Enough people have wondered/asked/complained to me about this that I'm
posting this now as a public service.
IBM Model "M" keyboards are still available, *NEW*, today. They are
expensive, but they are the original design that you can use as a melee
weapon. The catch is that they don't say "IBM" or even "Lexmark" on
them. They are available for purchase from the manufacturer, Unicomp,
who can be found online at http://www.pckeyboard.com/.
You can also find some vintage NIB units from time …
[View More]to time at
http://www.clickykeyboards.com/.
There are also a number of other manufacturers now making similar, but
not quite as good, keyboards.
- CVT Inc., the maker of the Avant Stellar (I own two of them), which
is the direct descendant of the Northgate Omnikey, seems to have
restructured and no trace of their keyboard manufacturing operation can
be found online. However, Northgate keyboards are still available
new-in-box from (this is a horrible site, beware)
http://www.northgate-keyboard-repair.com/.
- The Happy Hacking keyboard (now owned by Fujitsu, apparently) is
equally comforting to some people despite having a totally different
feel. They, and many others, can be had from
http://www.elitekeyboards.com/
- Das Keyboard
- Anything using Cherry MX Green, Blue, or White keyswitches. The
"green" switches apparently are the closest anyone's come yet to
emulating the IBM/Lexmark/Unicomp switches... and they can be had in
MUCH cheaper keyboards, like the Rosewill RK-9000
(http://www.newegg.ca/Product/Product.aspx?Item=N82E16823201040 and
http://techreport.com/review/23405/rosewill-rk-9000-series-mechanical-ke
yboards-reviewed).
- And there are an increasing number (yes, again, after the big die-off
ca. 2009) of speciality manufacturers of "ergonomic" keyboards that are
making clicky keyswitches available as an option. One of the better
ones is a tiny shop in Ontario, but I can't find the name right now.

I mentioned this problem at the last round-table session, but didn't get
a solution, so I thought I'd post it here, just in case anyone has any
suggestions to offer.
I'm still seeing a whole bunch of false positives in SpamAssassin, since
an update was installed in mid-September on a CentOS 5.7 system, for a
rule called DATE_IN_FUTURE_96_Q, which is only supposed to be triggered
when the "Date:" header has a date that is 4 days to 4 month ahead of
the date in the "Received" header that …
[View More]has the _smallest_ difference in
date.
Here are the headers from the latest e-mail I've received with this
false-positive. (I've stripped out irrelevant headers, for the sake of
clarity and simplicity.)

Note that I'm calling spamd via the spamass-milter on a system running
sendmail. Note also, that in the above example, the only "Received"
header was the one generated by my own server. (I've had other false
positives, however, with multiple "Received" headers, all of which were
within seconds of the time in the "Date" header.)
Any ideas?

Does anyone know of a graphical folder tree visualization tool?
Specifically one that can recognize
symbolic links, and can stop at a specified folder depth?

Is it possible to aggregate DSL lines, to combine them to get X-times the
bandwidth on a single link? In this situation, I control both ends, the
DSLAM and the DSL modem side on the other end of some POTS runs (CAT3-ish
I assume, or worse).
Note, I don't want load balancing or fancy routing/sharing. I need double
(or more) the bandwidth for a single application (single TCP connection).
If required, we can have linux/bsd boxes we control at either end of the
links.
If it's not possible,…
[View More] does anyone have any other ideas for somehow getting
better bandwidth out of 500m POTS wires (quantity 4)?
Thanks!

Are there any reasons for not considering commercial (backbone) wireless
gear for connecting points. It is a common practice for multi-building
sites where project funds (or other constraints) prevent wired/fibre
connections between buildings.

Further to my recommendation to watch "Mr. Robot":
For those that don't get Showcase in your Shaw cable package, it seems
that you can watch Mr. Robot on-line for free here:
http://www.showcase.ca/video#mrrobot/video
New episodes every Friday!
What's the cheapest option for a Winnipeg business to get decent
(especially upload) internet access when they aren't in a Shaw area (but
are in MTS). Right now they have MTS crappy like 5Mbps down and 400kbps
up. It's horrible.
We'd be fine with 5 or 10 (or more) down, but we want at least 2 up. The
more up in our pricerange the better. Monthly traffic will be quite low
in both directions, but we get large-demand bursts.
Price range is $40-$80/month. They are willing to pay (a bit) …
[View More]more
upfront to save on the monthly fee, if required.
They need zero extra features (email boxes, web space, a/v, domain, etc),
they just need faster internet. Lower latency than what garbage MTS gives
would be better too. I already checked with MTS and what they want for
more upload bw is way too much (compared to what Shaw charges).
Thanks!

I mentioned Linux capabilities (setcap/getcap commands) briefly during
last night's round-table session, and Trevor mentioned that he thought
that recent Fedora releases had eliminated the use of setuid-root
binaries in favour of capabilities-based binaries. (That's the stated
goal, in any case.)
Not sure about the very latest Fedora/Rawhide releases, but here are the
numbers on a Fedora 21 host I was able to quickly check...
$ getcap /usr/*bin/*|wc -l
10
$ ls -l /usr/*bin/*|grep '^...s'…
[View More]|wc -l
21
$ ls -l /usr/*bin/*|grep '^......s'|wc -l
7
$
All of the setuid binaries (in the second command) are setuid-root. The
setgid binaries (last command) have varying group ID's.
For comparison, here are the numbers on an EL7 host...
$ getcap /usr/*bin/*|wc -l
8
$ ls -l /usr/*bin/*|grep '^...s'|wc -l
23
$ ls -l /usr/*bin/*|grep '^......s'|wc -l
9
$
The difference in counts between the two hosts likely has more to do
with specific packages loaded than with actual differences in the
distros, though.
Note that Linux capabilities are intended to grant only specific
kernel-based rights that were otherwise restricted to root, so it likely
won't eliminate all setuid/setgid use cases, without some more drastic
coding solutions.

Someone mentioned a web site offering a different free e-book each day,
on various tech topics. Here's the correct URL for the site...
