How to Execute a Stored Procedure in Laravel 5.6
I’ve been stumped on this and tried everything I can think of but I can’t get Laravel to execute a working mysql query to reorder an ordering column when deleting a row.
Here’s a sample simplified query, which works directly in mysql:
1 | SET @number = 3; UPDATE images SET order = (@number := @number + 1) WHERE id >2 AND project_id = 10 |
Laravel code that doesn’t update the database but throws no errors:
1 2 | $sql = 'SET @number = 3; UPDATE images SET order = (@number := @number + 1) WHERE id >2 AND project_id = 10'; DB::raw($sql); |
Other things I’ve tried which throw errors including saying there’s an error in the query:
1 2 3 4 5 | DB::unprepared($sql); DB::statement(DB::raw($sql); DB::statement($sql); DB::update($sql); DB::select($sql); |
I’ve also tried splitting it the statements with no luck:
1 2 3 | DB::statement("SET @number = 3;"); $sql = 'UPDATE images SET order = (@number := @number + 1) WHERE id >2016 AND project_id = 10'; $update = DB::update($sql); |
I tried a few other things which I didn’t log in Git but I had no luck getting any of it to work. I asked for help on the forums and people told me to use Laravel’s Eloquent model to update rows one by one which is pretty inefficient. You get extra trips over the network (especially important when the code is not on the same server as the database server since you can get dropped calls), extra connections to the server, the extra overhead of processing the query on the server and in the database, etc instead of just having mysql make the update.
The recommended solution may not seem like a big deal but I’ve run into issues where client connections have been dropped mid-update and left a table partially renumbered.
As a last resort and workaround, I opted to use a stored procedure to accomplish my goal. That presented its own can of worms as searching for examples on how to execute stored procedures in Laravel 5.x was also not easy. There’s nothing in the documentation and all the examples I found didn’t work.
Here’s what worked for me with Laravel 5.6, with mySQL 5.6.38:
1 | DB::statement('call spRenumberComments(?, ?)', [$id, $projectid); |
Self-signed SSL certificates not working with MAMP and Chrome
I use MAMP Pro for most of my PHP development and Chrome has annoyingly been blocking the self-signed SSL certificates MAMP generates, saying the certificate is not valid and “Your connection is not private”:
Thankfully, I found an easy solve to fix this. These steps assume you’ve created a host in MAMP. You’ll need to go to the SSL tab of the host you are trying to fix and
- Check the SSL button
- Click the self-signed certificate button.
- Fill in the fields in the dialog modal and click Generate
- You’ll be prompted to save the certificate. Choose whatever location you’d like.
- Click on the circle with the arrow to open the directory where the certificate was saved.
- In the finder window that opens, double click the .crt file (be sure it’s the same file name that’s in the SSL window in case you have multiple).
- In the Add Certificate window, click Add. I testing adding it to login and system and both worked, so add whichever you prefer.
- In the Certificates Window, double click the certificate. It’s easier to filter by name if you have a lot of items.
- In the next modal window, choose Always Trust from the dropdown.
- Close out the next confirmation window, and you’ll be prompted to authenticate with your mac login to save the updates.
Go back to Chrome, and reload the page and the certificate should work now:
How to get shape type in Visio using VBA?
I’m working with a Visio 2016 file with over 100 tabs and need to extract the data (mainly text, connector from/to, and shape) for data processing for a processing engine. I was trying to figure out how to get the shape type name in Visio using VBA. For example, in a flowchart, I’m trying to figure out how to tell if a shape is a process, decision, data, etc. The
1 | visShape.Type |
property seems to always return 3 which appears to be visTypeShape from https://docs.microsoft.com/en-us/office/vba/api/visio.visshapetypes. After hunting through all the available properties on the Shape object, I found that the shape.Master.Name property will return the shape name, but you need to check if it’s Nothing first in case it’s not a shape.
I didn’t do that and it kept breaking the script originally because some of the pages had text fields and the first few items on the first sheet I was working with were text boxes. Hopefully this snippet will save you the time I wasted figuring it out.
1 2 3 4 5 6 7 8 9 10 11 | Public Sub GetShapeAndID() Dim visShape As Shape For Each visShape In ActivePage.Shapes If Not visShape.Master Is Nothing Then Debug.Print visShape.ID & " - " & visShape.Master.Name End If Next End Sub |
How to get website average latency in BASH
I was working on a project today and wanted to be able to get the average latency for an API that I was working on. Performance is a concern because we’re running the API over a VPN, and then SSH tunneling over to another server. I wanted a quick way to do it and wrote a little bash function that will calculate the average for me. I couldn’t find an example on how to do this online so I’m sharing in case anyone else runs into the same issue.
