If two or more people don't want that link up, I can just take it down. It would be up on >>>/os/ since the person running /os/ is also hosting it for someone that goes to both /os/ and /tech/. It's not a true collective effort to say the least, it's just one guy who's curating the links and picked some ideas from a thread that he made on /tech/ so that he could make the claim that it was a collaboration, which if you treat him and the Endwall guy as /tech/ users, then sure, why not. It is not however, the "official end/tech/'s secure computing practices links". If you've got a better list, I might consider putting that up as well if it isn't half assed.

>All those exculsions
He needs to trim the exculsions way down and explain why each country is chosen. Ohterwise he is making people more insecure using that exclusion list rather than more secure.

If he doesn't understand what he is doing here (simple copy/paste from some random anon) he should remove that information entirely.

>>12721
The link is fine and he does have a disclaimer at the bottom, but that Tor exclusion list needs a heavy revision or be removed.

CPU, RAM, GPU: 1x single board computer

A Single Board Computer provides every component needed to build laptop, except for battery, display, keyboard and case, each of which can be added separately.

Single Board Computers provide CPU, RAM, GPU, motherboard and some other integrated features on a single board. They are full desktop computer system that is sufficiently small and low power consuming to be used as a mobile, DIY laptop. They are also very low cost (<$50).

The most important feature of Single Board Computers is that there are models that are fully open source. It is possible to build a fully functional laptop with Free Software only, including free firmware, wireless and 3D video acceleration drivers. It is even possible to get SBCs with open source hardware designs.

For reference:

Single Board Computers with free 3D video acceleration (Etnaviv)
Nitrogen6X ($225): Quad core ARM A9 @ 1 Ghz, Freescale i.MX6, Vivante GC2000, 2 GB DDR3, best option, compatible with mainline kernels
Nitrogen6_MAX ($299): Quad core ARM A9 @ 1 Ghz, Freescale i.MX6, Vivante GC3000, 4 GB DDR3, faster Nitrogen6X
Wandboard QuadPLUS ($139): Quad core ARM A9 @ 1 Ghz, Freescale i.MX6, Vivante GC3000, 2 GB DDR3, cheaper version of Nitrogen6_MAX, not mainline

Open source hardware Single Board Computers
BeagleBone Black ($55): Single core ARM A8 @ 1 GHz, TI Sitara AM335x, PowerVR SGX530, 512 MB DDR3, fully open source except GPU, mainline compatible, https://github.com/beagleboard/beaglebone-black

Charger

The DIY Modular Open Source Laptop is designed to be charged by any combination of solar panel, handcrank generator, USB AC adapter, USB car charger, USB port or thermoelectric generator. Unlike most rechargeable electronics, each charger can charge the USB powerbank battery of the DIY laptop seperately from the DIY laptop. This flexible and modular charging ensures the DIY laptop never runs out of energy, yet never needs to be charged either.

For reference
USB solar charger: SOKOO 22W 5V 2-Port USB Portable Foldable Solar Charger ($55)
Handcrank generator: K-TOR Pocket Socket Hand Crank Generator Portable Power Supply 10 Watts 120 Volts ($60)
Pedal generator: K-tor Power Box 20 Watt Pedal Generator ($200)
Thermoelectric generator: Camping Stove Thermoelectric Generator TEG Power - Devil Watt 15 Watt ($304)

Each reference charger can provide the 5V 2A needed to charge a USB powerbank at full speed. The most convenient charger will depend on the situation.

Solar panels can provide >150 W unattended outdoors at daytime.
Handcrank or pedal generators can provide <150 W attended indoors or outdoors, day or night. Handcrank generators can be used while standing or moving, but pedal generators can be used while also using the DIY laptop.
Thermoelectric generators can provide >150 W unattended outdoors, day or night. Indoors with ventilation.
USB AC adapters can be used wherever there is AC electric grid.
USB car adapters can be used with most DC electricity sources such as 12 V car batteries or six 1.5 V AA batteries in series. USB car adapters can also convert DC from solar panels, thermoelectric generators, handcrank generators, DC wind or hydroelectric turbines into 5V DC for charging the DIY laptop.

