First cruise review: Norwegian Epic March 1, 2015 – Western Caribbean

This has been sitting in my drafts folder since mid-2015, so the information in it re: UBP charges, menu contents, etc. are all outdated at this point, but I think it’s still a good representation of how our first cruise went. Suffice it to say, I need to be more timely with these – we’ve since gone on a Bahamas cruise on the NCL Breakaway in December 2016, and have a different Caribbean cruise planned on the Epic during December 2017. So even if there are some negatives here, clearly we’ve gone back so it can’t be that bad.

I’ll try and note in the article where things have changed.

In Which We Decide To Cruise

In 2015, Kayla and I got tired of the snow and wind and ridiculously cold temperatures in Southwestern Ontario, and decided to get away to a warmer climate. We’d been to BlueBay Villas Doradas in the Dominican Republic to do the all-inclusive resort trip with a few friends last year and while we liked it, we wanted to try something new before falling back to the same thing. We’d also discussed various Sunwing-promoted destinations flying directly out of YKF to Mexico, but the available resorts in our price range were either too new to have a decent amount of feedback, or had recently begun “focusing on a new concept.”

Then the idea of taking a cruise came up and we started looking. A few years ago in a hotel room in Prague, I’d seen a documentary that was pretty much an expose of the entire cruise ship industry. I managed to locate it after returning – it’s CNBC’s “Cruise Inc: Big Money on the High Seas” (2009).  It went over a cruise on the Norwegian Pearl, describing how passengers are basically just walking ATMs and that the cruise line is constantly running the numbers on every aspect of shipboard operations. The conclusion was that on the last sea day, the operator broke even for the cruise, in no small part to making up $21K in alcohol sales. Being shaken up and down for cash constantly didn’t really appeal to me.

Fix: WSUS Server Cleanup Wizard hangs/stalls when deleting unused updates

Side note: several years ago Kayla caught me talking in my sleep, muttering something about “you’ve got to check the boxes!” This is the actual dialog and process in question.

Full credit to Jeremy Jameson at MSDN. Posting in case the original disappears.

  • Run Server Cleanup Wizard with only the “Unused updates and update revisions” (option #1) box checked. This took about six hours on the server experiencing the problem:screen-shot-2016-11-22-at-11-32-29-am
  • Once finished, run the wizard again with only the “Unneeded update files” (option #3) box checked.
  • Once that’s finished, run the wizard with all the boxes checked.

RiteBite and Invisalign Review: Conclusion

Well, better late than never, but I’m currently in the process of cleaning up paperwork in the home office, and noted that RiteBite had given me a flyer asking for a Google review several months ago. So here’s a conclusion to the review series, which will be combined with the other content and sliced into bits and pieces for the less-verbose social media pages.

Completing the Program

Since last time I wrote, I went through about half of another series of trays with 7-day rotations. I specifically requested to have my treatment wrapped up about a week before my wedding in August 2016, and Dr. Luis and staff were very accommodating since this third set was effectively “finishing touches”. As part of the removal, I had permanent wiring bonded behind both my top and bottom teeth and was given a set of top and bottom harder, clear plastic retainers to wear overnight. One important point is that for the first two weeks, you’re expected to wear the retainers as close to 24/7 as possible, so you’re not “entirely” done. I obviously made an exception to this for the wedding.

A Few Nitpicks

The retainers are not ideal, to put a point on it. Their larger size (compared to the Invisalign trays) and increased rigidity triggers my gag reflex nearly every morning when taking them out, and I still run into similar problems with drooling on my pillow.

I also specifically requested the top permanent wire, and had to ask several times before getting a “yes” – several staff suggested that it wasn’t strictly necessary or had a higher chance of breaking. I wanted to ensure that with my financial investment, there was a “backup” in place to help the teeth from moving as much. The top wire’s presence is still noticeable when I close my mouth several months later, unlike the bottom wire. Both still have a distinct “pebbled” texture where the wire is adhered to the back of each row of teeth.

