Several people have asked me recently what hardware I would buy today for use as a home firewall.
- Partaker N3050 B5
- N3050 CPU
- no RAM (1 slot DDR3L up to 8GB)
- no SSD (room for mSATA + 2.5" SATA disk)
- 2 x gigE + wifi 802.11 b/g/n
- 2GB DDR3L RAM
- 2GB RAM
- Kingston 120GB mSATA SSD
- 120GB mSATA SSD
for a total of $176, including shipping. Links were accurate as of October 22, 2018.
This gets you a tiny box, similar in size to random commercial house router/firewall/wifi access points, which can run a standard Linux operating system with a complex firewall running at 1 Gb/s in and out, more RAM than strictly necessary, and an SSD which is both very large (and therefore can last a very long time) and boot the system quickly enough that you can do a reboot without losing TCP sessions.
I would also recommend a medium-sized USB thumb drive to set up as an emergency booting and backup device. Call it another $15 or so.

All email disclaimers are utterly useless – except, possibly, one that a lawyer sends you that, on that particular message, reminds you that you are not in a privileged relationship.
Here’s the proof:

One problem: we have built an immense network of supercomputers that is essentially a Commons. An abuse of this Commons that would be ridiculously unprofitable if it had to be carried out by humans – say, an expected return of one one-hundredth cent per attempt – is highly attractive to unscrupulous actors …

Someone on the
debian-user list just discovered that
gpt partitioning allows you to put 128 partitions on a disk. They got really excited at the granularity that would allow. They weren’t thinking about the exciting maintenance procedures that would inevitably follow – not enough space here, too much space there …

In ‘Lies, Damned Lies and Benchmarks’ (2014) I wrote about varying measures of CPU power versus perception of speed, and concluded that there were no order-of-magnitude differences in affordable CPUs. Three and a half years later, there ought to be some change in the market. What’s the best bang-for-the-buck …

The price for using a math library developed by Foobar Corporation is $10,000 plus 1% of the sale price of your product, or whatever you negotiate with them.
The price for using a GPL’d math library is that you must license your source code under the GPL as well.
The price for using an LGPL’d math library is distributing the source for the library along with your product. If you modify the library itself, then that falls back to the GPL.
In no case are you getting something for nothing. It’s just that the cost of using GPL’d software isn’t usually in dollars, but in contributions of more software.

Your company probably needs a librarian. Maybe more than one.
A modern librarian selects, installs, configures and administrates knowledge management software. They are experts in organizational methods and search techniques.
A librarian may take in paper documents and convert them to electronic formats. Everything gets stored, indexed, and made searchable …
