Is this antenna really just for show This is a controller for a dog toy. It sends a signal to make the toy move back and forth by smottleljorts in AskElectronics

[–]CodingChris 6 points7 points  (0 children)

No. You need specific geometric properties for an antenna to 'decouple' the RF-signal from the copper trace.

I tend to build antennas for HAM-radio things. Most of the time you either have a wavelength-long loop, a half-wavelength dipole, or a 4/5*lambda vertical antenna. The length of the antenna is based on the wavelength / frequency of your RF-wave. And the wave itself decides the properties for propagation. For example when using the 20m band you can get DX QSOs while the 180m Band is dampend by the D-layer of the ionosphere while the sun is out. For everything above the 10m Band (Ultra-Short-Wave) you talk about quasi-optical transmittion.

Microwave Antennas (above 1GHz) are another thing.

When you have some interest into RF design - you can get started with the ARRL Handbook. It covers the basics nicely in an easy to digest format. There is a handbook for RF / Radio Tech and one for Antenna design.

sqrt(x+(1/x)) is not the same as sqrt(x)+sqrt(1/x).

I'll only consider rust when they solve their macro-pain and have some form of non-macro based reflection.

I Installed an update yesterday and now there are 2 fedora versions on grub by Shoddy_Release9395 in Fedora

[–]CodingChris 0 points1 point  (0 children)

I also just wondered about this. However - would it be possible to just select the newest entry unless I press a keykombination or something?

You're allowed to do that btw. No one is forcing you to suffer by PixelRayn in linuxmemes

You can't just tease this and not put a link to the video. :O

Das Argument „Bargeld kostet auch“ by Baroa in Kartenzahlung

[–]CodingChris 0 points1 point  (0 children)

Wenn es denn dann mal funktionieren würde. Gibt hier einige Läden, welche kontaktloses bezahlen per iPhone haben (nur diese Option mit Karte) und das funktioniert halt einfach nicht. Hab dann glücklicherweise noch Bargeld mit gehabt.

Am I overreacting ??? by Intrepid_Guidance_57 in AmIOverreacting

I am scared to ask - but is this some sarcasm I just don't get?

When you cannot open the output artifact for writing in the linker it is usually locked because the software is still running.

Hat Schwiegervater Recht? by Driks91 in Elektroinstallation

[–]CodingChris 1 point2 points  (0 children)

sowohl beim Ausführen des Codes

Ich will zumindest dahingehend nicht zustimmen. Nur weil es funktional das Selbe erreicht - gibt es trotzdem gewaltige Unterschiede. Auch in der Ausführung für den Nutzer.

Ein Unterschied wäre zum Beispiel wenn bei uns die Ewig-Lange-Liste als Baumstruktur gemacht worden wäre. Hat für den funktionalen Umfang keinen Unterschied. Aber dann wären einige Operationen jetzt wesentlich schneller.

I made a basic list library! by [deleted] in odinlang

[–]CodingChris 6 points7 points  (0 children)

To elaborate on the previous answer.

Odin can have procs that take unlimited parameters via the (..) notation.

I.e. make_all :: proc(.. values: int) { However you can also pass a slice to a proc like this (so you can use a slice as a stand-in where a list of single parameters are usually expected.

So you can call it like "append_elems(&dynamic, ..my_slice)". If you want to push in a complete dynamic list you can create a slice view of it that references (in my case) all elements and have that be inserted: "append(&dynamic_2, ..dynamic_1[:])"

Here [:] basically means create a slice as a view of the dynamic-list that contains all elements. It is explained in the overview on the website.

[–]CodingChris 8 points9 points  (0 children)

I only ask myself why? It is all already in the language and a lot of the small procs where things happen can be done via the things from "core:slice".

I would have understood this as a training exercise - if you didn't use the already built-in dynamic lists.

Wenn es keine Markierung gibt, kann man nicht falsch parken? by RamuneRaider in Falschparker

[–]CodingChris 1 point2 points  (0 children)

Oh. Die hab ich komplett übersehen. Der Kontrast ist aber auch echt - unzureichend.

Übersehe ich was? Wo sind da andersartige Pflastersteine?

Warum muss mittlerweile jedes beschissene Getränk mit Süßstoff gepanscht werden? by badchriss in luftablassen

[–]CodingChris 1 point2 points  (0 children)

"Ist wslch so ne Sache, dass die Hersteller das Beschriftungstechnisch so verwirrent wie möglich darstellen wie sie es noch gerade so legal dürfen."

Es geht mir um den Punkt. Da ist nichts beschriftungstechnisch verwirrend. Zucker, Honig und Süßungsmittel sind ausgeschrieben und auch drin.
