My computer died. One day it worked fine, the next it didn't power up. They told me the motherboard has died.  I don't have any backups. They recovered all the data from C: drive, however, all my online passwords were stored in Chrome. Is there a way for me to recover them?  The computer that died had Win10 and now I'm using my old one with Win7. If there was a file, from which Chrome could recover the passwords, where could I find it?
Now that I have Google Chrome all set up, I got myself a new laptop. Does anyone have any idea how to transfer my settings, cookies, favorites, etc?   I checked documents and settings\me\application data, and found nothing.
What's the origin of "I'm down with it"? I understand it's an expression of agreement. What exactly does it mean and where did it originate from? How can I diagnose and repair missing drive space? I have a small ext3 / partition on a 2T drive which appears to have a discrepancy in its free space. How can I determine what is causing it and how it can be fixed.   After trying everything I could think of, I forced a fsck on boot which didn't have any affect.  I have other systems configured identically which don't exhibit this condition.  # df -h / Filesystem            Size  Used Avail Use% Mounted on /dev/sda1             9.7G  8.9G  318M  97% /  # du -shx --max-depth 1 / 5.2G    /  # lsof | awk 'BEGIN {t=0} /(deleted)/ {t+=$7} END {print t}' 0  # tune4fs -l /dev/sda1 | grep -E 'state|Free|Reserve|size|Inode' Filesystem features:      has_journal ext_attr resize_inode dir_index filetype needs_recovery sparse_super large_file Filesystem state:         clean Inode count:              2621440 Reserved block count:     131029 Free blocks:              212317 Free inodes:              2487281 Block size:               4096 Fragment size:            4096 Reserved GDT blocks:      639 Inodes per group:         32768 Inode blocks per group:   1024 Reserved blocks uid:      0 (user root) Reserved blocks gid:      0 (group root) Inode size:               128   Edit:  fsck says the partition is 2% non-contiguous.

