How do I launder cotton clothes or like towels without ruining the texture of them? The laundry machines in my apt complex have options for Whites, Colors, and two I don't remember, while the dryers have Whites/Colors, Permanent Press, and Delicates. I have tried fabric softener, it did not lessen the impact of these terrible beasts on my clothing.

photomikey posted:My waffle iron was purchased in the late 90s for ~$20 and has served me well over 20 years, but it's a pain in the rear end to clean, and frankly, I'd like to make waffles more often, and not with something that says "do not submerge" on it. I have an older George Foreman grill with removable plates that has a pair of waffle plates. It makes great waffles and since the plates are removable they go easily into the dishwasher. There is also the bonus that you can use it for otehr things too. It's not just an appliance for 1 specific thing.

I remember seeing some "fact" that was like it would take 20 years to heat a cup of coffee by yelling at it. Is that actually possible? Or is the real science behind it that it would take 20 years to "add up" to the amount of energy required? Or could continuous yelling or noise actually heat something over that long of a time span? Might have to start screaming at my coffee if so

It's not actually possible, as the added heat would dissipate much faster than you're adding more. You'd need a perfectly insulated cup of coffee (literally impossible) and some way to import your shouts into its perfectly insulated environment. That "fact" is probably based on the acoustic energy in a shout, and to put that amount of energy into relateable terms, someone calculated how much shouting would be needed to raise the water 80 C or whatever. In other words, it's probably true but they failed to mention (or you failed to remember) the stipulation of "if you had perfect insulation."

There are other effects to be concerned about as well. Bonus question: I have two columns of data in Excel that need work, and I haven't the slightest idea how to do it. Each row was generated when a simulated particle crosses a specific barrier in a numerical simulation, and there are countless duplicates (this is okay). Column A contains the particle number, column B contains data about the particle. What I'm trying to do is this: I need all rows whose particle number (column A value) matches particles with a column B value above a set threshold. The way I would want to do it is sort by column B value, then apply a filter that says "Column A equal to A1-A5985". (Yes, there are almost 6000 particles above that threshold.) I'm open to using a different program to do this if it would be faster. I'm just using Excel because it's installed on this computer.

In sorting by column B value, column A's values are no longer numerically sorted. They range from 1 to almost 90,000, in essentially random ordering.

Each row was generated when a simulated particle crosses a specific barrier in a numerical simulation, and there are countless duplicates (this is okay). Column A contains the particle number, column B contains data about the particle. Here comes awk to save the day. If you're on Mac or Linux or other unixy goodness, this will just work as written. If you're on Windows, awk for Windows exists, so you'll have to install that first. Save your excel spreadsheet as a .csv file, get to a command line, change to the directory where your csv file is, and then run: code:e: Quick translation into English. Awk is a language that's optimized for doing things to long text files, like a CSV file, which is just a plain text version of a spreadsheet with each row on one line and the columns separated by commas (hence Comma-Separated-Value, or csv). Awk will run the commands in the main block of {} braces for each line in the input file. The "-F ," part tells it that the fields on each line are separated by commas instead of the default spaces. $2 just means the second field on the line, and NR means the number of the current line being worked on. So it goes through each line in your csv file, and if the second field (i.e. the second column on your spreadsheet) is bigger than the threshold (in this case 40), it'll print out the line number. Then instead of displaying the result on the screen, it dumps it all into an output file because from the sound of it there may be thousands of these.

You can bang it out pretty quickly with a nested IF in column C =if(A1=="nameofparticle", if(B1 > #, 1, 0), 0) Or something like that. I'm on my phone. Then sort C There's probably a better way, but that should get you there in a hurry.

Thanks for the pointer to AWK and for the explanation of the command. Does essentially what I thought it did, which isn't quite what I need. I need all rows associated with particles that have even a single row with column B data above the threshold. (This command looks like it will give me the just the line numbers where the threshold is exceeded.) KnifeWrench posted:You can bang it out pretty quickly with a nested IF in column C Same here.

