Comment Gmail, Outlook, Yahoo, etc? (Score 1) 106

What about the spam sent by the big email providers? It's a really interesting question what to do when you get -recurring- spam from these. (I get an offer for "Sun Microsystems User Lists" once a month from a chronic spammer sent either through Gmail or now Outlook. I report them to the abuse@xxx, but they keep on coming.) Do you blacklist a chronic spam source, that also has legitimate users? Do you quarantine everything from them, placing the burden on users/administrators to inspect and release legitimate mail from quarantine?

There are certainly lots of IP addresses that can be 'safely' rejected. Unfortunately, the growth of outsourced email makes it increasingly hard to depend on DNS information for sanity checks (e.g. there's an MX or SPF record that associates the "From" domain with the domain actually establishing the SMTP connection.)

Comment Does Ada count as 'little known'? (Score 5, Insightful) 427

Most contemporary aircraft have significant amounts of flight-critical software in Ada, some train control systems use Ada, some air traffic control systems use Ada, and of course there's a lot of Ada in US (and other country's) weapon systems. There's the SPARK subset that has been used for provably correct systems (does your software vendor provide a no-bugs warranty?). And there's production-quality code available under Open Source. http://www.adacore.com/ (no connection with AdaCore, other than I have lots of friends who work there.) All of my production code after 1980 was written in Ada. There's substantial anecdotal/unpublished evidence that shows large Ada systems have substantially lower life-cycle/software maintenance costs. Your Mileage May Vary, of course.

Submission + - Google recruits programmers based on their search habits

david.emery writes: Engaget reports that Google is soliciting developers based on Google's analysis of their search habits: http://www.engadget.com/2015/0... Seriously. If you search the right terms often enough, Google might interrupt your quest for knowledge with a question: "You're speaking our language. Up for a challenge?"

Does anyone else find this disturbing?

Well, I've been running Macs as my primary office automation/desktop (vice development) machine for 29 of the last 30 years, and haven't had these problems. And I routinely get 5 years out of my home Macs (and between 3 and 4 years from the corporate machines.)

Your mileage may vary.

Comment A significant difference between HW and SW sale (Score 4, Interesting) 318

Microsoft, since its only product is software, has to go to great lengths to protect and extend that property base. "Extend" here is Googly data mining.

Apple, on the other hand, makes money by selling you the hardware. The protection is the physical ownership of the device. You might not believe Apple when it says "we don't want your personal information", but you have to respect that they're not depending on either data or software to make the great majority of their revenue.

This may not be a popular opinion, but I trust Microsoft more than Google, Apple -way more- than Microsoft, and the NSA more than any commercial company.

Comment Get this book (Score 3, Interesting) 149

The best single book I know to get started in the hobby is Dave Frary's "Pennsylvania Railroad, Middle Division" which you can buy as a downloadable PDF here http://www.ebay.com/itm/Pennsy...

There are good videos on YouTube. Dave Frary also has some good quality DVDs on his website, http://www.mrscenery.com/

There are multiple groups on Facebook, and also some discussion boards such as http://www.railroad-line.com/ (tends to be pretty serious) and http://www.modelersforum.com/ (a bit less serious).

Finally, don't buy a cheap locomotive! There's nothing more frustrating than getting everything set up and then having your loco break.

Comment VMS' fine-grained privilege system (Score 1) 484

It was very easy to set up specific privileges for specific users/classes of users. I haven't seen anything else come close in 35 years in the business.

I also think VMS was the easiest system to administer, including a well thought out integrated help system that had the right answer for your question with minimal fuss.

The mail hosting companies are particularly delinquent in not making damn sure this is done for every "mom-and-pop.com" they host. If you're not a tech person, but run a small business doing something else, the ins and outs of this kind of thing is what you -should be getting- from an outsource mail service.

If it wasn't for Newton, we wouldn't have to eat bruised apples.
