Deutschlands Migrationsdebatte ist außer Kontrolle: Was früher nur Rechtsextreme forderten, finden auch etablierte Mitte-Parteien heute völlig okay -- [Meinung]
  • Von denen, die 2015 als Geflüchtete herkamen, waren 2022 64 Prozent erwerbstätig.

    Na ja, ich bin überzeugter Sozialdemokrat und vermutlich die letzte Person, die man rechts nennen könnte. Aber ist 64% nicht ein wenig niedrig, vor allem unter der Annahme, dass die meisten Geflüchteten recht jung waren?

    Vielleicht sollten wir den Wandel im Migrationskurs (der nicht neu ist, sondern schon seit 2021 durch die Ampel signalisiert wurde) nicht als "Rechtsabbiegen" bezeichnen, sondern als eine vernünftige Neubewertung in anderen Zeiten? Es ist wahr, dass es unfassbar schwierig ist, Straftäter abzuschieben, insbesondere, wenn diese bei der Einreise oder danach ihren Pass "verloren" haben und keine Nationalität mehr eindeutig nachzuweisen ist.

    Menschen, die Asyl benötigen, können nach geltendem internationalen Recht legal anreisen und ihren Antrag stellen. Einen Aufenthalt durch eine illegale Einreise zu erzwingen ist nicht okay und hat nichts mit Links oder Rechts zu tun.

    Why limit immigration?
  • If immigration leads to more unemployment, then that is an economic problem, especially in the hypothetical case where the social benefits system is getting more and more strained by an influx of unemployed people. But generally, I think that you can expect that the immigrants will soon find employment. Besides that, there's the cultural aspect that @jet@hackertalks.com mentioned. You could also make the point that the country's infrastructure is more and more stressed as the population grows, but that is fixable and potentially counteracted by the labour potential of the immigrants themselves (i.e., qualified immigrant work forces can make a large-scale infrastructure overhaul possible that will lead to greater national capacities and a net benefit for the entire population).

    Aside from these things, I would argue that most of the other reasons boil down to xenophobia or racism.

    Windows NT vs. Unix: A design comparison
  • Unix is literally the most important operating system (specification) family on the planet. Even bigger than M$ Windows. You've got all the Android phones, all the Apple iPhones, macOS, FreeBSD and all the GNU/Linux distributions. Unix-like installed base is by far the largest of any on the planet.

    Is the bitwise AND of subnet masks and IP addresses redundant?
  • It's nostupidquestions after all :( I am not saying that anyone ever did anything worse, my question is aiming at the answer for why the current approach is the way that it is, on a technical level.

    Is the bitwise AND of subnet masks and IP addresses redundant?
  • Yep, I agree. Though one could make a hypothetical argument for expanding the array dynamically when needed. Of course, due to the varying sizes of NIDs resulting from CIDR (which you correctly mentioned), you would need to have a second array that can store the length of each NID, with 5 bits per element, leaving you with 3 bits "saved" per IP address.

    That can end up wasting more memory than the 32-bit per NID approach, e.g., when the host identifier is smaller than 5 bits. And there's the slowness of memory allocation and copying from one array to another that comes on-top of that.

    I think that it is theoretically possible to deploy a NID-extracting and tracking program that is a tiny bit more memory efficient than the 32-bit implementation, but would probably come at a performance overhead and depend on you knowing the range of your expected IP addresses really well. So, not useful at all, lol

    Anyway, thanks for your contributions.

    Is the bitwise AND of subnet masks and IP addresses redundant?
  • Though I would like to clarify that maybe my wording was a bit confusing. By "string of bits", I did not mean the term as it is typically used in programming language environments, but rather a raw binary sequence, e.g., the first 24 bits of an IP address, therefore allocating 3 bytes of memory for storing the NID.

  • Okay, that makes sense. Thank you.

  • So I understand that the subnet mask provides information about the length of the routing prefix (NID). It can be applied to a given IP address to extract the most significant bits allocated for the routing prefix and "zero out" the host identifier.

    But why do we need the bitwise AND for that, specifically? I understand the idea, but would it not be easier to only parse the IP address string sequence of bits only for the first n bits and then disregard the remainder (the host identifier)? Because the information necessary for that is already available from the subnet mask WITHOUT the bitwise AND, e.g., with 255.255.255.0 or 1111 1111.1111 1111.1111 1111.0000 0000, you count the amount of 1s, which in this case is 24 and corresponds to that appendix in the CIDR notation. At this point, you already know that you only need to consider those first 24 bits from the IP address, making the subsequent bitwise AND redundant.

    In the case of 192.168.2.150/24, for example, with subnet mask 255.255.255.0, you would get 192.168.2.0 (1100 0000.1010 1000.0000 0010.0000 0000) as the routing prefix or network identifier when represented as the first address of the network, however, the last eight bits are redundant, making the NID effectively only 192.168.2.

    Now let's imagine an example where we create two subnets for the 192.168.2.0 network by taking one bit from the host identifier and appending it to the routing prefix. The corresponding subnet mask for these two subnets is 255.255.255.128, as we now have 25 bits making up the NID and 7 bits constituting the HID. So host A from subnet 192.168.2.5/25 (HID 5, final octet 0000 0101) now wants to send a request to 192.168.2.133/25 (HID 5, final octet 1000 0101). In order to identify the network to route to, the router needs the NID for the destination, and it gets that by either discarding the 7 least significant bits or by zeroing them out with a bitwise AND operation. Now, my point is, for identifying the network of which the destination host is part of (in this case, the host is B), the bitwise AND is redundant, is it not?

    So why doesn't the router just store the NID with only the bits that are strictly required? Is it because the routing table entries are always of a fixed size of 32 bits for IPv4? Or is it because the bitwise AND operation is more efficiently computable?

    I recently wanted to buy a product from a manufacturer and luckily they offered PayPal as a payment method. However, after I signed into my PayPal account, it wouldn't show my bank account as a payment option and instead prompted me to add a card or bank account, despite my account being fully confirmed and direct debit activated. PayPal customer service reps told me that maybe the retailer blocked direct debit through PayPal and I should try adding a credit card, however, why would they do that if they offer non-PayPal direct debit anyway? The customer service reps further told me that my account was in good standing, so there shouldn't be any problems with trust etc. Have you ever encountered an online shop that refused direct debit when handled by PayPal?
