can you pull ethernet cable along power cables, wherever they are?

regular ethernet should work on this kind of distance, but it means digging

Mate do i have just the right thing for you, but it requires some soldering. It’s also probably cheapest solution working over longer range than you need

First you need two directional antennas. Use this https://lea.hamradio.si/~s53mv/wumca/cup.html the 13cm design specifically. Design of the dipole element is on another page https://lea.hamradio.si/~s53mv/wumca/sbfa.html They’re using hard to get semirigid coax but you can really just use common RG178 with braid tinned to make it stiff. This way you don’t have to leave D section they way they did, you can just solder core to the shield at the end while preserving total length (or ~1-2 mm less, because wifi is slightly higher frequency; 53-52 mm total). That dummy cable thing can be just any stiff piece of wire. Good way to get this would be getting a pack of u.fl-SMA pigtails, which you can also use for connection.

You also don’t need special aluminum housing like they do, cookie tin of the right size would be sufficient, or any other container of similar nature. If you can’t weatherproof it, putting it inside on windowsill is also fine

Then, plug TL-WN722N into it, or some other single-antenna thing, and you’re set. This one connects over USB and has removable RPSMA antenna, so you can connect it easily with correct cable (SMA plug - RPSMA plug)

to your new directional antenna. This thing works well over 200m distance, provided clear line of sight, and probably more than that

in my country it used to be like this for 50 years, you get flat rate per day, counted up to fractions of day, separately for accomodation and food + everything else. you only have to keep transportation tickets

behold, disruption

i don’t mean beta-oxidation, it’s just a series of separated normal reactions. i mean something like this: when first learning about ketones, you might learn about aldol condensation, which has enol as a nucleophile and another carbonyl as electrophile. at some other point you might learn about strecker reaction, which has iminium ion as electrophile and cyanide as nucleophile. but really, what you can do is mix and match, and you can pair enolizable ketone and iminium (mannich reaction) or carbonyl and cyanide (cyanohydrin formation) and then generalize, for example you don’t need strictly ketone for mannich, you can use any electron rich conjugated system like malonate or nitroalkane anion (henry reaction) or phenol or indole. to figure this out you need to study mechanisms. these last two are usually treated as variants of friedel-crafts reaction, but really categories like this are fake

and to get that right, you need to know how these reactive intermediates look like, how reactive they are, what influences their stability which means that ochem starts with discussion of carbocations, carboanions, radicals, their shapes and orbitals involved, hyperconjugation, solvent effects and the like. and then first reactions taught are sn1/sn2, because these showcase these fundamentals nicely, and from there, it’s about introduction of more compound classes

we only had synthons introduced during lecture at around 4th year, and only for ochem path, it’s not doing a lot at that point and imo would have much more impact right after ochem intro course

i always thought that the idea of synthons should be taught early on https://en.wikipedia.org/wiki/Synthon

i’d say it’s more important to learn mechanisms because this way you can notice these patterns of reactivity easier. at some point you’d only get new reactions that are really just pieces of other reactions you know put in a new way

there’s zero reason to make chart like this, it’s both barely comprehensible and touching surface level stuff only (where are palladium couplings for one)

i mean it would be hard to imagine 20 years ago precise ways things could get worse, and then

you know, in comparison dubya at least tried to have this kind of diplomatic subtlety that is nowhere to be found in current administration

behold: vibe driving (or maybe it’s just DUI for silicon)

random sample of 1000 people is a decent one, they even included error bars:

The poll has a margin of error of plus or minus 3.1 percentage points at a 95 per cent confidence level.

These things are under high voltage, so no. And then there’s several kg of mercury inside

no, but they will also kill you (but not by magic)
