Centralized facilities are easier to manage. Centralized facilities are easier to control.
Distributed facilities are harder to manage, harder to control.
Centralized facilities need expensive, difficult redundancies to maintain function during a partial outage. Distributed facilities need coordination.
Centralized is cheaper than distributed if you don’t pay for the things that can make it reliable.

This is a reminder that spinning storage is still useful for large data dumps, media, backups, and other bulky things that you don’t need to change continuously.
But mostly, it’s cost-effective. The two current sweet spots for capacity/performance (assuming brand-name, non-sale, 7200RPM SATA3 3.5" disks) are at 4TB (about $75) and 10TB (about $270).
I also remind you that you want RAID for reliability, but it’s not backup by itself.

Via Rick Thomas on the Debian Users mailing list:
In any case, the solution I came up with is
apt-get --purge install -y sysvinit-core dbus- glib-networking- libgtk-3-0- apt-get --purge autoremove
Note the trailing minus-signs on dbus- glib-networking- libgtk-3-0- These packages need to be deleted in the same pass as sysvinit-core …

I recently ordered a dozen things from Amazon from six vendors. All the things were pretty technical – ethernet switches, fiber optic cables, transceivers, things like that. This is normal.
Four of the six vendors asked me to review their products. Two asked me multiple times over the same order.
Here’s my policy, and I urge you to consider the same one:
I will only leave a review on a commerce site if I have an unusual experience to report. An unusual experience is either surprisingly good or exceptionally bad. I won’t give any feedback for a transaction in which I paid the agreed amount of money, received the product in a reasonable time, and the product worked as expected.
Adding reviews outside of that policy has two negative effects: it adds useless noise to the review section, and it tends to inflate star-system grades.

The HP Envy 13z is a lightweight, reasonably high-performance laptop with a relatively low price tag - under $600 for the 1080P 13" touchscreen, flip-hinge to tablet, backlit keyboard, 8GB RAM, 250GB SSD, Ryzen 2300U four-core system weighing a little over two pounds.
(Those were the specs.)
It generally compares favorably …

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.
