Comment Resource Hub to Defeat the DataTheft Enterprise (Score 1) 81

Nearly every new electronic device is infested with data collection -- DataTheft -- that users neither want nor need. Corporations want us to give up trying to protect our privacy, but to defeat this unwelcome personal invasion we need a resource hub to help us find, identify, and disable or destroy components and firmware responsible for the theft. Should this Resource Hub be formed and funded as:
(a) Political lobbying group funded by contributions
(b) Repository and wiki for detecting and disabling DataTheft in devices, vehicles, etc., funded by contributions and sale of kits and tools if required
(c) Essentially a near clone of iFixit, funded by contributions, kit and tool sales, and bounties for specific research and methods
(d) Clandestine funding of Cowboy Neal's DataTheft Jammer to create a personal privacy field

(1) Never
(2) Would pay more for a model with 'smart' disabling capability
(3) Would accept lesser performance and/or features for non-'smart' model

Liquid Platinum At Room Temperature: The 'Cool' Catalyst For a Sustainable Revolution In Industrial Chemistry (phys.org) 20

An anonymous reader quotes a report from Phys.Org: Researchers in Australia have been able to use trace amounts of liquid platinum to create cheap and highly efficient chemical reactions at low temperatures, opening a pathway to dramatic emissions reductions in crucial industries. When combined with liquid gallium, the amounts of platinum required are small enough to significantly extend the earth's reserves of this valuable metal, while potentially offering more sustainable solutions for CO2 reduction, ammonia synthesis in fertilizer production, and green fuel cell creation, together with many other possible applications in chemical industries. These findings, which focus on platinum, are just a drop in the liquid metal ocean when it comes to the potential of these catalysis systems. By expanding on this method, there could be more than 1,000 possible combinations of elements for over 1,000 different reactions.

Platinum is very effective as a catalyst (the trigger for chemical reactions) but is not widely used at industrial scale because it's expensive. Most catalysis systems involving platinum also have high ongoing energy costs to operate. Normally, the melting point for platinum is 1,700C. And when it's used in a solid state for industrial purposes, there needs to be around 10% platinum in a carbon-based catalytic system. It's not an affordable ratio when trying to manufacture components and products for commercial sale. That could be set to change in the future, though, after scientists at UNSW Sydney and RMIT University found a way to use tiny amounts of platinum to create powerful reactions, and without expensive energy costs.

The team, including members of the ARC Center of Excellence in Exciton Science and the ARC Center of Excellence in Future Low Energy Technologies, combined the platinum with liquid gallium, which has a melting point of just 29.8C -- that's room temperature on a hot day. When combined with gallium, the platinum becomes soluble. In other words, it melts, and without firing up a hugely powerful industrial furnace. For this mechanism, processing at an elevated temperature is only required at the initial stage, when platinum is dissolved in gallium to create the catalysis system. And even then, it's only around 300C for an hour or two, nowhere near the continuous high temperatures often required in industrial-scale chemical engineering.
The results have been published in the journal Nature Chemistry.

I am using Neeva Search + Protect for Firefox on Fedora Linux 35 with Decentraleyes, DuckDuckGo Privacy Essentials, Canvas Defender, Privacy Badger, Privacy Possum, NoScript, uBlock Origin, and Cookie AutoDelete extensions. I like Neeva Search very much, particularly in that when you click on a result you want to explore, it opens in a new tab instead of replacing the one you're on. I use about nine different computers from the same ISP IP and one using a VPN. For some reason Neeva Search seems to be limited to about four (?) systems and I don't know the reason for that but I imagine it relates to monetization. The results are generally very good and I seldom find anything on DDG that isn't shown in Neeva. I do use Google -- reluctantly, as they have removed the 'Don't' from their former motto of 'Don't Do Evil' -- but for image search I still find Google better. I have noticed that Google has become the next thing to irrelevant for things like electronics part number searches, for reasons others have eloquently described here. An education I did not want and certainly did not anticipate has made me seat-of-the-pants agile with NoScript et al, to see just what tricks I need to adapt to this week, e.g. for my favorite mainstream news sites. While I am not a terr'rist or any threat to anyone, I vehemently object to the entire DataTheft Enterprise on principle and, as a person at least peripherally involved in pre-WWW Internet, am profoundly sad that it has turned out to be everything we didn't want.

Comment CorpGov Despises Cash (Score 5, Insightful) 660

CorpGov wants to track everyone. Everywhere. Always. Cash is difficult to monitor. With your Personal Tracking Device in your pocket, and your identify-linking electronic purchases absolutely tagged to you and you alone, CorpGov feasts. They get to do whatever they want with everything you do that they can track, and what is more definitive and commercially valuable than what you buy? And where? And when? So of course CorpGov is doing everything it can to sow the seeds of doubt about the safety of carrying cash, which they cannot so easily track. As if they held your interests in mind at all, let alone paramount. 'Cash Is Dangerous' is true to the degree that you are Sheeple.

Kobo rarely even gets mentioned in ereader discussions, but it is better than any other device on the market for myriad reasons, chief among which are that: (1) it reads just about every format ebooks have ever used; (2) It is arguably more easily independent of any vendor lock-in, walled-garden BS than any other ereader; and (3) it *functions* better than most ereaders in the first place.

Combined with Calibre, nothing can touch it. I have the Kobo Aura H2O with well over 1000 hours use and that device has definitely qualified among the 'cold dead fingers' realm of my possessions. Note that I avoid all non-locally-controllable anything like the plague, especially including walled-garden, proprietary-diseased clouds and their ilk, where I am supposed to trust some third party -- who holds my wellbeing in the lowest possible regard -- to act in my best interests. No thank you. The Kobo line is as close to Open Hardware ereaders as we are likely to see in the near future.

Comment Re:Logitech K800 (Score 1) 452

I concur, the Logitech K800 has been a delightful surprise throughout the more than three years I have owned it. Though I am not a gamer, I used to be a typesetter and routinely cruised at 120 wpm on multi-thousand-dollar typesetting machines with superb and rugged keyboards (I can't type that fast anymore; it takes more practice). Consequently I am ruthlessly picky about keyboards, and while the K800 does not resemble those typesetter ones, it does offer stroke and action better than any *computer* keyboard I have ever used, including the IBM Model M. The keyboard is silent, the battery lasts for weeks even when left constantly powered on, the backlight is far more useful and responsive than I had imagined, and so far there is no noticeable wear on keys or their markings, apart from the spacebar having a shiny place where my thumb hits it. Cleaning is easy; switch it off, wipe it down, switch it back on. Very highly recommended.

Comment Get A Silent Elegant Case (Score 3, Informative) 720

I build home systems sometimes for clients, and the Wife Factor is frequently the most critical aspect. This has been true since I started in 1985, but is more true now as computers have become essential to so many households.

In my experience, the Fractal Design cases (e.g, the Define R4) have two wife-pleasing qualities:
(1) They are simple, elegant, unadorned museum quality sculpture-like mini-monoliths; and
(2) They are literally almost completely silent. I don't mean merely quiet, I mean you cannot tell whether the system is on or off. This is with fans, not water cooling.

Understand that this may not solve your real problem, which may be the mere presence of the machine in the living room. What it will do is force an honest exposure of the real issue, and besides that you'll still have a great case you can migrate components into and out of for years and years. Also it means you don't need a new rig, just new clothes for for the rig you already have.

Note that I do not have any relationship with that company aside from buying their cases for some system builds where they fit best. I will say that they are superbly designed inside, and the designers obviously build systems themselves. You'll know what I mean if you get one.
