how to display osd_cat on a remote HDMI Screen
Open a window on a remote X display (why "Cannot open display")?
scp from remote Linux to local Windows with spaces in local path To push a file from a Linux terminal to a Windows system, the following two examples work just fine.  scp /home/user.name/file.html user.name@local.ip.num:/C:/Users/user.name/test_folder/file.html  scp /home/user.name/file.html user.name@local.ip.num:"/C:/Users/user.name/test_folder/file.html"   I need to do this where the local folder has spaces and I cannot change the name,  say /C:/Users/user.name/test folder/  All of the following fail with the message scp: ambiguous target  scp /home/user.name/file.html user.name@local.ip.num:"/C:/Users/user.name/test folder/file.html"  scp /home/user.name/file.html user.name@local.ip.num:"/C:/Users/user.name/test\ folder/file.html"  scp /home/user.name/file.html user.name@local.ip.num:"'/C:/Users/user.name/test\ folder/file.html'"  scp /home/user.name/file.html user.name@local.ip.num:"/C:/Users/user.name/test\\ folder/file.html"  scp /home/user.name/file.html user.name@local.ip.num:"'/C:/Users/user.name/test\\ folder/file.html'"  scp /home/user.name/file.html user.name@local.ip.num:"/C:/Users/user.name/test\\\ folder/file.html"  scp /home/user.name/file.html user.name@local.ip.num:"'/C:/Users/user.name/test\\\ folder/file.html'"   How do I get this to work? I found a good replacement IDE for Delphi called Lazarus. But I don't have a question for programmers.  Will the statically linked Linux binary work on all Linux distributions? I.e. it does not matter on what Linux distro I built it and it will work on Debian / ArchLinux / Ubuntu / OpenSUSE / ... whatever?  As a result of my findings, does really only matter 32bit vs 64bit? I want to be sure before I publish. Proving the identity $\sum_{k=1}^n {k^3} = \big(\sum_{k=1}^n k\big)^2$ without induction I recently proved that  $$\sum_{k=1}^n k^3 = \left(\sum_{k=1}^n k \right)^2$$  using mathematical induction.  I'm interested if there's an intuitive explanation, or even a combinatorial interpretation of this property. I would also like to see any other proofs. I've seen them maneuver. They definitely can go backwards. How fast can they go in reverse? Is warp speed possible, or is reverse limited to impulse power? If it is limited to impulse power, can they travel backwards under impulse power as fast as they travel forwards under impulse power? For some reasons my brush stroke suddenly looks like this:     As the picture showed, the edges are jagged and pixelated. It doesn't happen before and it's just one of the built-in inking brush.  I know there are a lot of similar questions here but please don't mark this as duplicate. I double checked all the thing the other answers suggested: It's brush tool, not pencil, and my mode of brush and layer is Normal, not Dissolve. It's pixelated even if I draw with mouse so it's not tablet driver issue. I disabled GPU render but nothing changed. How do I fix this? Fresh Windows-10 Install A Windows-7 laptop was upgraded to Windows-10 during the Microsoft free upgrade period when they were nudging users to migrate away from 7 to 10.  The system is sluggish and crash prone: I would like create a fresh install with a new SSD from a Windows 10 install .iso burned to a USB drive.  Is it possible (and how can) the the license-key from the old drive be recovered and migrated to a fresh install?   If this is not the right question to ask, I would appreciate edits to the questions: thank you. In the various Zelda video games, there seems to be a common mythology, and at least some potential to be in the same place. Do the various Zelda games take place in the same world, or is there no intent to do so? Is it possible to speed up the gzip process?  I'm using  mysqldump "$database_name" | gzip &gt; $BACKUP_DIR/$database_name.sql.gz   to backup a database into a directory, $BACKUP_DIR.  the manpage says:     -# --fast --best             Regulate  the  speed  of compression using the             specified digit #, where -1  or  --fast  indi‐             cates  the  fastest  compression  method (less             compression) and -9 or  --best  indicates  the             slowest compression method (best compression).             The default compression level is -6 (that  is,             biased  towards high compression at expense of             speed).    How effective would it be to use --fast? Is this effectively lowering the CPU usage on a modern computer?   My test results  I didn't notice any acceleration:   7 min, 47 seconds (with default ratio -6) 8 min, 36 seconds (with ratio --fast ( = 9 ))   So it seems it takes even longer to use the fast compression?  Only higher compression really slows it down:   11 min, 57 seconds (with ratio --best ( = 1 ))   After getting the Idea with lzop I tested that too and it really is faster:   6 min, 14 seconds with lzop -1 -f -o $BACKUP_DIR/$database_name.sql.lzo $\mbox{rank}(A)=1$ implies $\det(A+I)=\mbox{trace}(A)+1$ This problem comes from exercise from my lecturer  Let $A$ be a square matrix such that $\mbox{rank}(A)=1$. Prove that $\det(A+I)=\mbox{trace}(A)+1$.  ($I$ is the identy matrix)  I usually haven't any idea in solving linear algebra problem.

