I'm looking for specific versions of Google Chrome but I cannot find them. I don't want a random site that offers me to download these. It must be safe, preferably of Google itself.  I could find one for Firefox:   I imagine there must be something like that offered by Google for Google Chrome?
I have a specific requirement (probably silly!) for testing a browser of Chrome. I realize this requirement isn't the most logical, but politics being what they may I'd like to know the technical workaround.  I need to test a site in version, let's say, 28 of Google Chrome. Obviously Google runs a silent updater which can be disabled, but at this point they don't (to my knowledge) release old archives of the MSI installers (which I can easily use to reinstall and force a no-update option for testing). If we can get this working on a single instance then there's a possibility that a virtual machine or some other workaround will give us an easy restore point to meet this test.  If anyone has a good idea of where to start here that would be amazing.  I've already floated the "why are we doing this question?" and the answer is that it is part of the requirements so we need to make a best effort.  UPDATE:   FileHippo appears to only archive the online installer (automatic update)  OldApps doesn't archive Chrome anymore  OldVersion doesn't appear to have any Chrome Archives   UPDATE 2:  - The accepted answer's server is the correct solution here at this point in time. Basically speaking you're looking for the full install (30 or so MB). If you have an 800K file it is the online installer which automatically updates.
Pseudoinverse and norm Suppose the m * n matrix A =$ \begin{bmatrix}     A_1 \\A_2 \end{bmatrix}$ where A1 is a nonsingular square matrix (n*n) and A2 is an arbitrary matrix. Why is $||A^{+}||_2 \leq ||A_1^{-1}||_2$  ?   ($A^{+}$ denotes the psuedoinverse) Evaluation of OptionValue[] How does a cell phone charger work? Which is the easiest way to evaluate $\int \limits_{0}^{\pi/2} (\sqrt{\tan x} +\sqrt{\cot x})$? url completion in cartoDB info windows How long was Luke Skywalker's training with Yoda? From the answer to the question  :     We also don't know how much time Luke spent training.   I tried to check some references like  and  related section on their Wookieepedia articles, but there is not even a clue of the amount of time he spent there.  Is there any canon information on the subject? Or any extrapolation of how long Luke's journey on Dagobah was? Was it a day? Several weeks? Some months? Replace symbols with values without evaluation I thought of this question right after I posted a tweet about a service upgrading me to a free student account since I am in college. I said "That really helps a broke college student out." I actually paused for a second while I was writing that to decide if I should say     That really helps out a broke college student.   or     That really helps a broke college student out.   Are there any prescriptive rules about splitting phrasal verbs like this? I know this breaks the "don't put a preposition at the end of a sentence" rule, but that "rule" has an exception for phrasal verbs.  To clarify:   Is there any rule that says phrasal verbs can't be split, even if it is just an imposed, prescriptive rule? Does splitting a phrasal verb to put a preposition at the end of a sentence fall under the phrasal verb exception to the prepositions at the end of a sentence rule? Why would I open a low-rate 9 month CD instead of a higher rate savings account? One specific (popular online) bank is offering a 9 month 1.25% CD, while it's savings account is 1.90%.  There's no way I see interest rates tumbling in the next nine months, so why should I -- why should anyone -- get a 1.25% CD when savings accounts are paying 52% more interest?  (This question is not specific to this particular bank at this particular time.  It's about the general practice of buying low-rate CDs when savings accounts have a higher rate.) Is the Moonbeam spell amazing, or are we doing it wrong? The description of the moonbeam spell (PHB pg. 261) says:  When a creature enters the spell's area for the first time on a turn or starts its turn there, it is engulfed in ghostly flames that cause searing pain... On each of your turns after you cast this spell, you can use an action to move the beam 60 feet in any direction.  We read this to mean a creature takes damage from moonbeam when any of the following conditions are met:  It begins its turn inside the moonbeam It enters the moonbeam on its turn The creature finds itself inside the beam on another character's turn, no matter how it got there  The creature will not take damage in the following instances:  A creature moves from one part of the beam to another (obviously it had to take damage, but it won't take more damage) A creature is in the beam after having been inside the beam already on that turn.  