Despite asking for Google reviews as part of the “exit interview”, RiteBite seems to have several accounts under their name on Google Plus (1, 2, 3, 4, 5) and no link to the official Google profile from their website, nor any content on these pages. I was also disappointed to find that the Case Graphics section has disappeared from my profile since completing treatment.

Overall Results

The change has been quite impressive. It took slightly over a year and a half, I wasn’t seriously inconvenienced, and now that it has been paid off, I begrudgingly admit that it was probably a better personal choice than replacing the laminate flooring in the house or buying the same amount of networking gear.

Continuing the “Router rumble” with pfSense 2.3.2 and a FW-7540

Following up from my previous round of router testing, I managed to get a spare Lanner FW-7540 with an Intel Atom D525 CPU to test how my current pfSense 2.3.2 setup compared to an EdgeRouter Lite. The results were well below what I was expecting: the pfSense box topped out at 490Mbit in the 1MB test and was very spiky when looking at the netdata graphs.

The results file is also available if you’d like to look directly at the ab output.

d525_pfsense

Filesize Average Mbit/s Total Failed Requests Notes
10K 145.07 87 10K concurrency test only resulted in 49Mbit. No failed requests in 10, 100 and 1000 concurrency tests.
100K 421.71 4896 No failed requests in 10, 100 and 1000 concurrency tests.
1MB 489.96 3341 No failed requests in 10, 100 and 1000 concurrency tests.

This test fairly obviously shows a ceiling. For WAN connections of over 500Mbit, it looks like something beefier than an Atom D525 is necessary to run the NAT as anticipated.

I also ran some more informal WAN to LAN iPerf3 testing on direct connection (MDI-X), the EdgeRouter Lite and the pfSense/7540 combination to get some synthetic numbers:

Connection iPerf Result
Direct 941Mbit with no retries
EdgeRouter Lite 939Mbit with retries
pfSense/7540 829Mbit with no retries

Given how well the EdgeRouter Lite seems to perform for its price, and since it beats out the more general purpose hardware, I suspect I will be swapping out for an ERL or ER-Pro very shortly.

Replicating the Ars Technica “Router rumble” with a Ubiquiti EdgeRouter Lite

A friend and colleague of mine (Matt) and I have an ongoing discussion about over-specced gear for our home networks. Our core routers have been FW-7540s running pfSense (Atom D525, 4GB RAM, 4 Intel NICs) since 2013. pfSense offers a huge advantage over commercial-grade routers – I run dual WAN with failover based on ping, link, and packet loss, have extremely customizable DNS and DHCP, and can set up an OpenVPN server in just a few minutes. Matt and I also recently have had 500Mbit+ downstream connections installed, so it’d be good to know what hardware and software combination is “for sure” capable of utilizing the full pipe.

There have been a series of excellent articles at Ars Technica this year by Jim Salter that constantly get mentioned in our discussions:

Error during migration: MigrationPermanentException: Cannot find a recipient that has mailbox GUID ” error message when you try to move a mailbox in an Exchange hybrid deployment

Source: https://support.microsoft.com/en-ca/kb/2956029

  • Ensure the local user object doesn’t have an exchange GUID. From the local Exchange Management Shell:
    Get-RemoteMailbox <MailboxName> | Format-List ExchangeGUID
  • Get the GUID from the error message, or retrieve it from the O365/Exchange Online shell (connect as above):
    Get-Mailbox <MailboxName> | Format-List ExchangeGUID
  • Set the exchange GUID for the user from the local Exchange Management Shell:
    Set-RemoteMailbox <MailboxName> -ExchangeGUID <ExchangeGUID>
  • Force directory sync. Using the latest Azure AD Connect commands, on the server with the directory sync tool installed:
    Import-Module ADSync
    Start-ADSyncSyncCycle -PolicyType Delta
  • Monitor with “Azure AD Connect Synchronization Service Manager” GUI application if needed.

 

Error during migration:  MigrationPermanentException: Mailbox size 12.56 GB ‎(13,489,367,463 bytes)‎ exceeds target quota 2.3 GB ‎(2,469,396,480 bytes)‎.

