  • If you know your VPN’s DNS server, you can change your local DNS so that it redirects your specified domains/subdomains to the appropriate, local IP address and all other requests would then use your VPN’s DNS.

    If you don’t know your VPN provider’s DNS server information, you may be able to still do something similar to the above depending on your setup. Otherwise, you could run your own DNS resolver or use a different DNS provider. I guess doing so could potentially be used to further fingerprint you, but the concern about “DNS fingerprinting” is moreso DNS leaks where your DNS queries are accessible to unintended parties due to improper configuration.

    I believe the only other option would be to change your hosts file on each device you want to use to connect to your services, which is probably not the best approach and may be challenging/impossible for certain devices.

    Also, unless you setup the self signed certs to be trusted on a network/domain level (or again on each individual device), you will likely get a warning/error about the self signed certs when accessing your services. You may need to work through this process each time the certs renew.

    I recommend buying a domain if you do not already have one and finding a service that provides wildcard certification challenges. This would allow you to setup a valid, trusted certificate that you could reuse for all of your services. The only thing that you would need to provide is an email address (can be any email address) and your domain name (in addition to other information that may be required to setup an account at the cert provider, but you may already have an account there as it could be the domain name registrar or other services like VPS providers, Cloudflare, etc.). Since it is a wildcard cert, each subdomain does not need to be set publicly and if you only use the domain within your network, the domain does not need to be publicly associated with any IP address.

    If you do go forward with that approach, you could use the wildcard cert directly within NginxProxyManager or other reverse proxies. They will also automatically update/maintain the cert for you.


  • There is no one-size-fits-all solution and there likely isn’t a solution that works for everyone even in specific situations due to different threat models. Purchasing and using a custom domain is often listed as a good practice for maintaining a person’s privacy. However, it can be even more detrimental to a person’s privacy than just using a trusted email masking/forwarding service and trusted email provider. For example:

    • The domain is purchased without WHOIS protection (or without using non-personal information) or the WHOIS protection is not renewed
    • The email server is hosted on hardware that can be linked to other services that identify the individual (eg: the email is self hosted using a home IP address)
    • A self hosted email server is configured in a way that leaks information or is configured insecurely
    • The email domain is used by only one person, which enables agencies to link each individual, unique email address back to that individual and create an aggregated profile across various accounts/services
    • If the domain/DNS is not configured properly (or if the domain is not renewed), then the domain (and thus the email accounts) can be hijacked, which could lead to any additional accounts/services that are still using the domain vulnerable to a take over attack
    • The email server is hosted by a privacy invasive company/service
    • The person assumes that all emails are private since they use a custom domain on a trusted email provider (or self hosted email server), but continue to send emails containing sensitive information to email accounts running privacy invasive email services (eg: Gmail)

    Please note that I am not saying that this is not a good option, but I just wanted to note some of the things that should be considered if a person decides to use a custom email domain to improve their digital privacy.



  • My beef with them is that they’re either pushed by scammer to empty honest but gullible people’s bank accounts, or they’re used to pay for illegal activities because they’re totally opaque and unregulated.

    Scammers also use gift cards, checks, wires, cash, bank accounts, investment funds, and many other means to accomplish this. Several of them are tightly regulated and it does not seem to deter or prevent the scams from occurring.

    My other beef is that they’re really securities and they’re not subject to the rules on securities for a reason that totally escapes me.

    Admittedly, I am not well versed in this area. Do you foresee a way to properly subject cryptocurrencies to the same/similar regulations as other securities while still providing many/all of cryptocurrencies’ benefits, including anonymity? Are the legitimate cryptocurrency exchanges (eg: Coinbase) not subject to those regulations? How different is this from individuals being taxed on gains/losses from cryptocurrencies?

    I don’t do cryptocurrencies both out of self-financial preservation, and also because I refuse to participate - and thus promote - stuff that’s generally bad for society as a whole.

    The first part is in relation to investing in cryptocurrency moreso than using cryptocurrency.

