Desktop Turing-Welchman Bombe Build 69

An anonymous reader writes: I completed a months long project to build my own version of the Turing-Welchman Bombe. My machine uses a Raspberry Pi2 and an Arduino to drive stepper motors to turn the three output indicator drums and to drive an LCD display, to work like the indicator unit on the real Bombe. Everything was custom made by me at home. The unit is built to reflect the style of the real Bombe at Bletchley Park and to run in a similar way but as a portable, desktop sized unit. To demonstrate it I use the same Weather Report Menu as used at BP to demonstrate their real Bombe. The entire build was painstakingly documented over many months but the link given shows an overview and a film of the completed machine in action.

With paper, the tree is crushed. Why would you need a large straight tree for that? Economics re-enforces this. You're not going to pay extra for a large tree just to crush it

What? Have you even been to an active paper company forest?

Yup! My cousins used to cut trees for the paper mills.

It wouldn't make any sense to take a nice large, straight tree and turn it into paper of any sort. If you need a roof or wall, you have to start with a large straight tree.

It amazes me that people think they are saving a tree when they don't use paper. I highly doubt they have even seen what kind of trees paper is made from. When I explain this, people usually tell me, "That makes sense." Of course it does!

This reminds me of the Mike Rowe's TED talk about how a lot of people talk about things they think they know. Until a person actually tries sheep farming, they really don't know a thing. I ask my dad (grew up on a farm) about the subject Mike Rowe covered in his talk, and sure enough, he knew about it.

Also of note, the abstract mentions that the number of trees has been too low in previous estimates. I wonder how this new estimate will change climate/CO2 modeling:

"This map reveals that the global number of trees is approximately 3.04 trillion, an order of magnitude higher than the previous estimate."

What Microsoft turned WBEM into is a monstrosity. WBEM was just supposed to be an enhancement of SNMP. Instead of key/value type system, it allows real parameters to be sent to the remote system. But then, Microsoft. And now Microsoft is abusing it even more with DSC! WBEM was never intended to do some link DSC. What RedHat is doing with WBEM is exactly what it is supposed to be used for.

RHEL has a solution for this now. It is called Software Collections and the Developer Toolset. A developer can use latest Python, but the base system still uses the "stable" packages. All of this is still packaged as rpms, so the same management tools still apply. Note that the support cycle is much shorter for packages in the Software collections, but it is easy enough to take upstream and use the .spec file to roll your own.

Which projects are 'not invented here' by RedHat? I suppose you could argue that buying iPlanet/Sun LDAP server is a rejection of OpenLDAP, but at the same time, they were trying to build something much more comprehensive. The fruits of that purchase is FreeIPA. FreeIPA is awesome.

They are also trying to introduce a proper management layer using WBEM. But it doesn't stop at just installing an OSS WBEM server. They are building out an entire management interface which in turn requires them to write more providers. Not invented here? There isn't really anything out there, so they are making it themselves. All opensource.

So beyond RedHat contributing to a ton of existing projects, they are building things (hard things), not only to make a better distro, but things that help the entire Linux universe. But hey, Ubuntu is making Mir. So there is that.

Is Gnome 3 that controversial anymore? I thought Unity surpassed it in controversy.

I've been running RedHat/Fedora since 4.0.4, so as far as I can tell, RedHat has never left my desktop. One box has been updated for each release since RedHat 9. That included switching to x86_64 when I replaced the motherboard, but kept the HDD.

RHEL has good 3rd party support for when you need it. RedHat also spends a lot of work and money on compliance testing (e.g. Common Criteria and SCAP). This helps out with HIPAA and PCI regulation. It helps fill out that little check box so we all can get back to worrying about real security. I personally use RedHat's IdM (which is really FreeIPA). FreeIPA is awesome.

40% ain't bad for CentOS/RHEL. I'm a bit surprised that Debian, which Ubuntu is based on, has fallen so far.

Ubuntu is a fine distro, I just don't like the company and the leadership. RHEL is a fine distro, but it purposely has a slower update cadence. I love the RedHat company and how committed they are to OSS. Everything they buy (and they've spent a lot on acquisitions over the years), they open source.
