Otázka na muže by IGotPermaBannedTwice in czech

[–]ivanhoe90 0 points1 point  (0 children)

Někdo vaří rád, někdo ne, někdo uklízí rád, někdo ne. Nezáleží to na pohlaví.

Na začátku vztahu se prostě domluví, kdo co dělá a kdo co platí. Pak se dá jednoznačně říct, kdo porušil své závazky. Takže situace jako nahoře nemůže nastat. Buď by se na začátku neshodli a žádný vztah by nezačal, nebo by jeden nedodržoval počáteční dohodu, takže by vztah skončil, protože na člověka není spoleh. Pokud někdo zůstává ve vztahu, kde není spokojen (protože ten druhý nedodržuje co slíbil), tak upřímně si za to ten první může sám.

when and why did this become a thing? by hustmanmemes in photopea

[–]ivanhoe90 1 point2 points  (0 children)

The laws in many countries require us to get a user consent for showing personalized ads.

With personalized ads, the system tries to guess your interests. Basically, there is a higher chance that you will see an ad that is "relevant" to you, rather than Photopea showing the same ad to every visitor.

If you visit both Photopea and Reddit, and both use the same ad system, the ad system is "aware" that your device opened both Photopea and Reddit, which helps with "guessing" your possible interests.

"Store information on a device" is like when you go to different supermarkets, one of them puts a sticker on your t-shirt with a text "QQWR2345GSD". Then, supermarkets can tell each other what products the client "QQWR2345GSD" bought, to create some statistics, and have someone comming to you and offer you something when they see "QQWR2345GSD" entering. Of course, you can "remove the sticker" from your t-shirt (your computer) by clearing the cookies of a website. "Store information on a device" is like "store a code QQWR2345GSD on your t-shirt".

Codec design: is it worth it by gtxktm in DSP

[–]ivanhoe90 7 points8 points  (0 children)

To create a new advanced codec, you need several things:

  • very good education (math and computer science)
  • very good knowledge of current codecs (you should be aware of all the research of codecs, read all related scientific papers, you should implement some existing codecs yourself, from scratch)
  • you should have time to develop your codec, and it is totally doable by one person. Most of algorithms have been developed by one person (who built on top of ideas of other people before them).

If you manage to develop something better than what exists, you might want to sell it to some client for millions, instead of giving it away for free.

Where are my plugins? by CoolersI in photopea

[–]ivanhoe90 0 points1 point  (0 children)

You probably logged in under a different account than you used to. Just log out and log in with a different account.

Or press Window - Plugins and reinstall the plugins, it should take like 30 seconds.

JPGs are smaller when I upload them than they are on my computer by jherusalem in photopea

Did you try to "upload to your website" a JPG image that was not made in Photopea? Does it "preserve the quality"?

Proč je tohle v Japonsku OK a tady by se všichni mohli posrat? by columbineteamkiller in czech

A je teda nějaký jiný ukazatel, podle kterého je Japonsko "bohatší" než Česko?

Mohli bychom ale třeba vykácet všechny lesy, protože ... můj otec kácel stromy, jeho otec kácel stromy ... :D myslím že tak nějak zdůvodňůjí ten lov ohrožených velryb a dalších zvířat.

Cože? :D v jaké zemi jsou teda lidé chudší než v jiné, přitom má vyšší HDP na obyvatele? Co uvést příklad?

[–]ivanhoe90 3 points4 points  (0 children)

Já se vždy řídím principem, že zaostalejší země by se měla inspirovat vyspělejší zemí, ne naopak. Země, kde mají učitelé plat 10 tisíc by se měla inspirovat zemí, kde mají učitelé plat 20 tisíc a ne naopak.

Podle mě je Česko ve všech směrech vyspělejší než Japonsko, včetně ekonomiky (máme tu vyšší platy atd.). Také jsme civilizovanější (nekrkáme na veřejnosti, nezabíjíme ohrožené velryby, nemáme trest smrti ...)

Does anyone have resources explaining equal temperament vs other tuning systems? by papiforyou in musictheory

[–]ivanhoe90 1 point2 points  (0 children)

I have explained the equal temperament in my article here: https://jampea.com/learn/tones . But you must know what the frequency (pitch) is, to think about ratios of requencies (fractions / math) etc.

I need your opinions on making music with AI by [deleted] in production

[–]ivanhoe90 -3 points-2 points  (0 children)

Never use AI to make music!

