There seems to be a number of discrepancies in the power of Mjolnir in the MCU.  In Thor Odin places the power of Thor into his hammer Mjolnir proclaiming:     he who wields the hammer, if he be worthy will have the power of Thor.   At the climax of the film we see Thor regain his powers and armour when he sacrifices himself for the town.   In Avengers: Age of Ultron this is reaffirmed when the Avengers try to lift the hammer with only Cap getting close.   In Thor: Ragnarok Mjolnir is destroyed and Thor then discovers the powers where inside him all along.    But in Avengers: Endgame     Captain America wields Mjolnir gaining the power of Thor.   However, we saw in Thor: Ragnarok that the hammer has no real power of its own, the power was inside Thor all along. In addition Mjolnir being destroyed doesn't affect Thor's strength and when he gets Stormbreaker he becomes more powerful suggesting that Stormbreaker also gives the power of Thor to the wielder.   So does Mjolnir give additional powers and allow the bearer to have the powers of Thor, or is it just a magic hammer that has special powers all of its own?
We learned in Thor: Ragnarok that Mjolnir is only a focus for Thor's power, not the source. If so, when a worthy​ being lifts Mjolnir and gains "the power of Thor", where are they getting the power from?
How to loop over the lines of a file? I installed Ubuntu 18.04, and I want to customize the fonts. I have already change all the setting by tweak tool. But the system default font not be changed, is anything I need to do? Unable to login to account in ubuntu 18.04 vmware workstation 15, after update I installed the latest updates from the software update center today (I update when ubuntu displays a notification), restarted the machine and now it's unable to boot properly. The best screen I can get is displayed below. If I resize the screen then it goes to black. If I restart the machine then it displays just purple.    Note that the screen is unresponsive, I can't click anything on it.  Other than SMBus Host Controller not enabled! I don't see any other warnings. Note that I don't know if this warning existed before the update.  I'm running ubuntu 18.04 in vwmare workstation 15 player (latest update). Any ideas on how to begin debugging this?    Update: Trying to boot Ubuntu, with Linux 4.15.0-50-generic instead of Ubuntu, with Linux 4.15.0-51-generic didn't help.  Update: Blacklisting i2c-piix4 according to  answer didn't remove the warning or fix the issue.  Update: Blacklisting i2c-piix4 according to  answer removed the warning but didn't fix the issue.  Update: The answer from Uzair helped me log into the account (run dpkg and update grub from recovery mode).  Answer:  answer helped me fully to resolve the issue. I don't understand the fix. If anyone does, put it as the answer and I'll mark it as such.  Regarding duplicity: The answer from another question did solve my issue but I don't think my question is a duplicate of that one. I began with a fresh install of 18.04 a few months ago, did several updates without an issue and only today experienced issues which are different than those described in the other question. I think we experienced different bugs with wayland and we both solved it by disabling it which is a destructive solution applicable to many questions. I believe that umask is something that controls , but do not fully understand it.  After running umask 0644 in a , I cannot read the files I create with the command-line text editor nano. I noticed that the permissions of that file are set to 0022 instead of the default 0755.  How does umask work? I thought I could just remove the each digit in the umask from 0777, 7 - 6 = 1 and 7 - 4 = 3, so I expect the permissions to be 0133, but apparently, this is not the case.   What is umask exactly? Explain it to me like I was a "Linux noob" How do I calculate with umask? What are use cases for umask? What’s the real-world origin of the name Azor Ahai? Azor Ahai is some mythical hero, who may or may not coincide with other mythical heros that are supposed to be born and save us from the eternal night (which is dark and full of terrors, if we are to believe Melisandre).  But I'm interested in the origins of the name, here, in our world. More specifically because in Hebrew "Azor Ahai" means (albeit ungrammatically) "Help my brothers", or if you transliterate it differently you'd get "The Living Help".   Since writers often take meaningful names to be terms from other languages (and mangle them a bit), I can't help but wonder Did GRRM reveal the origin of the name "Azor Ahai" at some point? I read on  that Ubuntu will no longer use the familiar file size units we all know by now (kB, MB, GB, TB) and switch to a different IEC standard (KiB, MiB, GiB, TiB). If this is true, I would like to know what's the reasoning behind this change, and the impact (if any) this change has, especially with multiplatform applications or applications run with Wine. Why does my shell script choke on whitespace or other special characters? How to identify "deictic center" for distinguishing "come" & "go"? Read this paragraph from this    My question is:  How to identify "deictic center" for distinguishing "come" &amp; "go"?  