List of my must-have Alfred Workflows

Use a mac? You’ll want to grab Alfred App. I’m finding it an invaluable replacement for spotlight and the workflows allow me to supercharge my workflows. It’s so useful that I’ve purchased the Powerpack lifetime license.

In addition to the standard features, here are a list of the most useful workflows for dev/tech:

Kill process – by Nathan Greenstein (@ngreenstein)
I use it as an activity monitor for CPU usage, and from there I can easily force quit any process if needed. It’s easier to see all processes on the Alfred UI instead of opening Activity Monitor on your mac. There’s also the workflow Kill Application – by Sebastian Hallum Clarke (and also on his site you can find other cool workflows).

Timer – by Daniel Bader
I use this one a lot. It’s super simple and by writing “Timer” and the number of minutes, you can easily set a reminder. It’s great for anyone using the Pomodoro technique or even if you leave something on the stove and want to go back to work.

Copy SSH Public Key – By oldcai
This one saves me time when I need to deploy my SSH key on a new server. Type ‘pk [ssh key file name]’ and it’ll copy the ssh key to the clipboard.

Incognito – by Nedwood
I find myself using this when I need to test a page and bypass the cache. Type ‘incog [url]’ and it’ll launch a new chrome window in incognito mode.

Find Folder by Samvlu
Finds a folder by name. I find this is faster than spotlight in just about every search.

Smart Folders by Deanishe
List all the Smart Folders/Saved Searches (same thing) on your system and drill down into their contents. Works in much the same way as Alfred’s File Filter, but Smart Folders are also available outside Alfred and are a bit more flexible.

For example, you can configure a Smart Folder to show all video/audio/image files without having to specify each different filetype individually. If you already use Smart Folders, this workflow can save you the work of re-implementing them as File Filters.

What’s more, you can exclude specific filetypes with a Smart Folder, which Alfred cannot do.

Advanced Google Maps Search by stuartcryan
This workflow gives you some quick and dirty shortcuts into Google Maps:

Commands:

To Configure:

mapsethome <home address including street number, name, postcode> (i.e. what you would type into Google Maps)
mapsetwork <work address including street number, name, postcode> (i.e. what you would type into Google Maps)
Commands for Use:

maps <query> – Search Google maps for an address
dir <query> to <query> to <query> etc (seperate multiple addresses with ” to ” minus the quotes, and you will get a multiple location search)
dirfw Show directions from Work to address
dirfh Show directions from Home to address
dirtw <query> Show directions from query to Work address
dirth <query> Show directions from query to Home address
trafficw – Show traffic from Home to Work
traffich – Show traffic from Work to Home

StackOverflow Search by deanishe
If you use stackoverflow as much as I do, this is a must-have.

Date Calculator
I find myself needing to calculate differences between dates in my personal life a lot lately. This workflow saves me a lot of time to do that. Want to know how far Christmas is away in days? ‘dcalc 12-25-16 – now d’ returns the number of days (assuming you’re using the US short format like I am).

Wifi Control by miroman
All my Macbooks periodically have issues with wifi. I’ve never been able to figure out what’s causing it but I use Wifi Control to restart the wifi which allows me to connect successfully.

Bugnot by vitor
If you use bugmenot at all, this is a useful extension to get logins without loading a new tab. Type ‘bn domain.com’ and you’ll get a list of matching passwords to use.

 

 

How to Fix ‘Converter Failed to Save File’ with Excel 2016

I recently upgraded to Office 2016 on my Windows 10 desktop and was getting the error “Converter failed to save file” when double clicking on the file along with an “There was a problem sending the command to the program error” every time. I finally had enough with the annoyance to troubleshoot it and figured out a solve.

