I'm remembering a difference in the design of Commodore computers like the Vic and 64, versus the Atari 8-bits, and game consoles from the likes of Atari and Nintendo: they all had cartridge slots, but Commodore put them at the back instead of on top. From a technical perspective this was a minor...

I would like this awk command to replace the last underscore of column 2 with a tab. As it is now, it replaces the last underscore in each line with a tab, note that each line may have a different number of underscores in the columns. I have tried many things to direct the command to work only on...

I have seen o used most commonly as the Spanish word for "or". I am wondering if this can be used interchangeably with the new word for "or" that I discovered, u. By interchangeably I mean I would imagine "esto u aquello" and "esto o aquello" should mean the same right? Both should translate to "...

Why when trading gold apart of purity measurement its mass is always measured worldwide with a balance and not a scale?

I am trying to build a power supply in the following wehnelt/electron source configuration: The high voltage power supply is a DC supply with maximum of 30 kV, milliampere current range. The filament current supply is an AC supply of only a few, certainly less than 20 V. To power the supplies, ...

Different kinds of forests exist where I live. My favorite kind is composed predominantly of hemlock, striped maple, and silver birch. I've noticed these species often coexist in the same area. Other areas are dominated by red pine, or hardwoods, or beech and ironwood. What do you call areas that...

Is there a popular expression in English equivalent of Russian of this proverb? Water wears away a stone. Meaning step by step eventually we (it) will get there (reach the goal, etc.). It also can used to mean that harm or something undesirable can be done over time.

I have 4 steel pipes installed in a square pattern, 11' tall in my backyard. I want to install steel cable (wire rope) between the pipes to attach the shade sails. I want to drill a hole straight through the middle, at the top. (I probably should have drilled the holes before installing, but too ...

I'm proofreading English translations of Spanish scientific articles for journals. The translations are very good, but I keep coming across "allow to" without a subject, which sounds odd to me. The text says something like "This new method allows to streamline the process". Shouldn't it be someth...

A zonogon is a polygon that is convex and is made only out of pairs of parallel sides with the same length. Any regular polygon with an even number of sides is an example of a zonogon.

A try to capture the informal notion of "this sentence is not provable in less than $n$-many steps" where $n$ is a concrete natural. Use the diagonal lemma to coin the following sentences, per each concrete natural $n$: $\zeta_n \iff \ulcorner \zeta_n \urcorner \text { is not provable in }< S_n(0...

Do attributive-only adjectives like 公共 or 男/女 take 的 at all when modifying a noun? I realize that they take 的 when in '是—的' construction. But is it correct to say 公共的建築 or 男的律師. Or can one only say 公共建築 and 男律師?

Assume a UTXO created in block n with the output using a relative timelock of s blocks (s OP_CHECKSEQUENCEVERIFY). What is the lowest blockheight which may contain a transaction spending that UTXO? Bonus: At what height will such a transaction be eligible for relay on the network?

I found it interesting that all three popular Vietnamese Bible translations say something like this (translated back to English): The fool mocks at sin but the righteous has the Lord's favor. (Fun fact: Vietnamese words don't have plural forms so it can either be "the fool" or "the fools") This...

My org recently integrated Twilio with CiviCRM and while we're excited to start using something for SMS that's connected to the database, it doesn't look like we'll be able to send multimedia (MMS) pictures, etc. through the system.

Descartes’ cogito has been discussed and, in many’s minds’, refuted ad nauseam. Anywhere you’ll read about ‘nothingness’, you’re likely to encounter some discussion on Descartes and his self-believed findings in the Meditations. What ‘thought’ is, the passage of time, the subject ‘I’ and the pred...

I am trying to analyze images of elliptical laser beams that are striking 'ground glass' surfaces. I need to determine the size, position and orientation of the ellipse that represents the boundary of the beam. The images are grainy due to random scattering from the irregular surface of the grou...

This might be rather elementary but I can't seem to find what's wrong with the following argument. I suppose it's something rather trivial. For operators $T\in B(\mathcal{H})$ We say that $T_i\to T$ weakly if $\forall x,y\in \mathcal{H}$ we have $$\langle T_i x, y\rangle \to \langle T_i x, y\rang...

Especially with chatGPT now, there is a lot of interest in generative models for healthcare for creating synthetic patient data to amplify patient counts, e.g. for rare diseases. These are then supposed to be used for purposes of statistical inference, e.g. to compare patient outcomes, estimate r...

I am trying to recall a short story from around 40 or so years ago. It involves two astronauts walking on the surface of the Moon and they are effectively blinded when their helmets become covered in moondust. If I recall, they try to rub it off but some sort of static electrical effect makes the...

I am learning about fiber bundles and I understand both the formal definition and the intuitive picture of the space being "twisted". However one point I am having trouble with is why we cannot express a fiber bundles in terms of a product. More specifically, let $\pi: E \rightarrow M$ be a fiber...

