When I took the GRE in 2017, I got a really bad bloody nose right when the test started and I couldn't pause the test.

The person monitoring wouldn't let me have a bunch of tissues at the computer (Perhaps due to cheating concerns), so each time I needed a new tissue I had to raise my hand and she gave me one.

I didn't end up scoring very well.


Sounds like you should have bled all over the computer and let them deal with it. The lack of empathy they showed is abhorrent. Ugh. I’m sorry to hear that.


This happened to me during a written final exam, and yes I bled on the test a bit. Was using one hand to control the bleeding, but sometimes I had to turn pages, plus it was dripping all down my arm. Even the digital scan showed my bloody fingerprints on every page plus some large drop stains.


That's like suggesting you trash a hotel room because of some grievance with corporate policy. What actually happens is some innocent housekeeper gets stuck cleaning up the mess you made. The local test proctors are tasked with following very strict procedures and not given any room for discretion, especially if the testee isn't voluntarily withdrawing. It has nothing to do with an individual lack of empathy.


No it isn't, nothing is being trashed. The proctors should be better trained instead of required to behave like unsympathetic robots.


The fact that the proctor refused to break protocol while the test was in-session demonstrates proper training.


Do you think they have a written tissue protocol?


Absolutely.


I find that kind of hilarious. Especially as they are the ones providing the tissues.


> What actually happens is some innocent housekeeper gets stuck cleaning up the mess you made.

Thus costing the company money which, was the ultimate goal.

One person doing this can be thought of as an asshole, when a meaningful percent of people behave this way you get actual change and or lawsuits.


ironic. they demonstrate the exact lack of empathy they think they are deriding


The way some people have zero empathy hurts me a lot....


Sometimes you may need one when putting in those wooden rod things? Not sure what they are called.

I typically just use the butt end of the screwdriver when I have to put them in

Edit: didn’t see the other reply mentioning the same thing :(


> those wooden rod things

Dowels.


I like my name for them better!


One thing I dislike about using Reddit (At least when accessing the main page from a browser) is that I have to be logged into an account in order to sort comments.

Was this always a thing? I cannot remember if this was in the case in the past, and I don't really have a Reddit account that I actually log into ever.


I think potentially they cannot view the article due to region blocking?


Same here, where probably less than 0.001% of the population know who he was. I can't imagine what's the logic behind blocking something that doesn't consume measurable bandwidth.


How did you make those comics? Is there something that just generates the html for you?


Is there something that just generates the html for you?

Exactly. I rolled my own CMS just for this. No images, just html and superfast svg built from database parameters. I'll be launching a full webcomic only site by the end of the year. I hope to include source at some point. I'll keep you posted.


I did some googling since I was also curious and found this stellar article: https://energyeducation.ca/encyclopedia/Hydraulic_head

TL:DR: "Head differences of 100 meters or higher are considered high head. In this type of plant, water travelling through the turbine comes from a significantly higher elevation, meaning that the system needs a smaller volume of water to produce an equivalent amount of energy.[1] These systems generally also require smaller turbines since there is less water flowing through the turbine."


The ideal place for a hydroelectric dam is what's called a slot or "gunsight" canyon. Narrow and high, to create the best conditions with the smallest dam. Dams in wide, relatively flat places like along the Columbia River exist, but they are multi-purpose, built for flood control, irrigation, navigation (with channels and locks), and recreation benefits in addition to hydroelectric.


Props for finding a simple yet thorough article explaining many of the terminology used in other responses in this thread. Thank you.


There is also a file format called DICOS which is based off of DICOM which is used by the TSA and various inspection systems:

https://www.nema.org/directory/nema-councils/imaging-and-com...

If you've gone through security at a U.S. airport, the scanners use DICOS format to save scans of your baggage. Someone correct me if I am wrong though - it's possible only a subset of these machines use DICOS, I am not 100% sure.


Yes, I remember stumbling upon DICOS when I researched DICOM. Quite interesting application of the standard!