(This command looks like it will give me the just the line numbers where the threshold is exceeded.) Aha, that's slightly more complex. Try: awk -F , '{if ($2 > 40) {foo[$1]++;} } END {for (i in foo){print i;} }' particles.csv > temp.txt; awk -F , 'BEGIN {while (getline < "temp.txt") {foo[i] = $0; i++;}} {for (i in foo) {if (foo[i] == $1) {print NR;}} }' particles.csv > output.txt The first awk builds an associative array of all particle numbers that are above the threshold (40 here), and in the END block dumps them out to a temp file. The second awk reads in that list of particle numbers in the BEGIN block, then for each line in your particles.csv file, it looks through the list, and if there's a match, it prints out the current line number.

Grundulum posted:
=IF( ISNUMBER( MATCH(A*,$B$2:$B$5986,0) ) ,1,0) So your A value has to match any B value over the a specific value? If that's the case you can use your if statement to return the A value (instead of 1), then filter the column to remove the 0's, and filter B to be above your value.

I sorted by column B value so that I had all B values above the threshold at the top. The line I presented looks for A values that match A values at the top of the list (i.e., those particles whose B values exceeded the threshold).

So there are duplicate A values and you want to keep all of them as long as one of their B values is above the threshold? If you use your current if statement you can still filter the rows in excel rather than exporting to awk and then back in: Select all the columns, filter, then uncheck 0 in the drop down box.

True (and again), but this reduces the number of rows down to just 33,000 or so, a much more manageable number than the original 400,000 rows. That's how I'll rationalize it.

I have a chest freezer in my garage. It's relatively full. I live in San Diego where outside temperatures are temporate all year long. In the event of a long term power outage, how long until all of this food thaws and goes above a safe handling temperature?

In the event of a long term power outage, how long until all of this food thaws and goes above a safe handling temperature? Googling suggests 24 hours or so, as long as (1) the freezer is not opened at all during the outage, (2) the outside temperature isn't much above 85*F, and (3) the freezer was functioning properly before the outage. Sources also say you should leave the freezer closed for 24 hours after power comes back on, to allow the food in the freezer to thoroughly refreeze.

I'm trying to figure out how long I could survive on freezer food in the event of a power outage, natural disaster style. It is hard for me to believe that all the food in my freezer, which is frozen solid, will be bad in 24 hours. Maybe not frozen solid anymore, but certainly cold enough to not go bad. I was thinking 4-5 days?

There is a lot of good disaster preparedness advice available on Ready.gov. Remember if you stock up on food to rotate your supply regularly. You don't want to get nailed by a hurricane and find out that all your emergency food is five years old. Rent-A-Cop fucked around with this message at 05:49 on Jul 15, 2014 |

Serious guys? If you have a decent, well-insulated chest freezer, put a weight on top to keep a good seal, and it's jam-packed, not in direct sunlight, and your house isn't hot, and you don't open the thing, then it'll last more than a week before everything has melted to the point of being above refrigerator temps. This is from personal experience, not a website that's talking about the freezer part of your fridge.

This is from personal experience, not a website that's talking about the freezer part of your fridge. We actually had a power outage that lasted twelve hours a few years back, and before I went to bed I had a bowl of cereal and the milk was still cold. This is in a stand-up fridge that was only fridge temp to begin with. If the food can last five days... I'm not really shooting for much more than five days to begin with. If I can't get out in five days... I'm not sure there's much left to live for.

If you don't refreeze it when the power comes back on and only open the door once a day to get the entire days food out at one time you'll still have good food after a week minimum. Wrapping the freezer in blankets and any other improvised insulation will extend this a day or so easily.

That sounds like a problem on your end since it works just fine for me. The star turns yellow and thread is bookmarked. that's what it should look like. Have you tried with a different browser or something?And another excel question, there seem to be some ridiculously good people in here for those. I copy a large batch of stuff from a economics program with both both text and numbers in a bunch of cells. Most of it is fine but some of the number cells are text instead of numbers, according to excel. If i type the number in manually it works fine. An example is the number 10 468,24 which excel reads as text. If I remove the space from that and make it into 10468,24 it is read as a number. Is there a setting somewhere or something I'm missing that will make excel just read it as numbers from the start? I can just use Find and Replace to replace all spaces with nothing but I would prefer a solution over a workaround if there is one.
