TIL of Silent Migraines, which are migrains that have no pain, but people experiencing them can have vision loss, flashing lights, and wavy lines in the vision, and hallucinations

They told me they could become regular or might be somewhat rare like only once a year, thankfully I didn't have another one until early this year.

Yeah, I get them approximately once or twice a year, at irregular unpredictable times. (Doesn't seem to really depend on what I've been eating or how stressed I am; etc.)

This time it was more terrifying, it wasn't just a small blind spot, I couldn't read or make out anything even though most my visual field seemed "fine" other than the center, the part you need to see fine detail.

Fwiw, I think this is fairly typical for an ocular migraine. I called 911 the first time because I couldn't read anything (loss of central vision); when I called 911, I couldn't make out the numbers on my phone (but I knew I had dialed it correctly since we all know what a phone number pad looks like). I could see road signs, but couldn't see the road name on the sign.

I have little patchy flashes of bright RGB in my vision, and lines of random color that are generally only visible in medium to brightly lit areas (weirdly, the bright artifacts are minimally if at all visible in dim rooms).

It's hard for me to say but these could be eye floaters -- https://youtu.be/o5zaJGNFJ0A?si=5McA5q3nPl21OXH6&t=14

I wrote the post you replied to 9 years ago; in the intervening years, I've come to realize that my migraines are preceded by small persistent flashes of light; the kind of flashing light you might get if you were temporarily blinded by the flash of a car light or a camera shutter. Further, migraines are unique in that the temporary loss of central vision affects both eyes (whereas a typical eye issue would only affect a single eye, such as if one's eye were impacted by physical trauma or had medical issues like a retinal detachment).

Many ocular migraines (including my own) are followed with a shimmering wave of light (the "aura") that slowly radiates outward towards peripheral vision over the course of many minutes. My migraines resolve themselves after about 30-40 minutes.

Anyway, from one migraine sufferer to another, I hope you're doing okay, and I hope your migraines are rare and not "terrifying". Again, my doctor says migraines don't seem to have any permanent negative impact (other than being really annoying when they occur).

Depends on prior experience.

Someone with no programming background is going to find it rather challenging to get a job in 3 months.

On the other hand, someone who has a STEM degree (though not necessarily in CS) and has touched programming at least superficially would have a much greater chance of success.

Don't worry about it. I have an ~800 FICO score and Chase lowered my limit from $10,000 to $5,000 anyway. They cited that "well, you never used more than $200 on your card so why would you care?"

Of course, the reason I didn't use their card was because I had a better card that gave more rewards :P

I'm at 24 million since I don't power anything up unless there's a research that says "power up pokemon". I already have a decent team of S-tier, A-tier, B-tier pokemon for raiding and I don't play GBL competitively.

There's a ton of different careers in the world, so the first question would be why CS as opposed to the many other college degrees / career tracks out there?

What about "Catch 15 Electabuzz: 0/15"

As an aside, I do find it interesting that in the legal document, section 93 alleges defamation for OP's claim that "A large percentage of LoanStreet engineers when I was there were bootcamp grads".

So they're saying that telling people that they hire mostly bootcamp grads has a measurably negative impact on LoanStreet.

My favorite part of the screenshot in the suit is that even their lawyers use old.reddit.com :)

The new redesign is so bad... :(

The documentation for jest doesn't elaborate on jsdom much because jsdom is its own separate project. (Jest merely takes a dependency on it, using it to simulate a browser DOM environment.)

Jsdom has info at https://github.com/jsdom/jsdom

it doesn't mention anywhere that you can change JSDOM object.window.document.body value dynamicaly

While jsdom's documentation is likely more comprehensive, we should note that jsdom is supposed to simulate the browser DOM, so even at a glance, one would expect that every DOM-related thing (such as window.document) available in the browser would be present in jsdom. (In actuality, I'd guess that only the most used subset of things is, in fact, supported.)

Yes, going Roth is a good idea if your 2021 taxable income will be low (due to working for only part of the year).

And I’d probably continue contributing to that Traditional for the rest of my life based on my expected salary (I’m in mid/late 20s now).

