I am unable to see the icons in search. I tried sudo apt update, sudo apt upgrade. Logged off, Logged back in, rebooted the system. Still I am unable to see icons when I am searching. How can we resolve this? Thank you very much. :) When I go in the application section, I am able to see the icons.  But when I search with name, nothing shows up.
I did an upgrade today to the latest version of ubuntu. Everything looked good and fine only for me to discover that I cannot find my applications after clicking the 'Show Applications' icon. The same applies when I search for an application in the search bar, I do not see it. It shows me an endless search.  These are the screenshot images of the problem:      In the meantime, I access my applications from the menu at the top bar and also use the terminal to run applications with CLI.
I would like to update a large number of C++ source files with an extra include directive before any existing #includes. For this sort of task, I normally use a small bash script with sed to re-write the file.   How do I get sed to replace just the first occurrence of a string in a file rather than replacing every occurrence?  If I use  sed s/#include/#include "newfile.h"\n#include/   it replaces all #includes.   Alternative suggestions to achieve the same thing are also welcome. Weight Painting Won't Get Rid of Weird Protrusions Tags on badge question list I'm trying to get the Weed-Eater hat on Stack Overflow. To do so, I'm looking at the list of questions . The problem is, no tags show up there, and so it's rather difficult to see which ones I have a shot at. Any chance of showing the tags on this page?  I realize that getting this before Winter Bash is over would be difficult, but it would be good to keep such things in mind for the future. Is there any method to close connection similar to  for  in WordPress?  Is it not necessary to close connection for global $wpdb? Missing settings in GNOME control center installed in Ubuntu MATE I installed GNOME Control Center following  to access Google Drive in Ubuntu MATE 16.04 LTS (MATE desktop environment 1.12.1)   The problem is GNOME Control Center is only showing language support, printers, firewall setup and backups... not online accounts or other settings.  This is what I get:  ~$ gnome-control-center gnome-online-accounts   ** (gnome-control-center:5744): WARNING **: Ignoring launcher landscape-client-settings (missing desktop file)  ** (gnome-control-center:5744): WARNING **: Invalid categories System;Settings; for panel software-properties-gtk.desktop  ** (gnome-control-center:5744): WARNING **: Ignoring launcher ubuntuone-installer (missing desktop file)  ** (gnome-control-center:5744): WARNING **: Could not find settings panel "gnome-online-accounts"   Any ideas?  Thanks! How to dismiss the Windows 8.1 Upgrade banner? As of today, my Windows 8 system is displaying a large banner covering about a quarter of the screen, demanding that I upgrade to Windows 8.1 for free.  The banner helpfully informs me that that I can continue to use the computer while the upgrade is downloading.  There's a button to go to the store for the upgrade, but no other choices, such as No Thanks, Maybe Later, or Absolutely Not.    I can't find a way to dismiss the banner, and I can start programs but can't give them focus while the banner is present.  So I'm dead in the water.  How can I fix this?  Bringing up Task Manager doesn't give me any options.    My employer doesn't yet support Windows 8.1 (which is also an issue, but beyond my control) so I won't be able to connect to work if install the upgrade.  So there is no way on God's green earth that I'm going to install this upgrade now.    UPDATE: The banner went away after the second restart and I was able to run regedit as @magicandre suggested.  The banner hasn't reappeared.  So far, so good. How do I set Titanfall in-game language to English (Russian version)? This question was initially about Russian PC version of Titanfall, available in Russian Origin store.  It appears that there exists a Worldwide PC version of Titanfall for which .  Tech support said that Russian users can only buy Russian version of Titanfall (both normal and Deluxe editions) and that they will not have any other in-game language available. They also offered me a refund, which I accepted.    I'm living in Russia and I recently pre-purchased Titanfall from here. My version doesn't have an option to select game language other than Russian.  Russian version has awful localization, many mistranslated technicalities and poorer game UI fonts than its English counterpart. Titan's on-board AI voice is pretty lame. The campaign briefing lines are cut off to fit the English files' length. Voice actors took liberty to change a few things to their liking. Audio effects like reverberation, echo and such are distinctively more basic. Overall audio quality is much lower, which greatly hinders immersion.  