REML or ML to compare two mixed effects models with differing fixed effects, but with the same random effect? Background:  Note: My data set and R code are included below text I wish to use AIC to compare two mixed effects models generated using the lme4 package in R.  Each model has one fixed effect and one random effect.  The fixed effect differs between models, but the random effect remains the same between models.  I've found that if I use REML=TRUE, model2 has the lower AIC score, but if I use REML=FALSE, model1 has the lower AIC score. Support for using ML: Zuur et al. (2009; p. 122) suggest that &quot;To compare models with nested fixed effects (but with the same random structure), ML estimation must be used and not REML.&quot;  This indicates to me that I ought to use ML since my random effects are the same in both models, but my fixed effects differ.  [Zuur et al. 2009.  Mixed Effect Models and Extensions in Ecology with R.  Springer.] Support for using REML: However, I notice that when I use ML, the residual variance associated with the random effects differs between the two models (model1 = 136.3; model2 = 112.9), but when I use REML, it is the same between models (model1=model2=151.5).  This implies to me that I ought instead to use REML so that the random residual variance remains the same between models with the same random variable. Question: Doesn't it make more sense to use REML than ML for comparisons of models where the fixed effects change and the random effects remain the same?  If not, can you explain why or point me to other literature that explains more? # Model2 &quot;wins&quot; if REML=TRUE: REMLmodel1 = lmer(Response ~ Fixed1 + (1|Random1),data,REML = TRUE) REMLmodel2 = lmer(Response ~ Fixed2 + (1|Random1),data,REML = TRUE) AIC(REMLmodel1,REMLmodel2) summary(REMLmodel1) summary(REMLmodel2)  # Model1 &quot;wins&quot; if REML=FALSE: MLmodel1 = lmer(Response ~ Fixed1 + (1|Random1),data,REML = FALSE) MLmodel2 = lmer(Response ~ Fixed2 + (1|Random1),data,REML = FALSE) AIC(MLmodel1,MLmodel2) summary(MLmodel1) summary(MLmodel2)  Dataset: Response    Fixed1  Fixed2  Random1 5.20    A   A   1 32.50   A   A   1 6.57    A   A   2 24.77   A   B   3 41.69   A   B   3 34.29   A   B   4 1.80    A   B   4 10.00   A   B   5 15.56   A   B   5 4.44    A   C   6 21.65   A   C   6 9.20    A   C   7 4.11    A   C   7 12.52   B   D   8 0.25    B   D   8 27.34   B   D   9 11.54   B   E   10 0.86    B   E   10 0.68    B   E   11 4.00    B   E   11 Would a wormhole be able to move? Display only the penultimate (second last) row of a text When may adjectives precede determiners? (E.g. too difficult a task) The expression too difficult a task sounds a little pompous, but it doesn't sound ungrammatical. According to my folk-beliefs about English grammar, determiners precede adjectives. However, the expression too difficult a task seems to controvert that belief.  Additionally, the expression too difficult of a task seems grammatical too.    Under what conditions may determiners precede adjectives? Are there conditions under which too difficult of a task would be a more grammatical expression than too difficult a task would be?   (This question does not ask what the question “How big of a problem” vs. “how big a problem” asks. That question does not pertain to determiners.) How to reinstall kernels after accidental deletion with a separate boot partition and an encrypted LVM volume? My installation is a Ubuntu 12.04 64 bits (Classic "legacy" MBR - No  EFI/UEFI here) with two partition :   A separate boot partition An encrypted LUKS volume that contains the system Logical Volumes   I seems I accidentaly deleted all the current kernel files with:  sudo apt-get purge 'linux-image-3.8*'    I applied the updates with Ubuntu Software Update, rebooted and then: Ubuntu can't boot.  I tried to boot on a live DVD with a 14.04.1 Ubuntu and can still see my partitions (described later):  /dev/sda1 (boot) /dev/sda2 (Encrypted volume) /dev/sda5 (Logical Volume container)  What are the steps to recover/reinstall the kernel files and dependencies in order to cleanly reboot my installed system?  Thanks in advance Cannot do a `composer install` even though my minimum stability is listed as dev I am trying to build the master branch in my project after updating to 8.5.0, but am being met with an error from composer (which I did not get on my develop branch):     The requested package drupal/focal_point 1.0.0-beta6 is satisfiable by   drupal/focal_point[1.0.0-beta6] but these conflict with your   requirements or minimum-stability.   In my composer file, I have:  "drupal/focal_point": "^1.0",   as well as:  "minimum-stability": "dev",   How can I fix this so TravisCI gets unstuck? It worked fine for the develop branch, and the master is now updated with it. Is there any utility to check whether my laptop battery is in healthy condition or not?