I recently went through the hiring process for a few companies and while most of them required several technical interviews, one of them never once had me do a coding test. I essentially kept going through the process just to see if they would make me an offer after three conversations (They eventually did make an offer).


Let's try an example with n=4:

1 ^ 2 ^ 3 ^ 4 ^ A[0] ^ A[1] ^ A[2] ^ A[3]

It might be early in the morning and I am missing something, but it has n-1 as its last index. Any insight is appreciated :)

Edit: There is a missing number in the array, thus its last index is n-2. Thanks for the correction, OP.


Premise: A is containing all values in range [1, 4] except one:

Let's say that, without loss of generality:

> 1 ^ 2 ^ 3 ^ 4 ^ A[0]=1 ^ A[1]=2 ^ A[2]=3 ^ A[3]=4

However, A is now missing no value. Contradiction.


But there are only 3 items in the array (for example 1, 2 and 4). So the last valid index is 2.


Ah. I was about to make an edit to my comment as you are correct :) Thanks!


I agree. Duolingo is great for learning vocabulary, but if you really want to learn a language you need to supplement this with listening to the language as well as speaking it.

I've been learning French and have been using Duolingo for vocab, but then I listen to a French-teaching podcast as well as trying to work on reading/speaking it.


I'm not at the stage where I can listen to it since it's such a fast language. I've been reading LeMonde newspaper and trying to decipher it that way. I live in Canada but the French here is quite different in each region; Quebec, Acadian, Métis. Duolingo French course is France French not Canadian French I think it's standard French aka Parisan.


There are podcasts for learning such as "Coffee Break French". Basically they start with very basic french and build up. This can be good for starting to learn to listen to french.

Regarding the differences between Canadian and France French, are there that many differences that it would make it difficult to understand someone from another region?


In addition to what others have said I can only offer anecdotal evidence.

I have friends and former coworkers some from Quebec, some from New Brunswick all fluently bilingual. We've all worked with people from France on projects and my Acadian friends remarked they couldn't understand a word the people from France said.

Although the reverse of that a friend went to northern France on vacation. When he was there he said everyone asked him where he was from he told them New Brunswick Canada. From what I understand Acadian (French dialect of New Brunswick, Canada) is older and closer to northern France than the Quebec dialect. I'm not sure if my friend meant the regional dialect or standard Parisian French, I'm pretty sure he meant the former.

And this may be totally wrong but I believe the southern France dialect (Occitan) is quite different than the north. I've had to call Monaco (I know it's not France) and I was surprised at just the accent of the French person speaking English. I've been around French all my life but southern France to me sounds like stereotypical cartoon French like Pepe LePew.

The entire history of standard French for their language is quite interesting. It's not been accepted for as long as you may think and there are many dialects.

edit: I think Canadian French has a lot of slang not used in France which makes it hard to understand. Kind of like a Cockney from England coming to the US, sure you can understand his language but not the meaning the way he uses words.


Native French here. One day I was in a place with 4 people from Québec speaking with each other. I could understand perfectly three of them, then it took me 15 minutes to understand the last one was speaking French too and not a foreign language. So, accent could vary quite a bit between region and people but most of the time it’s similar enough that there is no problem.


Definitely, it can be really hard for me as a native french to understand a canadian-french speaking if he has a strong accent.


What if you don't need listening or speaking skills, only reading? In your opinion is Duolingo a good fit for someone who only needs to learn to read the language?


Not the gp, but I used Duolingo quite a bit, and recently learned Spanish to an upper intermediate level. In my opinion, Duolingo is just as weak with pure reading as with spoken language. You'll learn some vocabulary and be introduced to ideas, and that's valuable, but not enough. Just like spoken, to learn to read, you have to read a bunch of stuff you can understand. I jumped straight from Duolingo to children and young adult books, and it was a difficult transition with lots of intensive looking-up-every-other-word study, but, I mean, you do that long enough, and eventually you're just reading.
