My Thoughts on Why Tweets Cannot and Should Not be Editable

With all of the buzz around Twitter looking for a suitor to sell to at the moment, it reminded me that one item always seems to come up when discussing how to use the social media platform. Not many days go by without someone in my timeline asking “Why can’t we edit our Tweets?”. Here are my thoughts as to why that’s the case.

There is nothing like having a great tweet go out and get lots of engagement, only to realize that there is a glaring typo, or grammatical error. I can’t even count how many times I’ve let one slip with a strange autocorrect that twisted the meaning up.

Bait (Tweet) and Switch

It’s as simple as the use-case where someone sends out a tweet that gets some heat. It could be lots of retweets, or favourites, or even just embedding into another platform. The whole idea of the micro-style of the 140 character platform is that it is a thought at a point in time which could be either a fleeting thought, or a deep idea. Either way you look at it, each tweet is a unique item.

Imagine if you retweet someone’s tweet saying something of a very opinionated nature. Let’s just use a political example where someone may say “If you don’t vote for Party A, you are doing your country a disservice”. That tweet will get a lot of retweets because all of the folks who support Party A are strong believers and want to share their belief.

Now, let’s take that same tweet and make it editable. The person behind the original tweet changes it from “If you don’t vote for Party A, you are doing your country a disservice” to something quite the opposite like “Party A is taking the country down. Thank goodness for Party B”. If you had been a retweeter of that original tweet, you would now have the entirely opposite opinion sitting in your timeline without your knowledge.

Edit and Drop Activity?

What if we say that editable tweets drop the previous activity? If the safety measure to avoid a bait and switch of the tweet is to disconnect it from the engagements (retweets, likes, etc.), then you may as well just delete and recreate the tweet.

This is nothing that is groundbreaking, or a crazy idea that I’m putting out. I just thought I’d put it out to maybe bring some context to it.

Cheers to the new buyer of Twitter, whomever it may be, and happy non-editable tweeting to everyone!

AWS Route53 Step-by-Step – Redirecting Domains GUI

While I’ve covered this one before with a specific two-step approach to do simple redirect.  This will repeat some of those steps with a new domain pointing to an alternate web site URL.  This is a real use-case example where I’ve bought a new domain that I want redirected to as the target.

Sample source zone: 

Sample target website:

Using Route53 to Redirect to a New URL

My sample domain was registered with Route53.  You can see the registration message here:


A Hosted Zone is created automatically as part of the registration process:


Highlight the radio button and use the Go to Record Sets button.  That lets us create a new entry with the Create Record Set button.  Because we want to redirect the default www zone, let’s create a CNAME record for that and directly assign in the Value field:


We need to redirect the root domain of as well, but we can’t use a CNAME for a root record.  This means we need to create a S3 bucket for the root zone.  Name it after the domain you’re redirecting:


Set up the Static Website Hosting section in the properties window for the S3 bucket, and put the target domain under the Redirect all requests to another host name section:


We may have to exit and reenter the Route53 zone to refresh, so once you’re done with that, set up a new A record, click the Alias radio button to Yes, and click the Alias Target field to trigger the drop down list where you can select the S3 website endpoint that matches the domain root:


Wait for a few minutes.  10-15 minutes will ensure that the TTL for the zone and record are passed and it forces a fresh request to the root domain.

Using the AWS CLI (aka AWS Shell) to Query Route53 Hosted Zones

You will need to install the AWS CLI on your machine, or you can also use my sandbox method to run it inside a VirtualBox VM to save installing in your workstation.

Once configured, we will use the following command to list all of the zones:

aws route53 list-hosted-zones-by-name


You will see all of the available zones come back.  Clearly that is more detail than we want, so let’s add a couple of parameters which will reduce the output to just the zone we want --dns-name (note the trailing dot is important).  That still returns a series of zones, so we also add the --max-items 1 parameter as well:


We can confirm the redirects using the cURL command for both domain names using the cURL command and the -IL parameter to show the HTTP response details:


In our next post, we will be doing some DNS record management using the AWS CLI to emulate the changes we did in the GUI in this article.

VMworld 2016 – Quick Takes on the Event and Announcements Part 2 of 2

Following on my earlier article, I wanted to cover a few more things about the VMworld event this year in Las Vegas. For the deeper technical announcements and some great overall event coverage, I recommend these blogs that are well worth the read:


  • Rene Van Den Bedem:
  • Julian Wood:
  • Dee Abson:


There are many other folks who’ve covered the event, but that should give you a good start on things.

