SpamAssassin false positives on DATE_IN_FUTURE_96_Q?
by Gilbert E. Detillieux 23 Feb '16

23 Feb '16

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 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.) From topfivestories(a)messagent.itworldcanada.com Mon Nov 14 07:50:13 2011 Received: from mail.messagent.itworldcanada.com (mail.messagent.itworldcanada.com [207.112.10.80]) by palladium.cs.umanitoba.ca (8.13.8/8.13.8) with SMTP id pAEDoAxV028594 for <gedetil(a)cs.umanitoba.ca>; Mon, 14 Nov 2011 07:50:12 -0600 Date: Mon, 14 Nov 2011 08:50:13 -0500 X-Spam-Status: No, score=-0.3 required=5.0 tests=BAYES_00,DATE_IN_FUTURE_96_Q, HTML_MESSAGE,RP_MATCHES_RCVD autolearn=no version=3.3.1 X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on palladium.cs.umanitoba.ca 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? -- Gilbert E.

Fw: [Info-nano] ANNOUNCEMENT: Exciting news about our acquisition by VIM [PATCH]
by Trevor Cordes 24 Jul '13

24 Jul '13

Funny, from the Nano mailing list on Apr 1: Begin forwarded message: Date: Mon, 1 Apr 2013 04:20:33 -0400 From: Chris Allegretta <chrisa(a)asty.org> To: info-nano(a)gnu.org, nano-devel(a)gnu.org Subject: [Info-nano] ANNOUNCEMENT: Exciting news about our acquisition by VIM [PATCH] Hello, First, I want to give a hearty thank you to all our users and developers who have been using nano all this time. I wanted you let you know that I received word from the FSF legal offices that we have been acquired by VIM, hopefully putting to rest a lot of bad blood between the text editor factions. For those of you who have been keeping up with development, the key bindings code and vim-style locking were probably dead giveaways that this was going to happen soon, and congrats to everyone who figured this out before today. For those of you who have contributed to the code base, the details of this deal are as follows: - All right, likenesses and the nano domain become the property of the VIM Development Corporation LLC OMG WTF BBQ - Our recursive acronym Nano's Another Editor, is being changed to the classic vi tagline, "What Mode Am I In Again??" In exchange, the following compensation is being offered: - One thousand "vim rules" bumper stickers (FCFS on these!) - At least 150 coupons for a free KFC Double Down. Must give your name as "vim" when you order. No free refills. - We will be recognized on a special plaque, near home plate at a to-be-announced vim-owned sports stadium (once a few more tech companies go under or are bought by Google). - That happy feeling that we didn't end up owned by emacs The attached patch is a sneak peak at the transition plan we will be using in the development versions of nano. Please see the following timetable for transition: - Starting today with this patch, through versions 2.4.99pl47-omg[ac]1, nano will continue to default to what is effectively vim's Insert Mode. You can get into insert mode via Esc, or the usual method of pressing random keys until it works. - As of version 2.5.0, Command Mode will become the default, but we will retain backward compatibility with legacy nano commands - In version 2.7.0, we will all be dead by then so don't worry about it. Have you seen how long just point releases take me? :P Thank you again for using our editor, and I'm looking forward to seeing all those bumper stickers in the KFC parking lot. Eat up friends, we've all earned it!

I have a customer complaining. She's using Facebook. Her friend bought a refurbished laptop from me. I ran multiple diagnostics, replaced parts that didn't work. Reformatted the hard drive, installed a fresh copy of Windows XP Professional. Applied all updates. Installed Flash Player, Microsoft Security Essentials. Both IE 8, and the latest Firefox. Added Ghostery, and Flash for Firefox. Wireless network: WiFi-B. Now she complains the laptop is "freezing up". Rather than wait, she powers it down. I'm afraid of file system damage. This isn't the first time she came to me. And that laptop was not intended for her. Her last complaint was the wireless network "didn't work". It turned out she had no clue how to configure a router. I had to go over there and do it for her. She didn't know any of the router's passwords, I had to reset everything. I left with everything working. Now she's complaining it "freezes up". I'm afraid I lost patience and told her it's because of Facebook. But she's unapologetic, demanding I fix it. Again, that laptop was not intended for her. She needs something higher performance. That laptop was intended for the customer to whom it was sold. But now she's using it. Any recommendations? Thanks, Rob Dyck

Does anyone know who I would contact at Manitoba e-Health about the fact their outbound email is somewhat broken? Specifically, the auto-added disclaimer block creates very weird MIME that most of my mail programs don’t decode properly. Thanks, -Adam Thompson athompso(a)athompso.net <mailto:athompso@athompso.net>

SSD warranty - curious
by Trevor Cordes 04 Jul '13

04 Jul '13

Just got some new Samsung 840 series SSDs in stock and read the little included warranty booklet (on dead trees). It's the first I've seen to include bytes-written count as a warranty parameter! It states you get 3-years OR "when the SSD has exceeded its TBW (Total Bytes Written, though some websites call this Terabytes Written, but those are 2 hugely different things!) threshold as may be indicated by Samsung's Magician Software", whichever comes first. Not a bad idea, really, although: a) How the heck can we as users estimate how many bytes we're going to write in the average year, even within 2 orders of magnitude? b) I assume the "Magician Software" will not run on linux/bsd. Their 840 PRO series gives a 5-year warranty and what sounds like a higher TBW. Now that Intel is moving to 1 and 3-year warranties, and Samsung drives so far don't sound (in reviews/comments) like total garbage, they might be worth looking at. Looking at their web site, I see some conflicting information. http://www.samsung.com/global/business/semiconductor/minisite/SSD/global/ht… says "Samsung is so confident that a typical client-PC user will never be able to exhaust the lifespan of the drive that it is guaranteeing its SSDs for unlimited mileage - there are no workload restrictions in the 840 Series’ 3-year limited warranty." Huh? Doesn't that contradict the dead tree in my hands? You can see a copy of the dead tree here: http://www.samsung.com/global/business/semiconductor/samsungssd/warranty.ht… Nowhere can I see to find the exact for-warranty-purposes TBW number for the 840 series. Oh well. I guess the warranty is 3 years unless their RMA dept determines that you've exceeded some magic unknown threshold that probably only they know about and always works in their favor ;-)