So I have a few extension leads all are 13A rated but the cable length is too short just 1 metre. It would be cheaper for me to rewire them than buying new extension leads. I bought a reel of the correct cable rated for 13A and have rewired one. However just have a query in regards to the wiring ...

Any idea how I am supposed to interpret this component? I would not have expected a gold in third position for a resistor with 5 colors. Edit: this other thread gives explanation as to how to interpret a gold in third position on a 5 band resistor, but points out that the 5th band would then be ...

There is a useful result when studying lattices that the sum $\sum_{m,n}' (m^2 + n^2)^{-r/2}$ converges for $r > 2$, where the sum is taken over all pairs of integers $(m,n) \neq (0,0)$. I'm curious whether the condition $r > 2$ is really necessary or not. Does the sum $$\sum_{m,n}' \frac{1}{m^2 ...

In preparation for a future campaign, I'm poking at building a homebrew cleric domain exclusive to Tiamat. One of my design goals for the build is to lean into Tiamat as the god of chromatic dragons, and keeping damage-related features as open to the full range of chromatic damage types as possib...

Simply put, let's say there is a portal that leads to the past, and that it's "catching up" : an observator from the present looking into the past sees time go faster, and an observator in the opposite direction would see it go much slower. Let's say the speed ratio is 3, for example, or n to gen...

I'm new to this. I would like the first line of footnotes to be indented, like below. I don't know what the code is, and where to put it in my template.

And you know that God anointed Jesus of Nazareth with the Holy Spirit and with power. Then Jesus went around doing good and healing all who were oppressed by the devil, for God was with him. (Acts 10:38) Does this verse say that Jesus was given power by God to work miracles? If so, how can we s...

When you web-search an answer for how airliners maintain cabin air breathability, the typical answer you get is that bleed air is the key: new air comes in from the outside and gets mixed with old air. But - these days, some airliners are bleedless, like Boeing's 787 for example... So, what maint...

Let $G = \langle A \mid R \rangle$ be a finitely presented group, given by a finite presentation. If $G$ is abelian, then we can verify this fact: simply verify the fact that $[a, b] = 1$ for all generators $a, b \in A$ (this can be done by enumerating all words equal to $1$ in the group). That i...

We have a series $\sum_{k=3}^\infty k * \frac{(\frac{1+\sqrt5}{2})^{k-1}}{2^{k-1}}$ and I want to compute it like that: let's say that $a = (\frac{1+\sqrt5}{2})^{k-1}$. Then we have $\sum_{k=3}^\infty k * \frac{a^{k-1}}{2^{k-1}} = \sum_{k=3}^\infty k * (\frac{a}{2})^{k-1}$. I tried to present it ...

I have not worked for the first half of this year and have some modest dividend/interest income that would end up being less than $1000 in taxes by the end of the year, so I have not been paying any estimated taxes on that income.

I am a US citizen and was crossing a land border into the USA the other day. The border guard not only asked me where I was going and who I was going to see, but also seemed particularly curious and asked various follow-up questions. The same scenario then repeated itself with another border guar...

I am in an office band and have to be able to play two different instruments. We are currently in a rehearsal studio that has an 88-key on the bottom and a synthesizer on top.

A word for when an artist builds up their ability to paint, but over time their art starts reverting. Or perhaps a child, once magnificent at playing the guitar, begins to pluck the wrong string and slur the notes, eventually becoming mediocre.

Is it possible for polar nights at one pole to be 8 & 1/2 months long without significantly messing up the climate?

I'm trying to analyise methylation data using GEO, in order to conduct a multi-omics analysis. The SubSeries I am referring to is GSE73303. Unfortunately, the code used to inspect it produces empty file, so I downloaded tar files, as I found on bioconductor forum (ref. this). I was able to downlo...

Given $f(x)=\frac{1}{x-1}$, find $δ$, such as if $0<|x-2|<δ$, then $|f(x)-1|<0.01$. Original problem is below picture: From figure or formula $f(x) = \frac{1}{x-1}$ we can get $f(2) = \frac{1}{2-1} = 1$. Because we need to guarantee $|f(x)-1|<0.01$, now we have know $f(2) = 1$, so we can get $0.99

Let $f:\mathbb{R}^2\to\mathbb{R}$ such that $f(x,y)+f(y,z)+f(z,x)=0 \text{ } \forall \text{ } x,y,z \in \mathbb{R}.$ Show that there exists a $g:\mathbb{R}\to \mathbb{R}$ such that $f(x,y)=g(x)-g(y).$ This was question $A1$ on the $2008$ Putnam. My attempt is given below. Put in $x=y=z$ to get ...

So I don't think positions like existentialism exist in Buddhist philosophy. I say this because the whole framing of causality is fundamentally different in Nagarjuna's treatise of dependent origination, so one doesn't actually cause meaning (in the traditional sense) What were the Buddhist schoo...

I'm a mathematician who has taken an interest in philosophy in the past few years.