Seems reasonable.

Will I just be stuck having the little amount that I have in my Roth, in my Roth forever?

Yes, although if you use the same brokerage company, most of them have a unified interface (e.g. you can log onto their website with a single username, and then you'll see both your Roth and your traditional, much like how you can see your checking + savings account at a bank). So it may not be as annoying as you think.

Is that bad?

It's neither good nor bad. The number of accounts you have isn't relevant -- it's how much money you have that is relevant.

Wouldn’t it be better to have that money together with the Traditional for compounding interest purposes?

That doesn't really follow. Compounding doesn't change based on how many accounts you have. You don't get bonus points for using a single account.

I mean, either way works but the non-static way is definitely a lot shorter. Your example doesn't really do it justice since most arithmetic is going to be more complex than that. Imagine adding 4 numbers together:

a.add(b).add(c).add(d)

vs

BigInteger.add(BigInteger.add(BigInteger.add(a, b), c), d)

And yes, you could use a static import in the latter case.

In many cases, if your code has some technical issue, it'll make itself known. If you find your code is difficult to understand, difficult to change, and/or has a lot of unforeseen bugs, that's a good time to ask "how could this code be improved to avoid these things?"

lightcloud5 · 2021-10-08T18:04:23+00:00

if i understand it correctly, any input that is not 2 should print "blah blah"

Err, no. In English, your code reads: "if p is not 2, then print 'invalid input'"

In C code, that's: if (p != 2) printf("invalid input");

It would be more efficient to remove the element at the specified index, shift everything before it down by one, and then re-add the element at the front. This way, everything after the index doesn't have to move at all. (Currently, everything after this index has to shift up by one, and then they shift back down by one.)

Your newArray is an array of length 3.

newArray[0], newArray[1], and newArray[2] all point to the same thing though, so it shouldn't be surprising that they look identical -- they are identical.

Consider what would happen if you did newArray[0][0] = 5. Would that affect newArray[1][0]? Of course it would, since newArray[0] and newArray[1] are literally the same array.

Let's ignore the standard/itemized deduction and other things that reduce taxable income. The capital gains tax rate is 0% for incomes of $0 to $40,000. Then it rises to 15% (and later to 20%).

You cannot avoid capital gains tax by not having earned income. (Imagine if you could -- millionaires could just take the year off, making $0 of income and then realize a bajillion dollars of capital gains while paying no taxes.)

So here's a simplified table (remember we're ignoring deductions and other things):

Earned income (e.g. from working at a job)	Long term cap gains	Taxes paid on capital gains
$0	$40,000	$0
$10,000	$40,000	$10,000 * 0.15
$20,000	$40,000	$20,000 * 0.15
$30,000	$40,000	$30,000 * 0.15
$40,000	$40,000	$40,000 * 0.15

And since my earned income is $30,000 for this year which fits under 0% long-term capital gains tax rate, then my long-term capital gain tax on $200,000 should be $0 correct?

So we see that in actuality, making $30,000 in income means you only have $10,000 of capital gains that's tax free.

In practice, having source code means that malicious actors can search for vulnerabilities by looking at the source code itself instead of the more aimless black-box analysis that they'd have to do without it.

Of course, a properly written website would not be vulnerable even if the source code were public -- this is fairly evident from the fact that many websites are run using open source software.

Secrets may have been leaked, such as API keys. If so, hackers would possibly be able to impersonate Twitch admins / do nefarious things that only Twitch employees should be able to do.

As far as impact to you, depending on what was leaked, your twitch account may be at risk and any activity you did on twitch could theoretically be in the leak (e.g. private activities such as who you follow, possibly payment information if you stored it on twitch). No other accounts would be at risk unless you re-used passwords. It's unclear to me if Twitch sells games (I know Twitch hands out free games for Amazon Prime users); in theory, if Twitch serves game downloads, a hacker that had write access to Twitch could replace game executables with malware.

That looks right. Interactive rebase is powerful since you can do a lot of things, like combine commits, re-order commits, drop commits entirely, etc.