Let say I am at home &amp; I say "I am going to the zoo this evening", so the "deictic center" in this case is my home &amp; I move away my "deictic center".  But let say my friend Tom &amp; I currently at my home &amp; Tom said "Are you Coming to the zoo to see the lion?" &amp; I said "Ok, I am coming to the zoo this evening". So, the "deictic center" in this case is "the zoo" &amp; we move towards the "deictic center" (ie the zoo).  It feels like it is very arbitrary.  Note: See this , it said the selection of "deictic center" could be due to sympathy &amp; politeness. So basically in SQL Server a NULL means there is no value and thus can't be compared which returns some unexpected results.  For example, the following query doesn't return rows where value IS NULL but I want it to:  SELECT * FROM table WHERE   (value != 26)   AND date IS NULL   AND last_modified &gt;= '5/21/2014'   I understand I can do the following as a workaround but seriously? Having to add parentheses and check if is null for every single field every single time I want to include it? Seems ugly, not intuitive and crazy.  SELECT * FROM table WHERE   (value != 26 OR value is null)   AND date IS NULL   AND last_modified &gt;= '5/21/2014'   I mean I know NULL is not a value and thus can't be compared but can't you infer that it is, in fact, definitely not 26? If 26 is something and NULL is nothing and nothing is not something then NULL is not 26. Seems logical to me.  Does anyone know how I can, in a cleaner way, include nulls in my results when using comparisons without having to include an explicit check each and every time. Also turning off nulls on my tables is definitely not an option.  Edit:  My real problem of why I don't want to do it the way I showed was not exposed. So here goes. I am writing a program that let's you build queries to database tables and let's the user dynamically create filters and such which essentially at the end of the day constructs a SQL statement and gets the results to display to the user. The fields chosen by the user can be any and/or all fields in a given database and if I have to literally put that ISNULL check on every single field that would be really inefficient and make looking at the SQL super ugly. My program is table-definition-agnostic meaning I don't care what's in your table and don't want to know what your table's definition is. I just want you to pick a table, choose some fields to filter on with equals, not equals, in, not in, etc ... and then click a button to view the results of that request. Tracking down where disk space has gone on Linux? When administering Linux systems I often find myself struggling to track down the culprit after a partition goes full. I normally use du / | sort -nr but on a large filesystem this takes a long time before any results are returned.  Also, this is usually successful in highlighting the worst offender but I've often found myself resorting to du without the sort in more subtle cases and then had to trawl through the output.  I'd prefer a command line solution which relies on standard Linux commands since I have to administer quite a few systems and installing new software is a hassle (especially when out of disk space!) MBR recovery - Corrupted MBR after it changed to dynamic & testdisk gives up . No backup sector found I had a Windows 7 installation on my 1TB SSD laptop with 4 primary partitions. I wanted to install Lubuntu Linux but the process failed with an error which kind of said:     cannot write MBR   It gave me an option to put an MBR somewhere else or to boot without MBR. None of these options worked and it became a useless install. After this failed dual boot attempt, Windows would give a BSOD wit Code 007 ending - translated to inaccessible boot device. That is a huge NTFS partition and I don't think I have any other media to back it up before formatting it.  My only option is somehow rebuilding the old MBR. Hence I started creating a whole bunch of live USB boot environments  including Super GRUB Disk and MiniTool Partition Editor Live CD, but none of this could ever help me recover my lost MBR.  Win PE 4.0 reported the partition as bad disc and the latest version did not even have an option for MBR. I managed to create a live USB with Testdisk Running on Ubuntu. Whatever partition was seen as HPFS on quick  search was written in the MBR and after this the disc is totally unreadable. Earlier I could see my data through Linux and now I can see nothing.  