    What makes cryptocurrency generally bad for society as a whole? While I am not familiar enough with the current estimates, I know there are environmental concerns (eg: water/electricity usage, required hardware, etc.). I concede that the environmental impacts may be (and likely are) worse than traditional fist currencies, I am unaware of other reasons that make cryptocurrency generally bad for society as a whole.

    Trump loves em

    Many privacy advocates also love cryptocurrency. Two different people or groups of people (no matter how similar or different) can have one or more shared interests, even if the reasons or motivations are drastically different. It is likely best to avoid politics on this topic.


  • Cryptocurrency

    Hard no. I don’t partake in scams, even for the sake of privacy.

    Is this in relation to the monetary value of cryptocurrency or the anonymity of cryptocurrency?

    The list included cryptocurrency as a channel for anonymous payments, not an investment opportunity. The two cryptocurrencies listed are two of the more well established cryptocurrencies that are more widely accepted than many other cryptocurrencies (granted, one or both of them are still not accepted by a large number of merchants). Additionally, the list also mentions some of the considerations necessary to help ensure the cryptocurrency is obtained anonymously.

    If the list only included insert_newly_created_obscure_cryptocurrencies then this would definitely be more concerning.

    However, if the cryptocurrency is both obtained and used “properly” where the person is ultimately anonymously exchanging cryptocurrency for a desired good(s) or service(s), is it truly a scam?


  • That’s true, but how often have you heard a finance team member wanting a CSV file so they can more easily process the data using Pandas or visualize it with MatPlotLib? How many accountants or finance people (especially those that ask for everything in Excel) do you know that is comfortable writing even a single line of Python code? How many of the finance team’s Excel-based tools will Python integrate well with? What feature(s) does Python within Excel provide that Excel (formulas, pivot tables, VBA, Power Query, Power Pivot, etc.) does not provide that someone on the finance team would need? What advanced charting/dashboarding functionality does Python in Excel provide that isn’t better accomplished in PowerBI (if not handled by standard Excel charts/graphs)?

    Don’t get me wrong - Microsoft’s implementation of Python in Excel has its merits and will solve some problems that otherwise would not be possible in Excel and will make some people happy. However, this is not the solution most people were expecting, asking for, or find useful.


  • I agree with everything you said, but (in Microsoft’s eyes) this is a feature - not a bug.

    Without this cloud component, how could:

    • Microsoft make sure that the accounting team does not introduce a malicious/old Python library into the Excel file?
    • Microsoft protect its users from writing/running inefficient, buggy, or malicious Python code?
    • Microsoft provide a Python runtime to users who do not know how to install Python?
    • Microsoft charge to run code that you wrote in a free, open source software programming language on a device that you own?

  • Over a year later and I still do not understand what the use case for this is.

    A lot of the examples/documentation that was made by Microsoft for this seems to focus on data analysis and data visualization. Anyone in those fields would probably prefer to get the data out of Excel and into their tool/pipeline of choice instead of running their Python code in Excel. That also makes the big assumption that the data being used is fully contained within the Excel file and that the libraries used within the code are avalaible in Excel (including the library version).

    For anyone looking to learn/use Excel better, I doubt the best use of their time is learning a new programming language and how Excel implements that programming language. They would likely be better off learning Excel’s formulas, pivot tables, charts, etc. They could even learn Power Query to take things to another level.

    For anyone looking to learn Python, this is absolutely a terrible way to do so. For example, it abstracts away library maintenance, could provide modified error messages, and makes the developer feedback loop more complicated.

    If you want to automate Excel then this realistically allows for very little new functionality that did not exist prior to this feature. Using other Python libraries like OpenPyxl and xlWings will still be required to automate Excel.

    I am sure there are edge cases where this iteration of Python in Excel is perfect. However, this feels like a checkbox filler (“yeah, Excel supports Python now”) than an implementation of an actual useful feature. A fully featured and supported Python library that manipulates Excel/Excel files would have been a much more exciting and useful feature - even if it had to be executed outside of Excel, like OpenPyxl.


  • This is awesome! I wonder how it will compare to the competition when it’s generally available.

    Does anyone have any information about the other offerings mentioned in the blog post?

