  • I used the textbook as Oppenheim in my graduate DSP course, with the textbook by Proakis as a secondary reference. I don’t really love the Oppenheim book. I’m not super familiar with the Proakis DSP book as a result, but I think his textbooks on Communication Systems and Digital Communications are very well written. The Van Trees I find really well written and I really like (however the topic is also most interesting to me). All of them require you to study them though, I’m not sure what you mean by that.


  • Really depends what you are into. For general concepts, Discrete-Time Signal Processing by Oppenheim and Discrete Signal Prcessing by Proakis are standard textbooks.

    If you’re interested in communication or radar systems, array signal processing is very closely linked with discrete signal processing but with more linear algebra and statistical concepts. Optimum Array Processing by Van Trees is a great textbook for this.









  • It’s totally obscene. I traveled to the USA recently for 5 days and my options were:

    i) Pay Telus $14/day * 5days = $70 (plus tax)

    ii) Buy a US 30GB 10-day esim for $11.27 taxes included.

    Plus in option i) I’d be using the data from my own data plan. Unless you really need to be able to use SMS and receive calls, it’s really a no brainer. Especially with how easy esims are to setup, I just had to switch a setting in my phone when I crossed the border. Crazy part is, if it was ``only" twice the price, I’d probably have just paid Telus.



  • The $38.9 million fine Cineplex has now been handed is equivalent to the amount it collected from consumers through the $1.50 online booking fee between June 2022 and December 2023.

    This is already way harsher than corporations usually get but I can’t help but wish it was more that all they got because they come out with no actual loss.

    GOG’s refund policy is good enough that preordered games can get refunded anyways if they are poor. The ability to preload was worth preordering considering the practically zero downside with GOG. I could have refunded after playing but my computer was powerful enough to push through and still have the performance not be too poor except in a select few areas.

    But regardless of the preorder situation, suggesting that this is things done right and we complain too much because there were 4 years of updates improving the state still is a strange stance to take. A game shouldn’t be released in a state that it needs 4 years of updates for most users.

    Huh? For those of us that paid $90 for a broken game, I think we have a good reason to complain that four years later the game still needs repairing. Sure a company like EA or Ubisoft wouldn’t have fixed it but nonetheless there is a fair reason to complain. CDPR wants to salvage their reputation which is why I bet they are doing it—EA and Ubisoft don’t have a reputation to salvage at this point.

    My experience is the opposite. The hours 3-6 feel more dangerous to me because many drivers are in a rush and very uncourteous. At night there are just way less cars on the road and in general they are much more courteous. However I generally don’t ride light enough for them to suffer from very bad sleep deprivation.