When I was playing open beta, it was all in English and considerably better. The game also doesn't support Russian characters so everyone is using transliteration in chat.  Switching Origin UI language to English didn't change the game's language. It's still all Russian.  How do I change Titanfall UI and audio to English?    Also: the support person didn't explicitly say tampering with localization files was against any rules or policy, so this may or may not be okay to do. Gotta find some hard info on that.  Although, adding launch parameters -language english, -language "english" in case of Russian version does not help. Players with other versions report that it does help.  As can be seen during game installation, the sound files alone take up about ~33 GB of disk space, and according to Origin's solution to Worldwide PC version, these files contain localization for every language available. It's just the rights to access them depend on version.    Note: it's important that the solution does not break any rules and is not outright illegal. Otherwise it may be removed from this site by a moderator, or, in worst case scenario, lead to some player's game and account being locked. So if you post something suspicious looking, be sure to include some links to official statements that allow such actions. Can the Universe be deterministic and still allow free will? Good reading on the Keldysh formalism I'd like some suggestions for good reading materials on the Keldysh formalism in the condensed matter physics community. I'm familiar with the imaginary time, coherent state, and path integral formalisms, but lately, I've been seeing Keldysh more and more in papers. My understanding is that it is superior to the imaginary time formalism at least in that one can evaluate non-equilibrium expectations. Is there any measurable time dilation when Earth reaches perihelion? Can we measure such a phenomena relative to the motion of the outer planets? Good practices for organizing notes How long do Tenacious and Unsung Hero badges take to be awarded? Just curious whether the process takes a while, and whether it scrapes through history to determine if it was once valid or not. Currently, I have 6 0-vote accepted answers and 20 1+-vote answers (), and that makes it > 5 and > 20% but not for long if voting goes up or down from here. ;-P  Update:  Special thanks to Grace Note for pointing out the  to follow. I upgraded this to a bug because it's been 48 hours during which the criteria supposedly were met. 6 0-votes, 20-23 1+ votes during the whole period. The criteria only last so long, so it may go out of scope soon. If it only checks every 3 days, I'm not sure if that's intentional or a bug. Distribution of the digits of Pi Can anything be stated about the distribution of the digits of Pi, i.e., if I were to sample n digits of Pi, can anything be said about the probability to observe certain digits, or is there any reason to assume that they would not be evenly distributed? This is purely a curiosity question. How do I use SSMS to compare Database 1 Table 1 against Database 2 Table 1? I have two databases - Database1 and Database2.  Both databases contain a table that has similar structure, exemplified as follows:   =========================================================================================== | ID | Name | PhoneNoFormat | DialingCountryCode | InternationalDialingCode | InternetTLD | =========================================================================================== |    |      |               |                    |                          |             | ===========================================================================================   However, due to some reason, (a) one of the tables in one of the databases has data that is not exactly the same as (b) that contained in the other table in the another database.  So, how can I compare Database1.Table1 against Database2.Table1?  I tried using the following query, but nothing happened so was wondering if I have to rewrite it:  SELECT MIN(TableName) as TableName,        ID,        Name,        PhoneNoFormat,        DialingCountryCode,        InternationalDialingCode,        InternetTLD  FROM  (    SELECT  'Table A' as TableName,           A.ID,           A.Name,           A.PhoneNoFormat,           A.DialingCountryCode,           A.InternationalDialingCode,           A.InternetTLD    FROM [D:\DATABASE1.MDF].[dbo].