. Modifying these dependencies are discussed in KB193888, the
TechNet article: Understanding
Windows Services Architecture goes into this in more depth, it also
states that the dependencies are used during the stopping of services
too. If you are installing a custom service that needs internet
connectivity and also access to files on network drive shares then this
article on installing
Apache as a Windows Service, may help. It identifies the following
other services that your service should be dependent on:

ignores the service dependency tree and tells all services to shut down
at the same time (not in the reverse of the order that they were
There is a way to download all the windows updates

It is possible for Windows XP to get into a state where you cannot
logout (log off), shut down or reboot the computer from the start menu
(or by pressing ctrl+alt+del), there is a way to "force" the action
that you can try is this happens to you (rather than just hitting the
reset or power button). Get to the log off prompt and then hold down a
CTRL key while clicking on the "OK" button. This should force the
logout to take place, and then, from the login screen you can do a shut
down. The same trick also works for doing a forced shutdown or reboot,
but in the case I tried I was able to do the forced logout and then was
able to do a normal shut down, which seems a bit safer that just doing
a forced shutdown.
How to get Windows XP File Search to Really Work (again).
The search function of Windows XP (from the start menu "Search") is by
default not set to search the contents of most files. In order to turn
this on you can follow the steps in method #2 on
this page. A similar writeup exists in Microsoft's KB309173.
If you have ever used the "search for text in files" function and it
has failed to find what you were looking for, but you know that the
search should have worked it is probably because the behavior of the
searching changed greatly between Windows 2000 and Windows XP. By
default Windows 2000 would search in all files, but Windows XP will
only search in certain "known" file types (probably .txt. and .doc and
not much else). The fix for this is quite simple, though remarkably
hard to find. Here's what to do:
note that despite the fact this setting is controlled through the
Indexing Service, you do not need to start the Indexing Service running
for this to work.
- open the control panel
then go to administrative tools and open the "Computer
Management" application, set the display to show both the tree view (on
the left) and details list on the right, (the 4th icon from the left on
the tool bar) and the do the following steps in the tree view
under "Computer Management (Local)" you will find "Services and
Applications", and then "Indexing Service"
do a right click on "Indexing Service" and select "Properties"
from the popup menu
the "Indexing Service Properties" window will appear, this has
two tabs, in the tab called "Generation" you will find a check box
labeled "Index files with unknown extensions", you need to check this
and then click the OK button and that is it

While such a system could be of great benefit to patients (the users) by centralizing all their records and ensuring whole sections don't get lost when a doctor's office moves or closes, and it could also be of great benefit for researchers who could get anonymized access to query the system, there is still the risk that such a system could be very tempting to Big Brother and so it's privacy should also be shielded by strong acts of law.

statement: "Due to proprietary mechanical design, MSI only guarantees
the compatibility of the MEGA PC with MSI's own Optical Storage
Devices". Another thing that bothers me is in Motherboards.org's
review they note that the hard drive mounting bracket actually
positions the hard drive upsidedown
and suggest drilling a new set of mounting holes to correct this.
by SFF TECH, they also have a forum with some feedback about it and a knowledge

FlexATX or MicroATX chassis, perhaps with modification of the mounting
hole positions. Also, the mini-ITX supports both ITX and ATX compliant
power supplies) .
Here are a number of neat
case projects built around this sort of motherboard. The Lex
case (reviewed here)
is based on the VIA Mini-ITX. The mini-ITX format could also be used to
your own supercomputer cluster. Or you can fit an entire PC
into a Windows XP retail box - not your typical computer case, but the
artical has some interesting custom case building ideas.
Here's a good overview of a lot of the various
boards and options available now in mini-ITX.

