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 Boléro) 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'}});

This Week I Learned 2018 - Week 31

Last week post or something from the archive.

What is the most mind-blowing thing I've accidentally found out about Thinkpad? Fn + Space toggle the light at the top of the monitor, near the web cam. Seriously?

為什麼時間感覺有時過得快、有時過得慢? 我之前已经有提到随着年龄增长,你就会觉得時光飛逝,但是只是用岁月来简说如此经历,一点都没有科学根据。然而,啾啾鞋的解说,终于让我也明白为何我会有如此体验。简单的说,是我们自己的脑作怪。仔细说明,理由有三。第一,暂时性幻觉 (Temporal Illusion)。第二,伸缩效应(Telescoping Effect)。第三,停表错觉(Chronostasis)。

What to do this too much advice? (via HN) We are always looking for confirmation rather than advice. Furthermore, advice is always cheap anyway.

Are there receivers to avoid on the used market? Any Onkyo receiver with HDMI daughter board. I've confirmed this with local audio shop which sells a lot of second hand AV receiver. Why so? It seemed their circuit board was designed to run everything (analogue, optical, and coaxial) through the HDMI board. And when you have faulty HDMI board, nothing works. The funny things is browsing through some YouTube videos, the fix was quite easy by replacing the faulty capacitors. Does the same problem exists for newer AV receivers. Not sure but discussion with the shop owner indicates that it's wise to pick some other brands instead.

Is the Sony Core SS-CS5 bookshelves speakers most unknown and underrated speakers? I'm quite surprise that one Redditor claimed that it's even better than Klipsch R-15M, KEF Q1000, Elac B5 / B6, or even the popular Pioneer SP-BS22-LR. My research indicates that this is true to a certain extend, one reviewer mentioned that the pro of this speaker is the clarity of the music but lacking in the mid range and bass. The clarify of this speaker was proven that someone even suggested that we can using this pair as center speaker instead. In other words, not a all rounded speaker. And by the way, Elac and Pioneer are hyped not because of the quality but due to a certain quality within that affordable price range.