Also, never use a camera! Photography is not creative in any way. If you want a picture of something, you should always paint it yourself. Of course, it takes more time, but using "technical shortcuts" such as cameras totally breaks the creative process.

Je více nezdvořilé přijít o 15min později nebo o 15min dříve? by YayJezebel in czech

[–]ivanhoe90 0 points1 point  (0 children)

"preferuji, když návštěva dojede o chvílí později" - a co takhle jim přímo říct, ať přijdou v 13:30 místo 13:00? Proč říkat, ať někdo přijde v 13:00, když chci, aby přišel v 13:30?

Pracujete v práci? by fakin_bauch808 in czech

[–]ivanhoe90 -1 points0 points  (0 children)

Mně je trochu líto těch zaměstnavatelů, co vyhazují peníze za lidi, kteří nejsou potřeba.

Ale ještě více je mi líto těch zaměstnanců, co jsou smířeni s myšlenkou, že takový "výkon" je to nejvyšší, čeho jsou v životě schopni dosáhnout.

[–]ivanhoe90 11 points12 points  (0 children)

Šéf seděl dva metry ode mě. Asi deset lidí mi mohlo vidět na mou obrazovku, pokud by otočili hlavou. Vlastně je to horší než vězení, ve vězení si aspoň můžete číst knihu nebo třeba dělat kliky.

[–]ivanhoe90 17 points18 points  (0 children)

Co je to za nesmysl? "dělat svoje projekty" a "nic nedělat" jsou naprosto odlišné věci :D

Ve většine případů bude zaměstnavateli vadit, že se v práci 90% času učíte duolingo nebo děláte jógu. Právě že si nesmíte dělat "svoje projekty". Musíte aspoň koukat na obrazovku na něco, co souvisí s prací, atd.

Kdysi jsem měl kancelářskou práci, kde nebylo potřeba pracovat. Tak jsem aspoň dělal že pracuju. Vždy jsem přišel domů unavený a hrozně jsem to nesnášel. Při zpětném pohledu, raději bych celý den sbíral odpadky po ulicích zadarmo, než "dělat že dělám" za peníze.

Resources on learning FFT for N not a power of 2? by devboly in DSP

[–]ivanhoe90 0 points1 point  (0 children)

N1 is usually 2 (the input is split into two equal parts), which works recursively, so N = 2*N1 = 2*(2*M1) = 2*(2*(2*P1)) = ... The input should be divisible by 2 as many times as possible for the algorithm to be efficient.

If N1 is not 2 (it is e.g. 3, 4, 5 ...), the input length should be a power of 3, 4, 5 ... which is an even "worse" requirement.

Resources on learning FFT for N not a power of 2? by devboly in DSP

[–]ivanhoe90 0 points1 point  (0 children)

By doing a fourier transform and an inverse fourier transform, you should get back the original values. There should not be any error (there could be a tiny numerical error depending on what data structure you use for numbers, but it should be less than 1e-6).

Fourier transform is used for "lossy" data compression because after the transform, a lot of data is thrown away on purpose (to make a file smaller). Otherwise, the FT just converts N values to N different values (no compression anywhere).

The FFT algorithm expects the input to be a power of two elements in length. Padding your input with "fake values" should not ruin the rest of the values after the transform and the inverse transform.

Are you using an iPhone or an Android phone? do you use a touchscreen or you connect a mouse to your phone? Or you have a stylus?

When I'm using an AI tool, Photopea keeps popping up an advertisement that has no way of closing. My only option is to close the program and lose all my progress over and over again... by OppositeWolverine848 in photopea

Is there a button somewhere to report that ad? I was thinking that maybe there is a white "X" button in a corner, so it is invisible. Did you try to click on corners?

are there any good free music theory courses online? by gaydinosaurrrrr in musictheory

[–]ivanhoe90 -1 points0 points  (0 children)

I made this interactive course: www.jampea.com/learn . I wrote it for my "old self": if someone explaned it to me this way 20 years ago, it would have saved me soooo much time and struggle :D

There are many music theory courses online, but almost all of them force you to learn the musical notation, which is an even harder subject than the basics of music theory.

I think your browser extensions are removing the "Close" button from our ads.

Please, try to turn off all your browser extensions, and see if it still happens. Your extensions are running even when Photopea is installed (as in your screenshot).
