Answer : With the recent release of bootstrap 3, and the glyphicons being merged back to the main Bootstrap repo, Bootstrap CDN is now serving the complete Bootstrap 3.0 css including Glyphicons . The Bootstrap css reference is all you need to include: Glyphicons and its dependencies are on relative paths on the CDN site and are referenced in bootstrap.min.css . In html: <link href="//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css" rel="stylesheet"> In css: @import url("//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css"); Here is a working demo . Note that you have to use .glyphicon classes instead of .icon : Example: <span class="glyphicon glyphicon-heart"></span> Also note that you would still need to include bootstrap.min.js for usage of Bootstrap JavaScript components, see Bootstrap CDN for url. If you want to use the Glyphicons separately , you can do that by direct

Answer : You can with a style, but you have to add it to the main Theme declaration. <resources> <!-- Base application theme. --> <style name="Your.Theme" parent="@android:style/Theme.Holo"> <!-- Pointer to Overflow style ***MUST*** go here or it will not work --> <item name="android:actionOverflowButtonStyle">@style/OverFlow</item> </style> <!-- Styles --> <style name="OverFlow" parent="@android:style/Widget.Holo.ActionButton.Overflow"> <item name="android:src">@drawable/ic_action_overflow</item> </style> </resources> You also can change it dynamically, which I go into detail about here: Changing the Android Overflow menu icon programmatically For those who can't get it to work try this WITHOUT the "android:" namespace. <item name="actionOverflowButtonStyle">

Answer : Is there any way to access to the $VAR by just executing export.bash without sourcing it ? Quick answer: No. But there are several possible workarounds. The most obvious one, which you've already mentioned, is to use source or . to execute the script in the context of the calling shell: $ cat set-vars1.sh export FOO=BAR $ . set-vars1.sh $ echo $FOO BAR Another way is to have the script, rather than setting an environment variable, print commands that will set the environment variable: $ cat set-vars2.sh #!/bin/bash echo export FOO=BAR $ eval "$(./set-vars2.sh)" $ echo "$FOO" BAR A third approach is to have a script that sets your environment variable(s) internally and then invokes a specified command with that environment: $ cat set-vars3.sh #!/bin/bash export FOO=BAR exec "$@" $ ./set-vars3.sh printenv | grep FOO FOO=BAR This last approach can be quite useful, though it's inconvenient for interactive use sin

Answer : Just use this: colspan="100%" It works on Firefox 3.6, IE 7 and Opera 11! (and I guess on others, I couldn't try) Warning: as mentioned in the comments below this is actually the same as colspan="100" . Hence, this solution will break for tables with css table-layout: fixed , or more than 100 columns. I have IE 7.0, Firefox 3.0 and Chrome 1.0 The colspan="0" attribute in a TD is NOT spanning across all TDs in any of the above browsers . Maybe not recommended as proper markup practice, but if you give a higher colspan value than the total possible no. of columns in other rows , then the TD would span all the columns. This does NOT work when the table-layout CSS property is set to fixed. Once again, this is not the perfect solution but seems to work in the above mentioned 3 browser versions when the table-layout CSS property is automatic . Hope this helps. If you want to make a 'title' cell that spans all columns, as h

Answer : If you're interested in creating a new dict without using intermediary storage: (this is faster, and in my opinion, cleaner than using dict.items()) dic2 = dict(dic0, **dic1) Or if you're happy to use one of the existing dicts: dic0.update(dic1) Here are quite a few ways to add dictionaries. You can use Python3's dictionary unpacking feature. ndic = {**dic0, **dic1} Or create a new dict by adding both items. ndic = dict(dic0.items() + dic1.items()) If your ok to modify dic0 dic0.update(dic1) If your NOT ok to modify dic0 ndic = dic0.copy() ndic.update(dic1) If all the keys in one dict are ensured to be strings ( dic1 in this case, of course args can be swapped) ndic = dict(dic0, **dic1) In some cases it may be handy to use dict comprehensions (Python 2.7 or newer), Especially if you want to filter out or transform some keys/values at the same time. ndic = {k: v for d in (dic0, dic1) for k, v in d.items()} >>> dic0 = {&#

Answer : A change that came in with this commit since version 0.10.0 . When a container is started for the first time, it will execute files with extensions .sh that are found in /docker-entrypoint-initaws.d . Files will be executed in alphabetical order. You can easily create aws resources on localstack using awslocal (or aws) cli tool in the initialization scripts. version: '3.7' services: localstack: image: localstack/localstack environment: - SERVICES=s3 ports: - "4572:4572" volumes: - ./aws:/docker-entrypoint-initaws.d With a script in directory ./aws/buckets.sh : #!/bin/bash set -x awslocal s3 mb s3://bucket set +x Note: the set [-/+] x is purely there to turn on and off outputting of the commands being executed. Will produce this output: ... localstack_1 | Starting mock S3 (http port 4572)... localstack_1 | Waiting for all LocalStack services to be ready localstack_1 | Ready. localstack_1 | /

Answer : You get this try running pull first to integrate your changes whenever your local branch and your remote branch are not on the same point, before your changes. remote branch commits : A -> B -> C -> D local branch commits : A -> B -> C -> Local_Commits Now clearly, there's a change D that you don't have integrated locally. So you need to rebase , then push, which will lead to the following. remote branch commits : A -> B -> C -> D local branch commits : A -> B -> C -> D -> Local_Commits To solve your issue, do the following git pull --rebase origin branchname git push origin branchname I was getting this message in my Azure DevOps Repos environment because the server had a branch policy on the master branch that requires pull request approval and I was trying to push to master directly. Even after pull and rebase the same message appears. I don't think VS Code really knows how to interpret this specific err