In Jan'07 Via announced their Pico-ITX
super small motherboard, only 3.9x2.8 inches, discussed here
on Slashdot. This board has most of its IO on pin headers (just the LAN
and VGA are on conventional connectors). I would have thought that this
is a step backwards, and some USB and audio (and perhaps also a
composite, or component or DVI video) connectors on the board would
have made a lot of sense for the typical sort of things this board
would be used for. Here's one stuffed

around an AMD chipset.
Intel is also going to have a DTX
motherboard called the D201GGV, should be available in June'07.  ASUS all the experience I
have had with ASUS motherboards has been good. Good single and dual processor

beyond 1280x1024 resolution. They had some problems installing the NT
drivers, but that's pretty common. In late 2004 AOpen introduced a motherboard
that uses the Pentium-M (mobile) chip, this allows one to build a much
more power-efficient workstation as one of these chips uses between 3W
and 20W when running instead of the more typical 100W of the current
Pentium-4 and Athlon processors.

Intel's hyperthreading system may actually reduce
the performance of heavily threaded applications
in Jun'06 AMD announced their 4x4 chips, which really will be dual
processor, dual core motherboards - so a 4 CPU "consumer"
workstation will soon be possible. These are being targeted at gamers
as they will support a pair of dual GPU graphics cards (for 4 times the
rendering power). I wonder what size of power supply you'll need to run
a high end system?
In Jun'06 Intel started showing their new Conroe CPU, this

Nov'06, this will run in existing 775 socket motherboards and looks
like it will bring quad-CPU functionality to the desktop. Here is a preview
of the performance that can be expected. The Core 2 Quad got launched
in early Jan'07.
In Feb'07 AMD
showed their new Barcelona quad-core CPU, the unique thing about
this is that each core also has a vector math processor.
In Aug'07 Tilera
announced their new 64 core processor the TILE64. While this is a
RISC chip (rather than an x86 processor) it may make its way to the
desktop by some Linux variant.
 In Sept'07 Toshiba
announced their SpurEngine video processing chip, this is based on
the Sony Cell processor technology used in the PS3, it looks like they
are going to integrate this into some of their future laptops to give
them a boost in the video editing (trans-coding) department. This could
be a significant advancement, I wonder if anyone is going to make a
PCI card to allow a video processing accelerator to be plugged into
existing systems. This could also help with power consumption, as its
possible that one of these chips could consume less energy that a
general purpose CPU to do the same overall task, which would be good
for laptops. LeadTek's HPVC1100 puts a SpursEngine in a small external enclosure for connection to a laptop (or perhaps some other computer).
 ASUS's new P5E3 Deluxe motherboard (reviewed here) will include an instant-on Linux desktop environment built into the BIOS so the computer can even be used for web browsing and VoIP without booting into a full operating system. Earlier attempts at this sort of thing have been limited to CD Audio and DVD play back. Discussed here on Slashdot. Engadget has some more information about this. In mid-2008 ASUS announced that it intends to start shipping Splashtop on all its motherboards.

electric cars, 0-60 in 3.7 seconds from an very expensive set of

 Here's a bus that uses
in-wheel electric motors for drive, along with a battery pack that
is continuously topped up by a small diesel generator system that runs
continuously. They seem to be making a big deal of placing the motors
in the wheels, but I think that's been done before in big construction
vehicles (wavecrest is
doing this in bicycles). While the in-wheel motors sound like a great
thing because they eliminate the weight and inefficiency of the drive
train, they may well be less desirable because they increase the mass
of the wheels (requiring suspension redesign, possibly offsetting some
of the drive train weight savings - older racing cars used to place the
brakes at the end of the drive shafts furtherst from the wheels for
this reason, this was called "in-board brakes"), they now expose the
motors to a much worse environment (lots of road shock, water and
debris), and installing a liquid cooling system on the motors is now
more difficult (which may not be a big problem if they get enough air
cooling, but it eliminates using the motor's waste heat to warm the
passenger compartment in the winter...). Also, given you now have these
larger rotating masses there will be more rotational inertia in the
vehicle (which means slower acceleration and braking, but this might
not be significant). E-Traction is going to modify a number of buses to use in-wheel electric motors along with a hybrid diesel-electric power system, they are claiming up to 50% better fuel economy that normal buses.

make this strange material, scientists start with a liquid alcohol
like ethanol and mix it with silicon dioxide to form a gel. Then,
through a process called supercritical drying, the alcohol is forced
out of the gel, typically with high-pressure carbon dioxide. With this
drying process, the gel does not collapse or lose its volume. It
appears holographic because the silicon dioxide scatters shorter
wavelengths of light much like air in the daytime sky.

