  • 99% isopropyl alcohol is ideal as a solvent or cleaning agent for industries that produce water sensitive items, therefore rapid evaporation and low water content is favorable. 99% USP IPA provides the lowest presence of water and in some forms is free from denaturants. Computer technicians, medical device manufacturers, printed circuit board manufacturers, and soldering and rework technicians prefer immediate evaporation for work with sensitive devices such as integrated circuit adapters, computer chips, and circuit boards. 99% IPA evaporates cleanly and minimizes residual substances. Rapid evaporation reduces shelf life but is more effective against sticky residues, grease, and grime than 70% concentrations. Because isopropanol is hygroscopic, acetone may yield better grime fighting results for inks or oils.

    The URL you shared recommends using 99% IPA for electronics.


  • The individual who readily labels others pedophiles merely for wanting to rescue kids (see Unsworth) yet creates tools lacking any reasonable safeguards against child abuse material (measures that should have been relatively simple to implement) does not meet my definition of success. Likewise, a person who fails to meet his own deadlines is not successful even from some capitalistic perspectives. Someone who constantly seeks validation is not considered successful by most standards. All in all, Musk is an unsuccessful pedo guy.





  • I assume that trolls try to provoke erratic and disproportionate reactions from others, becoming a part of their own miniature sitcom for their own entertainment. It could be because of a sense of victory upon watching others break down (assuming a zero sum point of view). It could be the viewpoint that trolls are at their own higher level compared to others and understand each other while making fun of the lower levels (a false sense of superiority). Maybe it’s a [case of] holding onto their own beliefs and assuming that they needn’t change themselves if they disrupt all conversations that may cause harm to their own beliefs. It might be attention seeking or an escape mechanism. It could also be a desire to avoid fitting in with everyone else and remaining separate.

    (edit: grammar)


  • There are some generic observations you can use to identify whether a story was AI generated or written by a human. However, there are no definitive criteria for identifying AI generated text except for text directed at the LLM user such as “certainly, here is a story that fits your criteria,” or “as a large language model, I cannot…”

    There are some signs that can be used to identify AI generated text though they might not always be accurate. For instance, the observation that AI tends to be superficial. It often puts undue emphasis on emotions that most humans would not focus on. It tends to be somewhat more ambiguous and abstract compared to humans.

    A large language model often uses poetic language instead of factual (e.g., saying that something insignificant has “profound beauty”). It tends to focus too much on the overarching themes in the background even when not required (e.g., “this highlights the significance of xyz in revolutionizing the field of …”).

    There are some grammatical traits that can be used to identify AI but they are even more ambiguous than judging the quality of the content, especially because someone might not be a native English speaker or they might be a native speaker whose natural grammar sounds like AI.

    The only good methods of judging whether text was AI generated are judging the quality of the content (which one should do regardless of whether they want to use content quality to identify AI generated text) and looking for text directed at the AI user.



  • It’s most likely an error with the nozzle height. The PEI plate not heating up enough shouldn’t cause the adhesion in the photo above (and this is not a first layer problem, as the error is not at a uniform height). Additionally, a few lines are very faintly visible on the plate where they shouldn’t be, indicating nozzle height. Make sure that it is easy to move a piece of paper between the nozzle and the PEI plate when adjusting the height, feeling only a very small amount of pressure as you do so.



  • Not all hierarchies are bad. For instance, in a judicial system, there need to be different tiers of courts as otherwise, if courts had universal authority and made conflicting decisions, it would complicate the law more so than it is already.

    Similarly, in a large society that needs unity, if people make all decisions, the results would be catastrophic as most people don’t have the time or energy to focus on every mundane decision. In such a case, elected representatives becomes mandatory, creating a hierarchy.

    Yet another example is cases where fast decision-making is required (e.g., to respond to an emergency). In such a case, there needs to be a central authority who holds others responsible and coordinates response.

    Ultimately, if you consider a hierarchy where accountability is possible i.e. one party may have more power over the second than the second over first but the second still has some power over the first, then it makes accountability possible in hierarchies. Hierarchies are only wrong when the power gap increases, a small power gap is alright provided it doesn’t widen with time.

    You could make the argument that a chain of accountability is better (X->Y->Z->X), but even such chains may include hierarchies (i.e. X itself is a hierarchy). Similarly, authority diffused among different people also suffers from potential shifting of blame. Truly neutral relations between different parties are impossible and ultimately, a power difference exists between any two parties, though it may be minute, and this power gap must be acknowledged.

    In conclusion, there are a lot of disadvantages of hierarchies but there are some domains where hierarchies are good. There is no system of distribution of power that is without flaws.


  • Enable Administrator password on the menu screen, create a persistent storage (if it doesn’t already exist), download the Flatpak file from the website, and run

    torify flatpak install /path/to/file
    flatpak run io.github.softfever.OrcaSlicer
    

    Using an AppImage is not a good idea because they have a tendency to give errors if proper software and version are not installed on Tails (on my Tails USB, this was because of GCC) unless you compile your own AppImage. Using Flatpak is better as it allows you to run software on your system even if the versions of GCC etc. are not up to date.

    Please keep in mind that I have not confirmed whether this method is secure and would advise that you consider whether this is secure or not depending on your threat model.


  • TL;DR: not possible with random cookies, too much work for too little gain with already-verified cookies

    There is no such add-on because random cookies will not work. Whenever someone has been authenticated, Google decides the cookie the browser should send out with any subsequent requests. Google can either choose to assign and store a session id on the browser and store data on servers or choose to store the client browser fingerprint and other data in a single cookie and sign this data.

    Additionally, even with a verified session, if you change your browser fingerprint, it may trigger a CAPTCHA, despite using a verified cookie. In the case of a session token, this will occur because of the server storing the fingerprint associated with the previous request. On the other hand, if using a stateless method, the fingerprint will not match the signed data stored inside the cookie.

    However, this could work with authenticated cookies wherein users contribute their cookies to a database and the database further distributes these cookies based on Proof of Work. This approach, too, has numerous flaws. For instance, this would require trusting the database, this is a very over engineered solution, Google doesn’t mind asking verified users to verify again making this pointless, it would be more efficient to simply hire a team of people or use automated systems to solve CAPTCHAS, this approach also leaks a lot of data depending on your threat model, etc.




  • The DKTB is a personal app. It is therefore assumed, that the User will not share it with other people, and that only the User can access and control their personal DKTB. Ultimately, this means that all attestations in a DKTB are expected to pertain to and only be presented by the same User. This is enforced by requiring the user to authenticate using biometry or PIN-code when using the app and only allowing the DKTB application to be installed on one device per user. (from the PDF)

    This is a false assumption: PIN codes can be bypassed by sharing them with others. Devices can be faked unless using hardware attestation, which prohibits any modifications to the device which may be undertaken by those interested in rooting or installing a custom OS.

    Users can initially acquire a DKTB on their smartphone or tablet via Google Play or the Apple App store. (from the PDF)

    This method requires the use of a vanilla, unmodified device, effectively prohibiting modifications to devices that one might wish to alter.
