For this 20 years you have inspired & helped countless developers. I remember, you maintained a spring based framework that was inspired by rails and helped quickly boostrap new projects. it was some where around 2008/09. I don't remember the name of it though... Discovered your blog almost after 15 years. Good to see you are still going strong.

Just started reading, and i am too loving it, full of best practices and patterns, little bit slow read for me, but planning to finish it soon. Covers multiple dimensions of a secure software, Definitely a good read.

Hello Marcus,

I can't recommend any specific brands because I'm just using the ones from the box and haven't tried any others.

Happy Birthday to my sweet Jack! You come from a long line of engineers. Your Great Grandfather, my dad, went to Illinois Institute of Technology. Your Great Uncle Jack and Great Uncle Michael, my brothers, went to Purdue. And your Grandfather, your mom’s dad, went to Rose-Hulman Institute of Technology. We were in Boulder the other night and found out that CU has an engineering school. I do love that Abbie is so close. I can’t wait to hear of all future endeavors!!! Love, Grammy

Reza - I don't know if two monitors is the best productivity improvement. Canceling meetings and getting time to focus without distractions is the biggest productivity improvement, IMHO.

I think 38" is big enough. 49" seems a bit wide.

Re: Dell UltraSharp U3818DW 38" Curved Monitor Review

2021-06-12T00:08:31-06:00

How much productivity improvement does this give compared to two smaller monitors? would you consider bigger e.g. 49" ?

Hello Linda - it's nice to hear from you! That's cool that your son and I have the same name. :)

My dad's name is Joseph Edward Raible and is from Beacon, New York.

Re: Happy Birthday, Jack

2020-10-20T17:03:09-06:00

My older son's name is Matt Alexander Raible. As most mothers are, I insisted on calling using the name Matthew, which lasted until he got to school. On a whim I googled his name, (I'm 72 and getting bored with staying at home) and found that there are other Matt Raibles out there, unfortunately one is deceased. I was surprised because Raible is not that common. On reading this article, I saw the name, Jack, who I assume is your son. My Matt also has a son Jack. Your sound as if you have an interesting life. My Matt is a contract specialist for FEMA, He's married to his high school sweetheart, and they have three children, and lives in VA. He'll probably be ticked off that I told this much about him, but you seem that you aren't a closet ax murderer or. We are originally from PA.

@Robert: I use 3200 x 1333 and SwitchResX allows me to go up to 7680 x 3200. 3840 x 1600 is the highest resolution that has HiDPI.

Yes, it looks retina quality, but I did notice a trailing shadow issue earlier this week.

Thanks for some of these solutions - the auto-wake has been driving me crazy, so I've just been turning off the monitor at night.

For window snapping, the best solution I've found is BetterTouchTool. You can set up custom snap areas / shortcut keys for any window configuration that you want. Here's the details: https://docs.bettertouchtool.net/docs/104_snap_areas.html

Does your HDMI inputs work normally? I have an issue where both the ports don’t work for mine.

So it appears that my SG isn't open enough - right? (nope) my SG is configured with the appropriates ports open. This also happens on a different instance/vpc/sg, etc that is wide open 0.0.0.0/0 as inbound. Same problem. weird.

This process is overcomplicated. In the end I ended up using minehut.com. I'm not trying to sound like a shill but if you're reading this article you're probably just looking for a free server for you and your friends, and minehut does all that for free, with no risk of being charged unless you choose to. U can also modify all the game files and install mods and everything so i def recommend, that's what I ended up using after attempting this article, so try it out: https://minehut.com/

Re: Setting up a Minecraft Server in the Cloud

2019-09-20T00:45:48-06:00

A few suggestions I had from my own issues:

On step 10 of step 1, if you are not running linux and running windows it will not work, but this article should help: https://linuxacademy.com/guide/17385-use-putty-to-access-ec2-linux-instances-via-ssh-from-windows/

On step 1 of step 2, Minecraft changed the download location, so simply changing the number won't work. Here's the most recent download link you should use instead: https://launcher.mojang.com/v1/objects/3dc3d84a581f14691199cf6831b71ed1296a9fdf/server.jar

In case there is an update, check the "inspect element" of the download button on minecraft.net and copy the new link to download.

Step 2 and 3 of step 2 replace "minecraft_server.1.8.8.jar" with "server.jar"

If you get the error:

"Exception in thread "main" java.lang.UnsupportedClassVersionError: 
net/minecraft/server/MinecraftServer : Unsupported major.minor version 52.0 
at java.lang.ClassLoader.defineClass1(Native Method) at

java.lang.ClassLoader.loadClass(ClassLoader.java:358) at 
sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:482)"

Go here and follow all of the steps, then come back: https://blog.knoldus.com/installing-latest-oracle-jdk-on-linux-ec2-instance-centos/

And NEVER proceed to the next step until you get the confirmation that everything that was supposed to happen happened.

Okay that's it hope it helped, good luck.

This looks like a fascinating concept. I'm working on setting up a minecraft server for my daughter's girl scout troop as they are very interested in programming, and various other things STEAM, and I expect learning to write Minecraft mods and then get to play with them together could be very good for them. I wish more than this first installment was available, but I'm quite interested in the ideas presented in use of autoscaling and spot requests for low cost. I also plan to have some amount of 'off time' scheduling as I don't see a need to run the server when the young ladies should be at school and/or sleeping. My goal is to try to keep the costs under $5/mo. and then expand on the idea to give each scout the ability to run their own sandbox servers to work on their mods.

March 2019 - Intuit still sucks. Buggy website, buggy software, hideous merchant services and they despise developers (worst APIs ever written, crappy documentation, obscure or nonfunctioning example code, the list goes on).

Rohit: the AppFuse project was retired in 2016. These days, I recommend you look at JHipster instead.

Hello SmartAsh: I'm not sure, but please let me know if you figure out a solution! You might try asking on Stack Overflow.

What if the same directive has to support lesser width carousel elements? In this case, for larger desktops carousel should show 6 chunks instead of 5. And the component should support this dynamic chunking based on the width of elements. How do we achieve this through the above directive/service?

Hello,

Thank you for the great tutorial!

I have the same errors come that Daniel McLaughlin had back on 11/27/2017.

Matt Raible was kind enough to reply pretty quickly, but Matt, I am not sure how to upgrade the Jave to Jave 8, would you please provide a few instructions for upgrade the Java version when you have the time.

Thank you for your great work and for your time, Happy Holidays! :)

That's a pretty strong statement Cristian. Thanks! I'd love to checkout Orval sometime. I also heard Westvleteren was worth visiting. Cheers!

My favourite conference speaker :) Btw : you should check Orval beer in Belgium.

Daniel: you're likely seeing this error because minecraft.jar was built with Java 8, and you're trying to run it with Java 7. Upgrade to Java 8 as your runtime and you should be good to go.

Thanks Josh! I'm glad you like our Spring Boot support. It's been mostly written by Brian Demers so he deserves all the credit. ;)

Keep up the solid work. You have made a tremendous impact on growing the developer community around Okta. I was hesitant to use Okta over Auth0, but library support for Springboot is a solid plus. Good work.