The stated power does not seem reasonable for such a large project, as 4 square miles is just over 10 square km, and each square km has about 1GW of solar radiation (1000W/m2 x 1000m x 1000m = 1GW), so 200MW/10GW = 0.02 or only a 2% collection efficiency which seems rather low.

from wind, an Australian claims to have invented a windmill that

the air (which will chill it) and one could just take a conventional
windmill, use it to drive a compressor (which will compress a stream of
air), then cool the compressed air back to ambient temperature (perhaps
using the waste heat to heat your house or hot water) and then expand
the compressed air back to normal atmospheric pressure and a lower
temperature, which will cause the water in it to condense (and cause
the expansion nozzle to get cold causing water vapour in the normal air
passing over the outside of the nozzle to condense). This is pretty
much the standard thermodynamic cycle used in refrigerators around the
world, except in those a special fluid is used that switches state from
liquid to gas and back as it goes around the cycle making the process

Wind Power in Cold Stores, this is really a case of intelligent
load averaging, and thus, swapping some conventional power requirements
for wind generated power. For one to really make the claim of "storing
power" one should be able to place energy into the storage device and
then return some of that energy back to its original form for later
use. That said, this is a good example of "low-hanging fruit", there
are probably plenty of power users that could be tailored to make use
of alternative power sources when those are abundant (for example
commercial green houses, swimming pool heating, ice rink cooling...).

separator module, this will take methane and separate the hydrogen
from it, presumably producing CO or CO2 as a byproduct along with waste
heat (which can probably be used for space heating or hot water
heating), the hydrogen gas can then be used in a fuel cell to produce
electrical power for the house, to charge an electric car or could be
bottled for use in a hydrogen fueld car. The advantage with this sort
of approach is that enables a more efficient use of fossil fuel by
allowing the waste heat to be used for household purposes. Since a
central power plant that burns fossil fuel to produce steam to turn a
turbine to turn a generator to produce electricity which must then be
shipped some distance (during which some energy is lost) cannot be more
than about 30% efficient, most (about 2/3rds) of the fuel that it
consumes is wasted as heat - so for people who need space heating and
hot water heating using this waste heat (a process called
co-generation) instead of throwing it away is a big gain.

  FAFCO makes solar hot water systems, included ones that self-drain when they would not be producing any useful water heating.  Citizenrē implements solar solutions for home owners. Their business model is a bit different, they purchase, install and then maintain the system on your house. In return you buy the electricity it produces at some pre-determined rate (that is to be at, or below, your current electric rate).  Honda has set up a new company: Honda Soltec, to develop and manufacture solar cells.  AMD has introduced some new 45-watt processors, which would be useful in lower power appliance (i.e. such as DVR) computers that don't need super-fast processors but do get a lot of run time.  Via's vm7700 is a compact computer built into a case that can bolt onto the back of any standard VESA type LCD monitor. The screws that hold the the PC in place actually go all the way through it, which makes mounting it to the back of the monitor very easy. Now that this approach has been publicized I would expect to see some other third party case manufacturers start making similar boxes. One potential application of this sort of thing would be as a DVR PC, allowing the PC and all its cables to easily be hidden behind a large flat panel TV system.   Is Google trademarking Google PC? If so, why?  HDTV Supply has a lot of video cables and converter devices.  A prototype 700MHz WiFi card has been announced by Ubiquiti, this has been tested with a range of up to 31 miles at 50Mbps. With the potential of such long ranges its easy to see why the 700MHz auction that will happen in Jan'08 may be very important to the future of mobile broad band.  The Samsung SPH-9200 UMPC (the cute flip and fold split keyboard design) is getting closer, its manual has been leaked.  SYSTAT makes statistical and curve fitting data analysis software.