Very nice. Really.
I think this could be minimized in size, though, using trackpoint ('clit') instead of touchpad and squeezing the components inside. The wood color would also call too much attention while using it in public, so a matte black painting would be nice.
I don't know if you're the creator, but this is pretty cool.

About the keyboard, I had this idea some time ago of using a foldable keyboard from Blackberry, like this one:
https://www.amazon.com/Stowaway-Ultra-Slim-Bluetooth-Blackberry-Handhelds/dp/B0002OKCXE

So, all the components would be together with the display, like a mobile 'tablet', and this foldable keyboard could be unfolded just when you start using the computer and would serve as the 'base' for the display. This could make it less havier and also would be smaller i size.

Never finished that project, but I still think it's a good idea (although I'm thinking about head-mounted displays with hand-adapted keyboard now, instead of conventional laptop format).

This is for those of you who ask about this form factor every so often. I hope enough people join so that he makes beige ones.

The X500 Pro is the final product in a line of computer cases designed a few years back (the X500 Plus and later the Evo with a mechanical keyboard) as a tribute to the computers of the '80s and '90s (Commodore, Atari, Sinclair etc...). It's a wedge styled computer case with built-in, full size mechanical keyboard.

The chassis that I originally opened this thread with is dead so I ended up finding a substitute in the Checkmate A1500 which has the pizza box form factor. It's for Amiga fans but can fit mITX/mATX with a full-size reference blower-style graphics card. There'll also be risers so you can slide your keyboard under it when not in use.

Palemoon blacklists NoScript Anonymous 05/12/2018 (Sat) 03:01:36 [Preview] No. 12708 [Reply] [Last 50 Posts]
As the subject says. It's been entered into their custom "bitch at the user with a popup until they disable it" database. To be fair to the developer, he has solid reasons for his stance. I'll try to summarize as there is a lot of misinformation and emotion out there fogging the issue.

1) The Palemoon project does not have enough developer juice to debug other software and addons.
2) Various users: "[website] does not work with Palemoon. Fix your shit, Moonman!"
3) Moonman: "Known issue. Stop being morons and disable NoScript. Thank you, and have a nice day."
4) Various users: "We did. Same problem. Fix your shit."
5) Moonman: "Oh. That's an actual issue with Palemoon then. I'm on it!"
6) Much hacking and cracking and time and talent are expended to no effect. Surprise! NoScript does not follow the standard of letting go of the browser when disabled. It lingers on. It has to be completely uninstalled with an added cache clearing operation on top of that.
7) Moonman: "It's NoScript. Get rid of it. Have a nice day."
8) Various users: "No. FIX YOUR SHIT!"
9) Moonman: "Crush. Kill. DESTROY!"

If you roll with my simplification you can see his point.

I have two observations. First, quite a few sites have a technical support checklist that runs like this: "What browser are you using? Palemoon? Oh good! We have two fixes you may choose from. One, use another browser. Two, go away and do not come back."

My irony sense is tingling.

More and more websites are using "loading" screens for some reason, and most of the elements are display:none until fully loaded and the js changes it. All this without any "javascript is required for this page to function properly" message. I think the currently popular UI kits (like bootstrap styles) are the one to blame here.

NoScript also has a very unintuitive pop-up interface:
>Allow http://endchan5doxvprs5.onion
>Forbid http://endchan5doxvprs5.onion
For the first time, it is not clear whether these are actions or statuses. Especially when you consider the icons next to them.

I can imagine how hard to troubleshoot this. But the way it is explained at http://blocklist.palemoon.org/info/?id=pm112 doesn't help anyone.

seamonkey just updated on my work computer (without asking I am flabbergasted) all of my add-ons still work though, which is surprising.
Only difference insofar as I can tell is it no longer just downloads stuff I tell it to download it asks where I want to download it each time which is a rather useless procedure.
It's still probably the best option for me at work on a windows computer.

I'm wrong about the use of encryption with the SSD. In fact, you can, but you can't trim the SSD.
So if you're doing heavy work, then it'll be a real problem. I'm not even talking about buying it second hand, and so getting an already used SSD. But you still can use it.

But we have to treat SSDs differently regarding sec.