If you have the same issue, here’s how to fix it:

  1. Open your Default Programs configuration from the Control Panel. On Windows 10, you can hit start, type Default Programs, and it’ll open the app.
  2. Scroll down the list until you get to the Excel formats (XLS):
    Default Programs
  3. If you see anything other than Excel as the default, you’ll need to change the default to Excel. For me, the issue was the Open XML Converter not being installed anymore after upgrading to 2016. To change the default, select the format, click the “Change Program” button and select Excel 2016 from the list of apps that pops up and click OK to set the association:
    App Select
  4. You’ll need to do this for each format in the list to correct it. The most common formats you’ll use are XLS, XLSX, & XLT.

How to test email sending in Laravel 5.3 using artisan tinker

I’m building a Laravel app and ran into an error when trying to send mail but wasn’t getting an error back since the request was posted through ajax. If you’re trying to troubleshoot it, artisan tinker app is very useful to get more information on the error.

Fire up terminal/command line and run:

and then run the following snippet:

Change emails.test to point to a blade that works and populate the email you want to test.

You should either see a success/null message if everything was correct, or an error with details on what went wrong. The error I encountered required configuring 2FA in Gmail or setting the insecure app option up to send through Gmail for testing.

Cheap Macbook Pro Docking Solution for about $30

I typically prefer developing on my desktop and large dual screen monitor setup as opposed to my Macbook. Recently, I’ve gotten into more PHP development and developing on the Mac is proving to be a more enjoyable experience only because Windows is still a second class citizen for most PHP libraries/tools. I still wanted a larger screen setup, so I considered buying a docking station to hook up to a larger monitor but I soon learned they feature the ‘Mac Penalty’ in that they cost more than they should just because it’s for Apple products.

I already have two large monitors and figured my Macbook could serve as third screen. Then I did some thinking and realized I could use one of the monitors for both computers. Assuming you have two HDMI screens already hooked up to your desktop, this would save you $150+ and still allow you to be more productive.

  1. Get a copy of Synergy (http://symless.com/) for $10. It’s open source and can be built if you have the time, but a one time fee of $10 saves me the hassle of doing so. With this, you can share your desktop keyboard across all your computers with the one license and it’s cross platform so Linux support is included too.
  2. Purchase an auto HDMI switcher. I purchased the PORTTA PET0301S 3×1 Port HDMI Switch/Switcher for about $9.
  3. Be sure to get 2 HDMI cables if you don’t already have them on hand. I don’t like the Amazon Basic brand for these as I’ve had problems with the Mac and those cables hooking up to larger screens.
  4. Install Synergy on the desktop as a server. Install on the Macbook as a client and it should autoconnect.
  5. Plug the HDMI cable from the computer into the HDMI switcher, and plug the spare into the Macbook pro. Plug the “Out” end into the monitor.

When you plug your HDMI cable into the Macbook, the HDMI switcher will automatically switch to it and project the Macbook. Synergy will auto-connect as long as it’s running on both and you can share the mouse and keyboard between both and work seamlessly.

If you have an iPad and want to turn that into an additional screen, grab a copy of Duet Display on your desktop/Macbook and install on your iPad for $15.99, and viola, instant portable second screen!

How to repair permissions on Linux Apache /var/www/html folder

I recently ran into an issue where I could no longer FTP files to my Linux droplet when multiple users were uploading to the server. The server kept the user as the owner despite me adding them to the www-data group. This fix comes from my ex-boss, James Tomasino who was kind enough to provide some help since I was stumped. I’m sharing in case anyone else runs into the same issue and finds it useful.

You’ll need to fire up terminal, ssh to the server, and then execute these commands:

+s makes permissions sticky so that all files will inherit from the parent directory. This was the setting I was missing.

Open up /etc/ssh/sshd_config. I use nano so:

Hit CTRL+W and look for “subsystem” which is typically located near the bottom of the file. Change

to

If you already have files in the HTML folder, you’ll want to run these commands to reset the permissions:

 

(98)Address already in use: AH00072: make_sock: could not bind to address [::]:80 – error

I recently got handed a new Ubuntu droplet at work to setup and work on. I was going through the typical configuration to lock down the server and go to installing Apache when I suddenly ran into the error

(98)Address already in use: AH00072: make_sock: could not bind to address [::]:80 – error

I was a little surprised considering I had only run 4 commands total on a brand new installation. If you’re getting this error like me, you’ll need to find out what’s being bound to port 80 and then stop it. Use this command to get a list of anything that’s running on port 80.