Breaking the gigapixel
barrier, using a 6MP camera and stitching a large number of images
together. The result is quite amazing. This also has some (simulated)
comparison between this resolution and other real resolutions. This
sort of resolution is not really so far away as one might think,
consider that the current resolution size is about 10MP, so multiply
this by just 100 and you have 1GP. Now a factor of a hundred sounds a
lot, but since sensors are not lines, they cover an area, so all that
needs to be done is to multiply the number of sensors in each dimension
by a factor of 10. This could be done today by making the sensor
larger, roughly 4 to 8 inches across would do it (but then you're
looking at a pretty big camera - but such large format cameras have
been used before), or else if the sensor was made more dense we would
have to wait about 6 to 9 years (circuits shrink by about a factor of 2
every 2 to 3 years). Sensor noise might be one limiting factor here,
but I would think we would hit some sort of optical limit before this

The effect of megapixel counts and print sizes, this
article demonstrates that 5Meg (or more) can produce apparantly
identical results at a 16x20 print size. In my experience with printing
8MP images (all shot in JPEG) from my Minolta A2 at 13x19" size (on a
Canon i9900 printer), its pretty much impossible to see any evidence of
their digital origins - about the only chance is if you can pick out a
sharp edge between a light and a dark object, then you might be able to
make out a narrow band of lighter area intruding onto the dark region
(which is probably a JPEG artifact). I have done a 13x19 print from the
Minolta A2 of trees in autumn standing in a field of long dry grass,
and even on the grass I cannot make out stair casing. I did some
test prints once from my 3MP Canon G1 and printed a 16x20 as a tiled
8x10 set (which means that the printed pixels were about 100 pixels per
inch) and in those you could see pixelization on the edges of things,
but if you viewed from a reasonable distance you could not see them. My
conclusion is that 5MP should be good enough for most people,
especially if you get a camera with a larger sensor to reduce the
sensor noise. Of course if one is purchasing a camera with less than
about a 5x optical zoom then more pixels might well be useful to allow
for additional cropping before printing.

The Panasonic DMR-E85H is quite a nice DVR, it has a 120GB drive
and the TV Guide on-screen function (which works quite well). It looks
like this was available in the 2003-2005 timeframe and has been
replaced by some other models. From time to time it will "crash" (for
me this ocasionally happens when I insert a blank DVD-R to do some
dubbing, maybe about once a month), sometimes when it crashes it looses
the contents of the TV Guide memory buffer, so you may have to wait for
a day or two before the TV Guide is available again. A number of people
have reported U99 errors (especially with use of the divide function),
I've only seen this problem once. See this artical for some
discussion of the U99 issue, including a remark about the owner having
put a 160GB drive into the DVR, but the DVR only used the first 120GB
of it (maybe it would be possible to remove the drive after it has been
formatted and then extend the partition?), there is also discussion of

The Toshiba RD-XS34

features the Panasonic DMR-E85H has, the main one being that when you
are in a contents view mode (where there are a number of thumbnails
representing individual shows or chapters) these are just static images
on the Toshiba, while on the Panasonic these actually will show the
video. The Toshiba does have one major advantage in that if the unit is
recording and you go to watch another previously recorded show at the
same time, the Toshiba will let you set chapter marks in this show, but
the Panasonic will not.

 A potential blood test for Alzheimer's disease.  Beaming solar power from space in the form of microwaves has been talked about in the past for a long time, but now it seems to be getting more attention. The collection efficiency can be improved (versus land-based) because there are no losses due to clouds or atmospheric pollution and potentially a collector can be kept in full sunlight 24 hours a day (though this would mean it needs to transmit its output to different sites on earth as the world turns) the raw cost per watt would be less for space based collectors than ground based ones. Of course, that would get massively reversed once the cost of lifting the collectors into space is factored in.