Following these assumptions, our druid cast a moonbeam and did damage to two enemies, Bob and Frank. On their turn, they took damage again, killing Bob. Frank left the beam. On the druid's next turn, she moved the beam in a circular motion, not exceeding 60 total feet of movement, and in the process the beam came in contact with a dozen enemies and ended on Frank. All dozen enemies received damage, as they were inside the beam at some point during the turn. On Frank's next turn, he again took damage for the fourth time and died. On each of the druid's turns, she moved the moonbeam around like this until the fight ended (it did not exceed the time limit and she made all concentration checks). Is this a legitimate use of moonbeam? It seems awfully powerful for a level 2 spell. "Within" and "in" when referring to time I know that both can mean "inside" but what I don't have clear is whether both mean the same when talking about time. For example:   The party is in two days = The party is within two days ??   According to this link  within means a limit that can be exceeded, so I'm wondering too if say "the party is within two days max" is correct or redundant. What is the pythonic way to avoid default parameters that are empty lists? Sometimes it seems natural to have a default parameter which is an empty list. Yet . If for example, I have a function: def my_func(working_list=[]):     working_list.append(&quot;a&quot;)     print(working_list)  The first time it is called the default will work, but calls after that will update the existing list (with one &quot;a&quot; each call) and print the updated version. So, what is the pythonic way to get the behavior I desire (a fresh list on each call)? The third formula on the  states that $$\varphi (mn) = \varphi (m) \varphi (n) \cdot \dfrac{d}{\varphi (d)} $$ where $d = \gcd(m,n)$.  How is this claim justified?  Would we have to use the Chinese Remainder Theorem, as they suggest for proving that $\varphi$ is multiplicative? I know I can become root (super user) via the su command but I have to authorize it after entering the commands. Is there a way I can become root and authorize (with password) in one line Did Tyrion even have the authority to do this? In Game of Thrones S08E04 (The Last of the Starks) when Tyrion and Jaime are confronted by Bronn, Tyrion attempts to evade poetic justice by offering Bronn Highgarden. Was it even within Tyrion's power to give away Highgarden?    Follow up question: Why would Bronn even risk waiting around to see how things play out? Based on his demeanor during that conversation, he seemed pretty pissed that all he has to show for serving the Lannisters is a lousy title. So, why wouldn't he just take bird in hand and collect the reward from Cersei instead of risking Tyrion dying before all of this is over? I mean, Tyrion even mentioned to him that all of this means nothing until they [the North] take over King's Landing, but it didn't really seem to faze Bronn. Practical uses for the "internal" keyword in C# Could you please explain what the practical usage is for the internal keyword in C#?  I know that the internal modifier limits access to the current assembly, but when and in which circumstance should I use it? What is the reasoning behind limiting "recidivists" to post one question per week? currently restricts recreated accounts to "posting only one question per week..."  I would like to understand why this rate was picked, and not, say, once a day or once a month?  The reason why I ask is that some users limited or banned at Stack Overflow . I expect that learning more about the limitation would help me better understand its impact on Programmers. Probability that 2 appears at an earlier position than any other even number in a permutation of 1-20 Suppose we uniformly and randomly select a permutation from the 20! Permutations of 1,2,3,...,20. What is the probability that 2 appears at an earlier position than any other even number in the selected permutation?  My approach :   2 in first position ==> 1*19! (1 is the position of 2)  2 in second position ==> 10 *1 *18!  2 in third position ==> 10*9 *1 *17!  . . .  2 in 11th position ==> 10*9*8*7*6*5*4*3*2*1*1*9!  But this was asked as a multiple choice question in GATE 2007 and the options were  (A) 1/2   (B) 1/10  (C) 9!/20!  (D) None of these  I am not able to reduce this analysis to a given option. Can I get smaller tires without changing my rims? I currently ride a hybrid that came with 700x32c tires. Can I swap out a narrower tire without changing the rims, or do rims only fit a specific size of tire?   How small can I go before I have to buy new rims?  I hear having narrower tires makes you go quite a bit faster.  Does it really help that much? UTF8 to/from wide char conversion in STL Is it possible to convert UTF8 string in a std::string to std::wstring and vice versa in a platform independent manner? In a Windows application I would use MultiByteToWideChar and WideCharToMultiByte. However, the code is compiled for multiple OSes and I'm limited to standard C++ library.