[Table1] AS A    UNION ALL    SELECT 'Table B' as TableName,          B.ID, B.Name,          B.PhoneNoFormat,          B.DialingCountryCode,          B.InternationalDialingCode,          B.InternetTLD    FROM [D:\DATABASE2.MDF].[dbo].[Table1] AS B  ) tmp  GROUP BY ID, Name, PhoneNoFormat, DialingCountryCode, InternationalDialingCode, InternetTLD  HAVING COUNT(*) = 1  ORDER BY ID Automating "Stay Awake" I use my personal Android smartphone for development. Every morning, I go to Settings \ Developer Options \ Stay Awake and check the box.  At the end of the day, I uncheck the box — since otherwise any notification (including the "fully charged" one) will trigger the screen on, and it will stay on from that point on.  How can these two operations be automated? parallel thermostat I have a venter room heater in a cabin. It uses a milivo;t thermostat. I am hooking it up to a wifi thermostat using a relay and 24 volt power supply. My concern is that if the power goes off that the thermostat will not power the unit on. I currenty have a digital thermostat that controls the unit and works great. can I wire the current thermostat to the wifi in parallel so if power goes off it will still allow the heater to turn on. If I can how do I wire it? Addon scripts overriding each other From time to time, I need to typeset Welsh. Sometimes, I need to typeset citations and bibliographies in Welsh. I think that last time I did this, I may still have been using BibTeX although I am honestly not sure. In any case, my entire work-flow now uses biber and biblatex...  I found  on changing the names of things, including the names of things used by biblatex. However, that cannot deal with the case of an unsupported language.  Suppose that I want to typeset a document in Welsh:  \documentclass[a4paper,welsh]{article}  \usepackage{babel} \usepackage[utf8]{inputenc}% welsh needs utf8x but biblatex doesn't like it \usepackage[T1]{fontenc}% not great for Welsh but the best pdfTeX can do \usepackage{csquotes}% doesn't like Welsh though biblatex likes csquotes on account of babel... \usepackage[backend=biber]{biblatex} \bibliography{biblatex-examples}  \title{Fy Nogfen} \author{Rhywun}  \begin{document}   \maketitle   \tableofcontents   \section{Cyntaf}   \autocite{westfahl:space}    \printbibliography  \end{document}   There are multiple problems in such a case. (One is that I need utf8x but can't use it on account of biblatex. Another is that I need utf8x at all. Another is that biblatex likes csquotes but csquotes doesn't do Welsh. But these are irrelevant to this question.)  The output is as follows:    Note that the use of the English citation is just so this is easy to reproduce. Obviously, the content of the reference might well be in Welsh. (Though it might be in English, too.)  As can be seen, while elements of the document controlled by babel are handled correctly, those under the control of biblatex are not. However, I cannot simply modify the solution offered by lockstep for changing strings to customised English variants. That is, I can't just use a Welsh version of  \DefineBibliographyStrings{english}{%   bibliography = {Works Cited},   references = {Works Cited}, }   because biblatex has never heard of it.  What is the most appropriate way to configure biblatex for use with an unsupported language? Proving $\sum_{k=1}^n{k^2}=\frac{n(n+1)(2n+1)}{6}$ without induction I was looking at: $$\sum_{k=1}^n{k^2}=\frac{n(n+1)(2n+1)}{6}$$  It's pretty easy proving the above using induction, but I was wondering what is the actual way of getting this equation? I'm reading through  for the , which contains this figure on page 16:    This is of course an instrumentation amplifier that apparently uses an inverting amplifier's output instead of a ground in the lower-right corner of the above figure, but what really perplexes me is the 100 k&Omega; resistors attached directly to the noninverting inputs of three of the four amps. I don't recall seeing an instrumentation amplifier circuit in books or application notes that have them, and all of the instrumentation amplifiers I've built using the three op-amp scheme works fine without them.  The datasheets specifies an input resistance of 1012 &Omega;, which is 10,000,000 times greater than 100 k&Omega;, so it doesn't seem to add anything to the already high-impedance JFET inputs. I thought perhaps it has something to do with input bias currents, but that's just me making a wild stab in the dark.  Curiously, figure 26 in the same datasheet (page 18) shows a two-op-amp version of an instrumentation amplifier without the 100 k&Omega; resistors at the noninverting op-amp inputs!  What's the purpose of the 100 k&Omega; resistors at the noninverting inputs in the above circuit? Am I missing something completely obvious?