The real drive behind this might be the need for power in the military (though that does not make a lot of sense as the power will be off during the night, and the batteries the military would need to store power for use overnight would likely be bigger than the oil fueled generators they replace). It might be the military sees this as a way to get a new weapon in the sky, consider their recent work with the "pain ray", a microwave gun that causes intense pain by stimulating the nerves of the skin, perhaps such satellites (which use microwaves to relay their collected power to the ground) could do double duty and be used to cover large areas of a battlefield with pain rays, thus, knocking enemy troops out of action prior to an attack.

The UM150 EV-DO USB modem for wireless internet.  SanDisk is working hard at figuring out more ways to increase the demand for flash memory, their new TakeTV is an 8GB USB drive that enables video playback. Apparently it has a docking station that provides video output (though why you need such a bulky memory stick for this is still unclear - perhaps they have put the video chips into the same package as the flash drive rather than putting them into the docking station)? Engadget takes a more detailed look at it here. I think they are still missing the best market opportunities by not including support for hi-def playback and by not including support for playback on DVI-D LCD panels (then this could be used to make a large photo frame out of an LCD panel). Switched On discusses the TakeTV.
Well it didn't take long for this to die, it lasted from about 30-Oct-07 to 15-May-08. Let's hope SanDisk learned something here and come back to the table with something capable of playing HiDef.

CNet's Rory Reid got his hands on it and quite liked it, a Slashdot discussion of this review revealed that ZDNet was to have reviewed the machine after CNet, but that CNet had messed it up by trying (and failing) to install XP on it. However, Rupert Goodwins the the ZDNet reviewer then fixed the problem by installing the new Ubuntu 7.10 Gutsy Gibbon release on it. Since the standard Ubuntu installed with only minor issues I'm guessing that this little laptop might receive a lot of attention from the Linux community which should be a good thing for it. There is also an unofficial Eee PC forum at www.eeeuser.com along with lots more news and some unofficial specs (like the VGA port supports up to 1600x1280).

AVSMedia sells video format
conversion software, as well as a pretty decent video editing
(which includes the ability to include still images and do simulated
pans and zooms within them). They have a fully functional
try-before-buy version that just puts a logo in the middle of the
output, so its easy to test to see if it will work for you. You can use
this to create DVDs from source material that is in 16x9 aspect ratio,
the trick with this is once you have placed the clip on the time line,
right click to summon the properties menu and then from the properties
dialogue select the "aspect" tab and set 4:3 as the "video proportion"
(which seems counter intuitive). When you setup the initial project you
should also set it to 4:3 aspect ratio, even though what you are trying
to do is to make a 16:9 letter boxed DVD.

DVD-R and DVD-RAM, but that's not too bad - however, almost all the
competition also write to DVD+/-RW media. When it writes to DVD-RAM it

consider that a Windows XP with Office can still be comfortably
installed on a 10GB disk, so it might well be feasible to run a Windows
desktop off a flash card, and now SanDisk has read and write speeds up
to 20MB/sec this might well be quite speedy.
Kingston has a secure flash drive that will automatically
erase your data after 25 failed password attempts.

- You will probably need to set some program options first, in the "General Parameters" select "Queue to batch clears cut list" and set the "Editing Mode" to "Scene Mode".
- enter the Batch Manager, and select a destination folder,
then enter a "_" (underscore) into the "destination modifier" field, finally
hit the "Done" button
- now pick the scenes you want in each separate file (you
can select several per file if you want), by finding the start of the
scene, clicking on the "Sel. End" button, then finding the scene's end
and clicking on the "Sel. End" button and at last clicking on the "Add
Selection" button. Repeat as needed.
- once your list of scenes is complete you hit the CTRL+B
key (or use the File / Add Edits to Batch Queue... menu item)
- a dialogue will appear that shows you the file name it
will save those scenes to, this should be in the destination directory you
selected, the file name should start with the original file's name and
then have an "_nnn" extension, where "nnn" is a number that starts with
001 and automatically increases each time you hit CTRL+B. Answer "OK"
to the dialogue if the name is correct.
- once you have finished your selections you select the
Tools / Start Batch Manager menu item again, check the "Run Silently" check box
(this doesn't seem to do much) and then press the "Save and Execute"
button and it will build the new set of scene files without needing
further user interaction.
