Mobile connections especially while moving in a car or train will always have a lot more latency and packet loss than a typical DSL or cable connection.
By default compression is not enabled for outgoing ssh connections on OS-X.
Very simple compression is no problem for modern CPUs and even on a gigabit network it is faster to compress data first before sending it over the network instead of leaving it uncompressed. However compressing data that can’t be compressed anymore (like JPEG files) makes no sense. If your typical ssh traffic is not .jpeg or .zip files then read on.
UPDATE 10/27/2014: This post applies to OS X Mavericks and Mountain Lion as well but has been corrected to address the most recent version.
I really like VMware and i love my Mac but being forced to update a software that works perfectly is something i don’t like at all. So after installing OS X Yosemite there is this dreaded situation again. Pay for an upgrade to VMware Fusion just because VMware refuses to patch their next recent version.
So i decided to move to Virtual Box which is free on OS-X. Here’s how to import / convert your old VMware image to Virtual Box within few minutes.
OS-X Mountain Lion introduced a feature to prevent the automatic execution of third party software not downloaded from the Apple App-Store.
It cost me quite some time to figure this out.
Consider this scenario: You are using CFHTTP to request some JSON data from an external API. The data is sent UTF-8 encoded and everything is fine as long as the API uses Content-Type: text/html
. Now if the Content-Type changes to application/json
everything will break and the characters get messed up. Now what if you can’t tell the external API to use text/html
as Content-Type? Besides application/json
is perfectly fine and UTF-8 by design.
This article describes the upload of a file to Amazon S3 purely on the client. This means the server (NodeJS) in this case never gets to see / has to handle the actual file the user is uploading.
To upload files from within NodeJS the npm (Npm) module Knox can be used.
Node.js 0.4.9 or higher is required as a runtime environment for our example.
Running wkhtmltopdf and wkhtmltoimage to create PDF files from HTML files on a Mac is easy and simple. When you need to install it on a non-mac production server a little bit of work is involved.
Working with SQL databases is easy and straightforward in Coldfusion.
Looping and creating HTML output from queries is easy too.
Amazon’s CloudFront is great to reduce load on local servers if you are serving a lot of static files or files that can have a long cache timer set.
Sometimes you need to remove files from the CloudFront caches and this is where the Invalidation feature comes in.
An invalidation batch-request invalidates one or more files (paths) from all CloudFront edge location.