Here are my questions:   When some data could be read (but Windows would not boot) the MBR was shown as dynamic MBR. As far as I know dynamic MBR is a Windows concept and my Linux attempt would not have converted it. While installing Linux I tried to delete 2 primary partitions which I found to be not really useful (I backed up their data first). So I am not sure what created the dynamic MBR.  Did my dual install convert those basic MBR to dynamic MBR? How did that happen? Here is a screenshot of my deep search attempt with TestDisk which is still in progress. I can see 4 NTFS partitions and one of these two system partitions should be the original MBR. When I tried to write both these system partitions (after stopping the deep search momentarily) I got an error like "partition not found". The file system utility showed me that there is no backup sector and that may be the reason why it cannot be read.  What other Resorts do I have, other than doing a plain format and then using some recovery tool to recover all my lost data? I am not even sure I will recover the folder names.  What other options should I be trying to restore my old MBR so Windows can boot?      Update  as of last I managed to create a live USB w/ W7  I used AOMEI Partition assistant 6.0 and on deeper  search I can see the 909 gb partition - it wont let me select it for recovery. I am sorry if my earlier Q was not clear. I referred to restoring an MBR from a partition . What happened earlier  - superficial search revealed all old partitions but NOT this one   and the later partitions showed up on Deep search &amp; I can select Other partitions for recovery but for this one. It wont let me select the partition I want  Here are some more screen shots    So in summary all that happened is   4 primary windows 7 partition -->  wanted to install Linux so I deleted 2 non bootable partitions after backing them up  ended up with BSOD ( inaccessible boot device ) and noticed that some windows partitions showed up as Dynamic MBR  (using Live USB Linux,gparted )  Use standard testdisk procedure to write MBR from the superficial NTFS-HDFS partition.  this is where I screwed up . Hindsight I should have really done a deep search and caught the 901gb partition to write MBR. I am not sure if I can undo this action  after this - life gets worse. I am  on a ventilator ! Now C is unreadable by windows and linux both and testdisk cannot list file ( see screenshots ) and I have been using a series of live USB's with some recovery s/w but no luck. ALL I want is to recreate that 901gb partition and the boot partition and put the MBR on the latter so I can get my windows 7 back again How to detect Safari, Chrome, IE, Firefox and Opera browser? I am installing Ubuntu 16.04 in an Intel NUC computer with UEFI enabled. I am using an SSD from another computer. During the installation I chose Erase the disk and make a new full install  At the end of the process I see:  grub-efi-amd64-signed failed installation /target/ Ubuntu 16.04    And the system does not boot.  I tried to use boot-repair but apparently it does not solve the problem. Does there exist an automorphism of $\mathbb{C}$ that does not keep $\mathbb{R}$ fixed? (I'm aware of  but it has no answers…)  Let be $u_0 \in \mathbb{R}$ and the sequence $(u_n)_n$ defined by: $u_{n + 1} = \frac12 \arctan(u_n)$.  I define also: $v_n = 2^n u_n$, so I can show that: $\lim (u_n)_n = 0$ (by studying $x \mapsto \frac12 \arctan(x)$), thus, I can show that $(v_n)_n$ is monotone and converges because it is bound.  Now, I conclude: $u_n \sim \dfrac{l}{2^n}$, I'd like to determine $l$ more precisely.  Here is what I tried, I suspect $l$ to be something like $f(\pi)$ for some $f$ :   push the asymptotic expansion of $\arctan$ to the 2nd order and reinject it ; use $\arctan(u_n) + \arctan(1/u_n) = \dfrac{\pi}{2}$ ; use series techniques to look for $\sum v_{n + 1} - v_n$, maybe conclude using Cesaro summation Below is the text in the file:  Pseudo name=Apple Code=42B state=fault  Pseudo name=Prance Code=43B state=good   I need to grep for "42B" and get the output from the above text like:   Pseudo name=Apple Code=42B state=fault   Does anyone have idea on how to achieve this using grep/awk/sed? Evaluate: $\lim_{n\to\infty}\left({2\sqrt n}-\sum_{k=1}^n\frac1{\sqrt k}\right)$ I did a fresh install of trusty 14.04, but a lot of icons are missing. I installed from DVD which was painfully slow and I hope to avoid repeating the process, especially since I started customizing stuff.  Here's my settings window:    I've tried:  sudo apt-get install --reinstall gnome-control-center sudo apt-get install --reinstall gnome-settings-daemon-schemas   None of which changed anything.  Any idea? I wanna edit preferences and none of them are in System Settings, neither in Unity Dash. Image with axis The bar at the very bottom of the screen has gone away?