Expo Hall and Las Vegas

There was a marked difference in the style of the event because of the venue. Having seen a similar Expo Hall and breakout session layout for a few years at the Moscone in San Francisco, the vibe was definitely different. The Expo Hall was laid out in a way that seemed larger by the length of the hall, but the depth of the hall was shorter. Was the rectangle smaller than the usual square? Probably not by much, but it did feel different.

My Turbonomic team proudly hosted a 30×30 booth with a massive LED theatre display across the top of the two-storey layout. Mark my words that next year will feature a few more booths like that. We like to lead the charge with new ideas to inspire others.

The overall flow of the Expo crowds felt lighter. While the number 23,500 was put out as the attendance, it didn’t feel busier in the hall at an one time. This may have been due to the physical layout, and many other factors. The buzz was definitely in the air as usual for the VMworld floor. Swag and product materials were being grabbed up at record pace in the first couple of days, which then turned into folks revisiting the floor to do some more deep-dive chats and really getting to the fun conversations that will help us all bring ideas back to the office.


This year also featured another round of the VMware hackathons. This is a great opportunity that I’ve waited to see at the event. Last year featured the DevOps area in the community lounge, and more focus was being put on moving up to the application layers and orchestrating across the infrastructure. The first hackathon didn’t get as much of a draw as this one did, so I’m encouraged by the uptake of this type of event at VMworld. Every infrastructure admin should take note of this trend and be ready to look for opportunities to observe, learn, and participate whenever possible in these types of events.

Byron Schaller, a good friend and Virtual Design Master alumni, was on the team who won the event which sent him home with a nice Intel NUC lab package and some great karma among the team. Byron is an example of someone who really sees the shift in the industry, and is running with it while also leading others in the community along with him. Chapeau to Byron on his win at the event, and I look forward to some future projects on public hackathons. I want to send a nod to the @VMwareCode team as well for hosting the event.

There will be a hackathon in Barcelona at the VMworld EU event as well –


This is the reason I attend conferences. Period. Technical learning is a byproduct of community IMHO. The peer group that you get to interact with makes the attendance of live events worthwhile more than anything. Having the opportunity to chat with the speakers after sessions, or to meet the engineers who wrote and maintain products and integrations, is something that you can only do at such an event.

Whether it is meeting at the parties, or in the community lounge, there are lots of events that aren’t happening in the breakout sessions and expo hall. This is something that becomes more of the event than the breakouts as I continue to attend. You may also find that you spend much more time with one-to-one and group collaboration among the community.


Attendees of the event are able to get access to the video replays of most of the sessions. This is a huge asset for folks who quickly learn that getting to all the sessions you would like to in person is a near impossibility. There is a huge gain in being there in person as well, but it is great to be a able to consume much of the content at our own pace back at the office or in our free time at home. Make sure to also take a look at William Lam’s Github page for the code to view, download, and check which were the top sessions and other notable lists in JSON format.

My Overall Take

If you take anything away from this event, take this message: learn to code more, learn about the cloud more, ask why these matter to your business, and to yourself.

No matter what your comfort level is with scripting and coding, you can do a little more, or a lot more. I’m not a programmer…at all. Programming both impresses and frightens me in a way. I learned from my friend and Virtual Design Master alumni Rob Nelson that if you write a one-line PowerShell, your a coder. There is no certification for it.

The move up the stack and towards more orchestrated infrastructure is inevitable and necessary. It doesn’t need to be Internet of Things scale to require orchestration and automation. Whether you have 3, 30, 300, or 3000 hosts, you can benefit from knowing the entire stack. Get comfortable with networking, scripting, applications, and cloud. Know why each matters and what the limitations are. You may never run into the limitations, but you need to know them.

It is as important to know why something is an appropriate solution or why it isn’t. That’s our responsibility to ourselves and to our organizations.

And to close, I don’t think that VMworld has jumped the shark as many have said. I think that it’s evolved.  I wrote a blog about why the shark jumping keeps coming up, and how the community members have evolved here.

Stay tuned for the VMworld Barcelona which will feature more on Photon and the EUC platforms most likely.