  • If applicable to a single user, use ADSI Edit to set the “mDBUseDefaults” property to False on the applicable user object, then try again.
  • If database or organization-wide, use the Exchange Administrative Center to remove quotas for the database.

I have a migration batch that partially failed. Now I can’t get those mailboxes to migrate.

Sources:

Scenario: A migration batch was partially successful (one or more mailboxes in the batch migrated properly). The errors for the remaining mailboxes have been corrected. I’d like to start a new migration batch containing the failed mailboxes, but the batch bombs out with an email to the Exchange Online administrator. The batch online looks like it’s still migrating, but the CSV with the results that was emailed contains the following error messages for each account:

The user "user@example.com" is already included in migration batch "My Migration Batch Name."  Please remove the user from any other batch and try again.

In this case you need to remove user from migration batch using the Remove-MigrationUser cmdlet when connected to the Exchange Online PowerShell session:

  • Get the details of all users in migration batches, or get the details for the specific user being migrated:
    Get-MigrationUser
    Get-MigrationUser user@example.com
  • Remove the user from the migration batch. Use the additional -Force parameter if you aren’t running interactively.
    Remove-MigrationUser user@example.com
  • Clean up any migration batches that may still be in progress with the ‘already included’ error.
  • Create a new migration batch containing the affected mailboxes.

Fix: trying to overwrite ‘/usr/share/accounts/services/google-im.service’ installing kubuntu-desktop

I have an Ubuntu 16.04 desktop installation with Unity and wanted to try KDE, so I ran sudo apt-get install kubuntu-desktop. apt failed with the following message:

trying to overwrite '/usr/share/accounts/services/google-im.service', which is also in package account-plugin-google [...]

The original issue at Ask Ubuntu has several suggestions but none of them worked – any apt commands returned the same requirement to run apt-get -f install, which in turn gave the original “trying to overwrite” error message. synaptic also wasn’t installed so I couldn’t use it (or install it, as all other apt installation commands failed.)

I was able to get the dpkg database out of its bad state and continue to install kubuntu-desktop by running the following:

dpkg -P account-plugin-google unity-scope-gdrive
apt-get -f install

(Link to original Kubuntu bug for posterity: https://bugs.launchpad.net/kubuntu-ppa/+bug/1451728)

RiteBite and Invisalign, just over a year in

I’m just over a year in since starting Invisalign treatment with RiteBite Orthodontics – and here’s how things stand.

Positive Experience

I want to reiterate that I’m quite pleased with the experience I’ve had with Dr. Luis and RiteBite. Everyone at the Waterloo office has been friendly, professional and my appointments have always started on time. I feel like Invisalign was definitely a better option over braces. Even under the perpetually ticking clock of their Terminal Services-hosted dental software, everyone that’s put their hands in my mouth has done a great job.

Don’t you just love the graphics?

Another “Let’s Encrypt” post for nginx

I’ve replaced the certificate on this site with one issued by Let’s Encrypt and plan to do so for all clients (or enable SSL in the first place) as their domains come up for renewal, or other maintenance work is contracted. The big downside is a 90 day expiry time, which requires a service nginx reload at least that often.

I had no end of issues using the official client as it wouldn’t create the .well-known/acme-challenge files necessary to get the domain to validate (yes, I checked directory permissions.) Instead, Vincent Composieux has some excellent instructions on just using the certonly parameter inside a script.

Invisalign on my own dime: orthodontics in Kitchener-Waterloo

I’ve been meaning to write about my experiences with Invisalign and the orthodontic consultation and treatment process since I started investigating various options in July 2014. On advice from my dentist Dr. Reddy and her staff at King Street Dental, I received several referrals to orthodontists in the KW area, and did my own research into reputation, pricing and treatment options.

Before getting into the orthodontic part of the piece, I would definitely recommend Dr. Reddy. In my experience, she handles both routine and emergency dental work to a very high standard.

Initially, Dr. Reddy suggested that she could extract one or more teeth to correct crowding in my lower jaw, but also indicated that I should look at orthodontic treatment as an alternative.
