This Week I Learned 2018 - Week 33

Last post or some random posts from the archive.

Do you need standups? Maybe you don't. (via HN) Some comments in HN resonate with me based on the experience of the implementation. Maybe is just me, but it does feels like cargo cult software engineering. Team culture, business culture, or management issue? Execution of the practice is still al lot to be desired. Interesting development days ahead.

What are Thonet & Vander speakers like? The sad case in MY here is that there is no way for us to purchase any good budget speakers. The funny thing is that this particular brand Thonet & Vander is readily available. Some local distributor have brought this in (why that particular distributor did no brought HiVi Swan to MY?). Nevertheless, as the comment suggestion, this is one of those OEM manufacturer which use European brand names to implies good quality. Back to the question, is this brand of speaker good enough? My personal opinion, mostly are multimedia speakers (something you bought for your kids) and Amazon's reviews didn't justify anyone to fork money on it (there are other brands exists in similar market, Edifier). Unless we have good review from NO Audiophiliethis comment shares my sentiment.

Which "budget" stereo amplifier to get? It's between Onkyo A-9010 and Marantz PM5005. Price wise both are the same and it's just the sound signature. For A-9010, I'm not sure that I need to replace the Samwah capacitor to Nichicon gold tune capacitor. However, different country have different version. However, I'm not sure the model sold here is EU (digital inputs and normal capacitors) or UK (better capacitors, no digital input, and Wolfson WM8718 DAC) version. Having digital input is good if you want to hook up to Chomecase Audio via Toslink input. Also, the loudness button (which increases sounds at low volume, good for classical music like BolĂ©ro) piqued my interest with the device.

Why not stick to amplifier like SMSL SA50 which is cheaper? Those class D amplifier is truly budget amplifier which missing quite a lot of features compare to amplifier like A-9010, a class AB amplifier. Furthermore, the output rating have been inflated. Class D amplifier should be sufficient enough for a small room.

Speaker wise. Just pair it up with a floor standing speaker if you don't want to invest a sub-woofer. The speaker's bass should be sufficient enough.

Encountered this error "Odd number of elements in anonymous hash..." and took me a while to figure out what went wrong with the the code. It turned out that Perl's hash will accept single element Hash without a key-value pair. Hence, the warning. I was surprised that this is not a syntax error. The example code below. See if you can identify the issue. Hint, the `foobar`. There is a good explanation at Stack Overflow on this warning message. Turn on warnings people!
my $result = $api->GetSomething({name => {'foobar'}});