Before I even thought to approve the edit, I went to close it as a duplicate (as it was), but the suggested edit was still there.  If the question is being closed anyways (as a duplicate or otherwise) do I reject or approve the suggested edit? What is the proper etiquette? Can't delete files or folders on partition I have an NTFS partition. The idea is I can use this for data on either Ubuntu Mate or Windows 10 dual boot. It worked fine when I first installed Mate, but recently I no longer have the delete option when I right-click on a file or folder. The delete key does nothing. I also can't paste into the partition (Paste greyed out). It's as if the whole partition is read-only. In Gparted, the partition is marked with a key. Does this mean anything? I'm not aware of having changed anything, however, Windows recently did a big update - have they hijacked my drive?  I've read related posts, but people speak of returned errors - I have no errors, just nothing happens. Also, suggested solutions seem far too technical for what must surely be a simple tick-a-box fix!  Please note - for me the Terminal is where I get off a train and Sudo sounds like a Japanese noodle dish. ;) GUI's preferred if possible! Thanks for your patient help! I have a huge text file (~1GB) and sadly the text editor I use won't read such a large file.  However, if I can just split it into two or three parts I'll be fine, so, as an exercise I wanted to write a program in python to do it.    What I think I want the program to do is to find the size of a file, divide that number into parts, and for each part, read up to that point in chunks, writing to a filename.nnn output file, then read up-to the next line-break and write that, then close the output file, etc.  Obviously the last output file just copies to the end of the input file.  Can you help me with the key filesystem related parts: filesize, reading and writing in chunks and reading to a line-break?  I'll be writing this code test-first, so there's no need to give me a complete answer, unless its a one-liner ;-) What is the difference between class and instance attributes? Is there any meaningful distinction between:  class A(object):     foo = 5   # some default value   vs.  class B(object):     def __init__(self, foo=5):         self.foo = foo   If you're creating a lot of instances, is there any difference in performance or space requirements for the two styles? When you read the code, do you consider the meaning of the two styles to be significantly different? What's the difference between an argument and a parameter? When verbally talking about methods, I'm never sure whether to use the word argument or parameter or something else. Either way the other people know what I mean, but what's correct, and what's the history of the terms?  I'm a C# programmer, but I also wonder whether people use different terms in different languages.  For the record I'm self-taught without a background in Computer Science. (Please don't tell me to read  because I'm asking this for the benefit of other people who don't already have a copy of 's marvellous book.)  Summary  The general consensus seems to be that it's OK to use these terms interchangeably in a team environment. Except perhaps when you're defining the precise terminology; then you can also use "formal argument/parameter" and "actual argument/parameter" to disambiguate. Why are Grothendieck's and Hartshorne's definitions of quasi-coherence equivalent? Hartshorne's Algebraic Geometry defines an $\mathcal O_X$-module $\mathscr F$ to be quasi-coherent if there is an open affine cover $(U_i=\operatorname{Spec} A_i)_{i\in\mathcal I}$ of $X$ such that each $\mathscr F\rvert_{U_i}$ is isomorphic to the sheaf of modules $\widetilde{M_i}$ associated to some $A_i$-module $M_i$. It is later proved that this is equivalent to the statement that for any open affine $U=\operatorname{Spec} A\subseteq X$, there exists an $A$-module $M$ with $\mathscr F\rvert_U\cong\widetilde M$.  On the other hand, Grothendieck's Éléments de Géométrie Algébrique defines $\mathscr F$ to be quasi-coherent if every point $x\in X$ admits an open neighborhood $U\subseteq X$ such that $\mathscr F\rvert_U$ is isomorphic to the cokernel of a morphism of free $\mathcal O_U$-modules.  Now I wonder how those definitions are equal. I tried proving it by myself, but both directions seem quite nontrivial to me... Any hints? Is there any difference between Present Perfect and Present Perfect Continuous? Do I need to upgrade RAM from 4GB to 8GB for Android development? I'm an android developer and have laptop with 4GB RAM. When I compile my project the RAM is used at 100%.    If I add more RAM will it solve the problem? What is the difference between logistic regression and Fractional response regression? As far as I know, the difference between logistic model and fractional response model (frm) is that the dependent variable (Y) in which frm is [0,1], but logistic is {0, 1}. Further, frm uses the quasi-likelihood estimator to determine its parameters. Normally, we can use glm to obtain the logistic models by glm(y ~ x1+x2, data = dat, family = binomial(logit)). For frm, we change family = binomial(logit) to family = quasibinomial(logit). I noticed we can also use family = binomial(logit) to obtain frm's parameter since it gives the same estimated values. See the following example library(foreign) mydata &lt;- read.dta(&quot;k401.dta&quot;)   glm.bin &lt;- glm(prate ~ mrate + age + sole + totemp,                 data = mydata, family = binomial('logit')) summary(glm.bin)  return,  Call: glm(formula = prate ~ mrate + age + sole + totemp,      family = binomial(&quot;logit&quot;),      data = mydata)  Deviance Residuals:      Min       1Q   Median       3Q      Max   -3.1214  -0.1979   0.2059   0.4486   0.9146    Coefficients:               Estimate Std.

However, to obtain the correct SE, we have to use `library(sandwich)` as in this [post][1].  Now, my questions:  1. What is the difference between these two codes? 2. Is frm about to obtain robust SE?  If my understanding is not correct, please give some suggestions.

Stop setInterval call in JavaScript I am using setInterval(fname, 10000); to call a function every 10 seconds in JavaScript. Is it possible to stop calling it on some event?   I want the user to be able to stop the repeated refresh of data. What is the use of the Dot Product of two vectors? The shrine indicator (shrine detector? GPShrine?) has both visual and audio cues, so when I'm near a shrine, it beeps constantly. Unfortunately, I occasionally play the game near other humans who are engaged in their own activities, and my wife is decidedly unimpressed with this feature.   When I got the shrine indicator, I could have sworn that the dialogue said I could press [Y] to disable it... but pressing Y pulls out my weapon.   Ideally, I'd like to just make it stop beeping, but stay on for visual cues. But I'll settle for being able to turn it off entirely at times. Is it appropriate to down-vote posts containing SQL injection vulnerabilities? Mounting filesystem with special user id set Setting constraints causes the location of the constrained objects/bodies not be accessible I set up 2 bodies manually &amp; assigned Copy Location constraint to one with respect to another body. Then I set up the keyframe for the guiding body &amp; then I started to view the change in the location of the constrained body. What I noticed in the 3D viewport was the constrained object moves, but when I look into its real position the values are stagnant. Why is that? I was unable to find my answer in previously asked questions by other people !!
