  • Upload bandwidth doesn’t magically turn into download bandwidth

    Actually, it does. Various Cable and DSL standards involve splitting up a big (eg, measured in MHz) band of the spectrum into many small (eg, around 4 or 8 kHz wide) channels which are each used unidirectionally. By allocating more of these channels to one direction, it is possible to (literally) devote more band width - both the kinds measured in kilohertz and megabits - to one of the directions than is possible in a symmetric configuration.

    Of course, since the combined up and down maximum throughput configured to be allowed for most plans is nowhere near the limit of what is physically available, the cynical answer that it is actually just capitalism doing value-based pricing to maximize revenue is also a correct explanation.









  • That pin can be found for $30 or $35 on on ebay here and here, where it is described as being from the 80s and as an “employee pin”.

    I was thinking that this might have been something aimed specifically at technology buyers in US schools in the 80s or 90s, to whom Apple offered substantial institutional discounts in a (relatively successful) effort to dominate that sector. However searching the phrase “does more costs less” i found this TV spot advertising the Quadra 605 which at $1000 was the cheapest computer Apple sold when it was introduced in October 1993 (and allegedly cheaper than something else they refer to as “PC Leading Brand” 😂). That system was sold under the LC and Performa brands up to 1996, but it was only sold as a Quadra until October 1994, so, to answer OP’s question: that slogan was in use at least sometime in that year.





  • If copyright holders want to take action, their complaints will go to the ISP subscriber.

    So, that would either be the entity operating the public wifi, or yourself (if your mobile data plan is associated with your name).

    If you’re in a country where downloading copyrighted material can have legal consequences (eg, the USA and many EU countries), in my opinion doing it on public wifi can be rather anti-social: if it’s a small business offering you free wifi, you risk causing them actual harm, and if it is a big business with open wifi you could be contributing to them deciding to stop having open wifi in the future.

    So, use a VPN, or use wifi provided by a large entity you don’t mind causing potential legal hassles for.

    Note that if your name is somehow associated with your use of a wifi network, that can come back to haunt you: for example, at big hotels it is common that each customer gets a unique password; in cases like that your copyright-infringing network activity could potentially be linked to you even months or years later.

    Note also that for more serious privacy threat models than copyright enforcement, your other network activities on even a completely open network can also be linked to identify you, but for the copyright case you probably don’t need to worry about that (currently).








  • They only do that if you are a threat.

    Lmao. Even CBP does not claim that. On the contrary, they say (and courts have so far agreed) that they can perform these types of border searches without any probable cause, and even without reasonable suspicion (a weaker legal standard than probable cause).

    In practice they routinely do it to people who are friends with someone (or recently interacted with someone on social media) who they think could be a threat, as well as to people who have a name similar to someone else they’re interested in for whatever reason, or if the CBP officer just feels like it - often because of what the person looks like.

    It’s nice for you that you feel confident that you won’t be subjected to this kind of thing, but you shouldn’t assume OP and other people don’t need to be prepared for it.