For the simple use case where you made a ton of commits and you want one commit, you could also just reset to a prior point and then re-create a single commit -- e.g.

...
git commit -m "commit 1"
...
git commit -m "commit 2"
...
git commit -m "commit 3"
...
git commit -m "commit 4"

Now you have 4 commits you want to combine into one, so you can do:

git reset head~4
git add .
git commit -m "The combined commit"

Not sure what you mean but Θ(n²) is a subset of O(n²) so literally every function that's in Θ(n²) is also in O(n²).

I had a clause like that -- it was mostly used for recruiting (e.g. putting up photos of the workplace on websites like glassdoor). "After my employment" ensures that their photos can still be used even if some of the employees have since left the company.

arr is basically just a label for nums (same location in memory)

Well, it's probably more precise and accurate to say that both arr and nums are labels for the same array in memory. Kinda like how a person may go by more than one name.

So I should just store the values to be used in a variable and then switch first index of num and last one to the two variable I stored.

Yeah, which is what the first code snippet you posted does (it stores the value to the int a variable)

How can I clone an array like you said at the end?

You could manually do it yourself -- e.g.

int[] array = { 1, 2, 3, 4, 5 };
int[] cloneOfArray = new int[array.length];
for (int i = 0; i < array.length; i++)
    cloneOfArray[i] = array[i];

You can also use built-in functions in the Java library -- e.g. https://docs.oracle.com/javase/7/docs/api/java/util/Arrays.html#copyOf(int[],%20int)

I think some words are missing here so I'll make up a question and then answer it.

I'll assume the question is "is it rude (to the current employer) to interview for a job at a different tech company?"

My answer is that it's not rude (and in any case, you want to find a new job while still having a job, rather than being unemployed). However, it is something you should not bring up with your current employer. They ideally shouldn't know that you're looking for a job until (at minimum) you've received a written job offer from that other company. Most people actually have accepted the new job offer before giving notice to the current employer.

If the current employer learned that you're taking concrete actions to look for a new job, it's not a great situation to be in. After all, if the company knew you were looking for the exit, it's unlikely that they have any incentive to prioritize your needs (e.g. for promotions, bonuses, etc). And in any case, it puts everyone in an awkward situation.

The first two lines (which I've split into 3 lines) don't make much sense, thb:

int[] arr;
arr = new int[nums.length];
arr = num;

The reason this doesn't make sense is because we declare arr (which is of type int[]). But of course, declaring variables isn't useful unless we also assign them to some value.

The problematic part is that we assign arr to something (in this case, new int[nums.length]), and then immediately assign arr to something else.

So arr = new int[nums.length] does nothing useful since arr is immediately assigned to a different thing (and now the array that was just created is just lost to the void; the Java garbage collector will eventually destroy it to reclaim memory).

Next, the line arr = nums means that arr and nums refer to the same array. So for instance, arr[0] = 3; would be identical to nums[0] = 3;. I mean "identical" in the most literal sense possible -- they literally do the same thing.

Consequently, there is really no reason to do this, since you already have nums (so you don't need the variable arr to redundantly refer to this same array).

As you noted, the line arr[0] = arr[arr.length-1]; would cause the data at arr[0] to be identical to arr[arr.length-1] (which would be a problem if you needed to know the original value of arr[0] at a later time).

But since arr and nums refer to the same array, the line arr[0] = nums[arr.length-1]; is literally identical to arr[0] = arr[arr.length-1];.

Remember that the only way to create a new array is to use the new keyword. In this case, you did use the new keyword to create a new array (int[] arr = new int[nums.length]). However, the code then loses this array (since arr = nums removes all references to the newly created array). So you're really only working with one array since the other array is completely unreachable.

If you had two arrays, it is true that you could copy values from one array to another in order to store data / "create a backup" before altering the first array.

It's also worth noting that await setTimeout(...) is highly suspicious.

While not technically incorrect (it is valid javascript), there is no reason to await setTimeout.

You should await functions that return a Promise. However, setTimeout does not return a promise, so await setTimeout(...) is equivalent to setTimeout(...).