For me, it turned out nginx was running and bound to port 80. If you have the same problem, run this command to stop it:

Now you should be able to start apache.

Copy File Context to Clipboard via Command Line, Git Bash (Mingw64), or Terminal

I’ve been spending more time switching from SVN to Git and learning the command line options. I’m finding a lot of the Mac Git terminal commands I run aren’t the same in Git Bash (Mingw64). One of the commands I use is the pbcopy command to copy the ssh key to the clipboard to paste into Github and Bitbucket accounts. I’m starting to use it more as I am learning managing Linux servers and adding my key to login. I’m adding it here as a cheatsheet for myself but I thought others may find it useful.

On Windows, you can run this command to copy your ssh key to the clipboard:

On Mac:

or if you want to view it in the terminal window:

How to Copy and Paste into the Digital Ocean VNC Console

I recently signed up for Digital Ocean to test droplets for my development and linux management testing. I was securing the server and setup fail2ban, disabled the root login, and created a user account but forgot to change the user name from root to the user name I selected in my SSH client profile. I ended up locking myself out of the server and had to resort to logging into the admin panel on Digital Ocean’s website and use their browser embedded VNC client to restore my access. I quickly discovered that one of the downsides of using this panel is that you can’t copy and paste commands. Luckily there’s a workaround and you can use the browser console to do sendkeys through Javascript.

Bring up the console in the browser developer tools. Here’s a cheat sheet for keyboard shortcuts:

BrowserDescriptionWindowsMac
ChromeOpen Developer Tools and bring focus to the consoleCtrl + Shift + JCmd + Opt + J
FirefoxOpen ConsoleCtrl + Shift + KCmd + Opt + K
Internet ExplorerAfter hitting F12, you have to click the console tab.
There’s no direct shortcut to the console tab.

Update 9-21-16

Ruden and Sebastiaan’s pointed out there was a bug in the code above. This updated snippet has support for characters when using shift characters like !@#$%^&*()_+

You’ll receive a dialog prompt to enter the copy to paste in. Please note that you need to click on the VNC console and hit enter to execute the command.

If you need to enter more than one command, just hit the up arrow on your keyboard in the console to get the script again for easy reuse.

How to fix “hacked by Moroccanwolf” WordPress site

A client of mine had their wordpress hacked and when you would load the site, it would simply display a message that said “hacked by Moroccanwolf”. I did some digging and luckily it wasn’t a major hack and they didn’t mess with the posts or other settings as a lot of the hacks do.

Quick Fix

  1. To fix it, you’ll need to connect to your database using an editor of some sort, such as PHPmyadmin.
  2. Once logged in, expand your database on the left.
  3. Click on ‘wp_options’.
  4. On the top right, click the ‘Browse’ tab.
  5. Look for ‘widget_text’ in the option_name field. (For my client, it was at row 90). You should see something similar to this:

Delete the entire tag and this  should restore your website. Now remember to change your logins and update wordpress.

How I Figured it Out

Most of the hacks I’ve seen are done through injecting javascript into the database somewhere which either force a redirect or something along those lines. Here’s the steps I followed to find it:

  1. To fix it, you’ll need to connect to your database using an editor of some sort, such as PHPmyadmin.
  2. Once logged in, click on your database on the left. Ensure you’re on the database and not a table.
  3. Click Export.
  4. Leave it to quick and click go.
  5. You should now see a textbox with a mess of SQL commands.
  6. Copy and paste into your favorite editor,
  7. Search for <script> and you should find something that doesn’t belong.  In this instance, that was the only thing I found of note.
  8. You’ll want to scan the rest of the database for things that don’t belong. Additionally, you’ll want to replace all the wordpress files and confirm no .htaccess files were created that give hackers write access.
