  • Even if the algorithm will perform better on CPUs than other crypto algorithms, there’s still the fact that the processor in a GPU is much less complex and so: many more tasks can run in parallel because they’re all very similar, the bus is much shorter, bandwidth to memory is much higher, and memory is generally much higher performing. So overall, mining on a GPU will generally be more energy efficient than on a CPU. And of course crypto becomes harder and harder to mine as they grow, by design.



  • Not sure that’s true. And mining on a CPU is even less efficient. Your hash rate will be way lower unless you’ve got a really high-end system with a really low latency bus and RAM. And if your hashrate is too low, it would take months for you to find a single block unless you’re pooling with a bunch of others and splitting the profit. It’s quite variable, but very, very few people can make profit on any popular coins. Too many people to compete with to find a block.

    Oh and don’t forget cooling cost. The fans in the computer, the fans in your house, and your air conditioner in your house need to disipate the heat and there’s a lot more generated per clock cycle from a CPU than a GPU using comperably old technologies. If you live somewhere that you’re producing more electricity with solar than you consume, then it’s probably not a cold climate.



  • That makes them think you aren’t available, but if you have any kind of voicemail it means they know it’s a real number so autodialers will probably still try later. I think this request is how can we fool the spammers (automated or otherwise) to think the number is totally invalid so they stop calling it.

    That is difficult since there’s probably some indication from the phone company other than just a voice message that indicates a number is invalid/unallocated.

    That said, muting is the way I do it, but now most autodialer systems are configured to call twice in a row to get around the Do No Disturb settings on most cell phones, so it is more annoying now.

    You still have an upstream DNS server that you rely on to provide updates to your unbound server. Problem is that corporate or extremist government controlled DNS servers can track all of your requests as well as censor any domains they don’t approve of. And if DNS servers or their users don’t use secure protocols, then those requests additionally are tracked by ISPs or any other systems the requests travel through as well as them having the ability to block individual requests they don’t want fulfilled like the Great Firewall does or most corporate internal systems sometimes do to prevent employees from accessing social media or other sites they deem not work related.




  • Problem with Manjaro is they have their own opinionated repository that is not always in sync with Arch because they try to introduce more “stability”. I found this actually caused the opposite in most cases as there are a lot of dependencies that end up being behind and so you can’t install more stable versions of a lot of software. With the complexity of modern software dependencies, it has become a big problem. Also, they have in the past caused lots of problems with AUR and have let their SSL certs expire multiple times. Overall, they just haven’t been reliable IMHO, so I moved to Fedora a while back.



  • Real problem is that the rules change every year so the software has to be constantly updated and that sometimes requires insider information about what changes are coming. Often the IRS publications aren’t available until the last minute or later, definitely not in enough time for proper quality processes. So, while simple returns can sometimes be done with software like this, a lot of people rely on the software or agencies to know all the new rules.

    That being said, I would like it a lot if there was a way to file very single form, but fill it out manually in the software, without calculations being done by the software. At least then you could file electronically regardless of what complex forms you need to file with complex worksheets and sub-forms, if the software didn’t need to know about those things, just the forms you actually file. As it is, the only way to file these is with expensive software or on paper which can take many months for the IRS to process and you could be on the hook for interest if you file something wrong and the IRS doesn’t reject in time for you to correct it and resubmit before interest charges accrue.

    Also, a lot of IRS processes require the software to be certified (or at least did the last time I looked at it) because their software isn’t sophisticated enough to validate the complex forms, so getting that certification might be difficult for FOSS software. I’ll be interested to see how that plays out.


  • If you want to be as secure and private as possible, your best option is to set up your own build servers and automate builds, and validate the components used by each product conform to your needs and standards for security and privacy, and deployment to your own repository that your devices use for updates.

    Beyond that, there are tradeoffs based on your needs with each app store out there. If you need total privacy on what you install and your devices are already not connected to the internet, then a VPN or Tor to obfuscate your identity might be all you need. If you’re more concerned about components of applications that contain spyware, then some stores like fdroid has a lot of data available to hep you decide if the app is OK for your needs, otherwise you’d need to build your own packages or verify them manually before installation. And there are various other tradeoffs between more accessibility vs. more security and/or privacy.


  • Can’t do that with email. Email doesn’t have the necessary protocols to keep a file from being copied, scrub file systems, or maintain external links to trusted time keeping sources or control over the hardware to prevent screenshots or other methods to save the data as it’s being displayed to the user.

    There are some possible partial implementations like encrypting a file and only allowing decryption and display on a remote server. But then what’s the point of making it an email in the first place? And if the method for viewing the data is something like a website, that doesn’t prevent screenshots or other ways of storing the data.

    The only way to truly have self-destructing content of any kind is to use a device that’s fully controlled, a sever that makes sure the device is not compromised, and a neutral third party you trust to keep all recipients from tampering with the server and devices. Otherwise, if one of the users gets control of any component, they will be able to compromise the system. Unfortunately, there are no trustworthy companies who aren’t under pressure to profit fr your data or from governments to allow access to your data. So there can never be a commercial product like that. And email doesn’t have any of this as it’s designed to be portable, not controllable.
