dried algae / organics on tiles

tested ：

wire brush, manual, and on drill

acid, sodium bicarbonate, sodium hydroxide

--

dirt : is probably mostly dried algae

--

If trying this again, 

(a) use 3000 psi waterjet

(b) use water and wire brush first ; if not easy, then get NaOH flakes and saturate wet surface, soak for an hour, add more if not saturated, keep wet ; then repeat brush

(c) not sure if the acid helped, but it might work as an alternative to the NaOH ; but if you use acid, you should probably neutralise the area before wire brushing

what if \ apple sideloading and egovernments

What if the Malaysian government were to run its own Apple appstore?

Why? Well what if gov.my were to run the country on iOS? Standardise everything. Centralise app development. Consolidate all data to PADU. Electronic government here has been a mess, all my life, despite the brouhaha of Vision 2020. Outsource infosec concerns to a US company ... loss of sovereignty? Maybe, not necessarily.

The cheapest new iPhone is MYR 2500. The country's population is estimated at 34 million people, soon. It would cost 20+% of the national budget to buy everyone an iPhone, before program discounts, buy-backs, substitutions with already-owned devices, and a total asset tracking registrar for all devices.

I don't own any Apple goods, and I don't have a need to in the foreseeable future. But it was a good opportunity to riff on their appstore sideloading developments.

more hegemonic ranting

Usually I manage to filter them out of my surroundings. But every now and then life admits upon me a familiar kind of idiot. They take the roles of parents, bosses, friends, business partners, customers, vendors, strangers, lovers ... the list goes on. Their childlike rage expresses that "one ought to know better", as they are staunch believers in common sense. But when queried for structure, they cannot provide it. And it is not their fault, that they are ignorant. Society as a whole often fails to properly educate its citizens. That is why this is sad.

Physical Anxiety + Adultism ( as in, a form of prejudice )

/// Reflections on physical anxiety ... and perhaps, adultism ///

( As seen in society, including workplaces. Of course, the poorer the workplace, the poorer the masking of unresolved anxieties - though some would disagree. )

/ The overly spartan version : /

- a child is not aware of their own problems, and certainly not of the solutions to those problems

- an adult defines a child's problems, and defines those problems in terms of solutions acceptable to the adult ( adultness is self-defined, by asserting that there are problems in the world ; adolescence is the transition from childhood to adulthood )

- a child, for example, cries and is made to cry less by an adult via various mechanisms ( the psychobiology of this is always a fun party topic ... do you help crying babies because it makes you feel good, or because it makes the babies feel good ... segue to metaethics )

- an adult, recognising in themselves the cause for their own crying, may resolve their own cries

- it is socially acceptable* for adults, to first cry, then finding no others responding, resort to self-resolution ; one that cannot self-resolve, is deemed* disabled ; one that cannot self-resolve, and furthermore begrudges the absence of resolutions, is deemed* furthermore disabled for their rejection ("denial") of what others deem to be adultness

/ The more nuanced version : /

- all the mores and norms marked with a "*" above, of course, vary from society to society

- it is up to each society to decide its low- or high-context

Sound engineer gripes

I read that Kamala Harris' public speaking style has not gone well. So I looked up some examples of her speeches. Here's a technical-ish view.

She struggles to be heard because the amplification is too weak - and the stress is apparent as her tone rises to higher frequencies. The higher the stress, the higher the tone of a voice, and the more it warbles. You can't do mass modification on the audience to fix sexist and racist interpretations of this phenomenon. So it's much easier to fix the gear instead.

1. Raise the amplication, or move the mic closer.

2. Train her to move closer to the mic.

3. The resulting savings in energy can be rechanneled to articulation, and slower speech, at whatever register is most comfortable for the speaker.

The lady needs a better sound engineer and speech coach.