    In the future, we intend for Appointment to be part of a wider suite of helpful products enhancing the core Thunderbird experience. Our ambition is to provide you with not only a first-rate email application but a hub of productivity tools to make your days more efficient and stress-free.





  • Just to clarify - this is just an update that (I believe) is only available on IzzyOnDroid’s F-Droid Repo, which previously had prior Findroid versions available. This new v0.15.0 is not available on the main F-Droid Repo.

    Is anyone only able to download the 32-bit version of this app via F-Droid? It looks like a 64-bit version has been made available starting with v0.3.0 and is also available on this new version.



  • I’m curious about this. The source text of your comment appears that your comment was just the URL with no markdown. For your comment about a markdown parsing bug to be true, shouldn’t the URL have been written in markdown with []() notation (or a space between the URL and the period) since a period is a valid URL character? For example, instead of typing https://google.github.io/styleguide/cppguide.html., should [https://google.github.io/styleguide/cppguide.html.](https://google.github.io/styleguide/cppguide.html) have been typed?


  • Yes, I am using PersistentVolumes. I have played around with different tools that have backup/snapshot abilities, but I haven’t seen a way to integrate that functionality with a CD tool. I’m sure if I spent enough time working through things, I may be able to put together something that allows the CD tool to take a snapshot. However, I think that having it handle rollbacks would be a bit too much for me to handle without assistance.


  • Thanks for the reply! I am currently looking to do this for a Kubernetes cluster running various services to more reliably (and frequently) perform upgrades with automated rollbacks when necessary. At some point in the future, it may include services I am developing, but at the moment that is not the intended use case.

    I am not currently familiar enough with the CI/CD pipeline (currently Renovatebot and ArgoCD) to reliably accomplish automated rollbacks, but I believe I can get everything working with the exception of rolling back a data backup (especially for upgrades that contain backwards incompatible database changes). In terms of storage, I am open to using various selfhosted services/platforms even if it means drastically changing the setup (eg - moving from TrueNAS to Longhorn, moving from Ceph to Proxmox, etc.) if it means I can accomplish this without a noticeable performance degradation to any of the services.

    I understand that it can be challenging (or maybe impossible) to reliably generate backups while the services are running. I also understand that the best way to do this for databases would be to stop the service and perform a database dump. However, I’m not too concerned with losing <10 seconds of data (or however long the backup jobs take) if the backups can be performed in a way that does not result in corrupted data. Realistically, the most common use cases for the rollbacks would be invalid Kubernetes resources/application configuration as a result of the upgrade or the removal/change of a feature that I depend on.





  • Everything I mentioned works for LAN services as long as you have a domain name. You shouldn’t even need to point the domain name to any IP addresses to get it working. As long as you use a domain registrar that respects your privacy appropriately, you should be able to set things up with a good amount of privacy.

    Yes, you can do wildcard certificates through Let’s Encrypt. If you use one of the reverse proxies I mentioned, the reverse proxy will create the wildcard certificates and maintain them for you. However, you will likely need to use a DNS challenge. Doing so isn’t necessarily difficult. You will likely need to generate an API key or something similar at the domain registrar or DNS service you’re using. The process will likely vary depending on what DNS service/company you are using.


  • Congrats on getting everything working - it looks great!

    One piece of (unprovoked, potentially unwanted) advice is to setup SSL. I know you’re running your services behind Wireguard so there isn’t too much of a security concern running your services on HTTP. However, as the number of your services or users (family, friends, etc.) increases, you’re more likely to run into issues with services not running on HTTPS.

    The creation and renewal of SSL certificates can be done for free (assuming you have a domain name already) and automatically with certain reverse proxy services like NGINXProxyManager or Traefik, which can both be run in Docker. If you set everything up with a wildcard certificate via DNS challenge, you can still keep the services you run hidden from people scanning DNS records on your domain (ie people won’t know that an SSL certificate was issued for immich.your.domain). How you set up the DNS challenge will vary by the DNS provider and reverse proxy service, but the only additional thing that you will likely need to set up a wildcard challenge, regardless of which services you use, is an email address (again, assuming you have a domain name).