This is tested on Mac only. Add these two functions to your .bashrc and do a shellupdate in terminal to load the latest, or just grab my dotfiles from my github: https://github.com/gregvarghese/dotfiles
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | curlb(){ curl -s -o /dev/null -w '%{time_starttransfer}\n' "$@" } # Usage: # latencyavg [# of times to run] [URL] function latencyavg() { time=0.00 for (( c=1; c<=$1; c++ )) do num1=$(curlb $2 -H 'Accept-Encoding: gzip, deflate, sdch' -H 'Accept-Language: en-US,en;q=0.8,ja;q=0.6' -H 'Upgrade-Insecure-Requests: 1' -H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.86 Safari/537.36' -H 'Connection: keep-alive' --compressed) echo "$c - $num1" time=$(echo "$time + $num1" | bc -l) done echo "Total Time $time" echo $(echo $time / $1 | bc -l) } |
Usage example:
1 | latencyavg 20 https://www.godaddy.com |
How to remove wrapping tags in PHP Storm
How often do you code something and need to delete a wrapping link or div? I was using PHPStorm and had grabbed some code from another file that had links in the tags which weren’t needed in the new file. I didn’t want to manually remove each link and after a quick look around PHPStorm’s menus, discovered that PHPStorm has a really useful command to remove the wrapping element for you.
Select the element, then from the menu, choose Code > Unwrap/Remove… or use the keyboard shortcut, Command + Shift + Backspace and then choose the appropriate wrapping element to remove.
How to Prevent Raspberry Pi Zero from Blanking or Sleeping
I was setting up a Raspberry Pi Zero in an office to use for displaying a slide show of pictures on a TV in the waiting room and dismayed to learn it would constantly go to sleep after a few minutes. I researched and tried setting the consoleblank=0 in config.txt with no luck along many other solutions, but learned none of them worked for the Raspberry Pi Zero.
1 | sudo apt-get update && sudo apt-get install xscreensaver |
I’m not sure why, but I got an error that some dependencies were not installed. If that happens to you as well, run this command in terminal:
1 | sudo apt-get --fix-missing |
and then run the install for xscreensaver again
1 | sudo apt-get install xscreensaver |
Now under Preferences, you’ll see a new option for screen saver:
On the Display Modes tab, you’ll see a drop down for Mode. Choose “Disable Screen Saver”:
Your raspberry pi zero will now no longer go to sleep.
How to fix VMWare Fusion Pro 10 “Cannot find a valid peer process to connect to”
I recently got a new mac and was migrating a VMWare Windows Virtual Machine from my other computer. When starting the virtual machine, I received a random message from VMWare Fusion saying “Cannot find a valid peer process to connect to.”
The fix was rather simple as it was just Apple blocking VMWare from running. To fix it, follow these steps:
- Open System Preferences by searching in Spotlight or clicking the gear icon in the dock.
- On the top row there is an icon for Security and Privacy – Click that icon
- Near the bottom of the screen that appears the following statement
“System software from developer “VMWare, Inc.” was blocked from loading” - Click Allow
Windows 7 & 10 How to Bulk Unblock Blocked Files
While setting up a new computer, Windows was throwing up warnings that files transferred from a backup drive might be unsafe. The files were text and images, so the warnings were safe to ignore but the directory had over one thousand files. Rather than unblocking each file manually, Windows PowerShell makes it easy to unblock files in bulk.
Load up Windows Powershell:
- Press Win + R on the keyboard to open the Run dialog.
- In the Run box, type powershell
For one folder without subdirectories, this snippet will do the trick.“$env:userprofile\Downloads“ tells PowerShell to use the Download folder for the logged in user and unblocks all files in it. Change this to the folder path you need if it’s not the Downloads folder.
1 | get-childitem “$env:userprofile\Downloads“ | unblock-file |
If you have sub-directories and need to unblock everything, use the -Recurse flag:
1 | dir “$env:userprofile\Downloads“ -Recurse | Unblock-File |
Want to see a report of files to be unblocked before running it? The -WhatIf flag will show you without executing.
1 | dir “$env:userprofile\Downloads“ -Recurse | Unblock-File -WhatIf |
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:
- 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.
- Scroll down the list until you get to the Excel formats (XLS):
- 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:
- 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.
