As you know, we offer a great integration with both Google Drive and Box, giving you the choice of using either of these cloud storage services when you sign up as a Kerika user.
For most people, the choice of whether to use Google or Box is often made by their employer, whose IT departments may have already developed a cloud strategy for their organization.
For a small number of people, particularly those in organizations that haven’t committed to a particular cloud strategy yet, they do have the choice of using either cloud service, or even both.
So, what happens if you have the same email address, e.g. someone@example.com, and you set up a Google ID and a Box ID that use this same address?
You could end up with two different Kerika accounts that use the same someone@example.com ID: that’s because each sign up, from Google and from Box, takes a different path into Kerika.
This is not a great situation to be in, and we certainly don’t recommend it, but the software does try to behave well when confronted with this situation.
If another Kerika user invites you to join her project team, the invitation will show up in both your Kerika+Google and your Kerika+Box account — and in your email, of course — but when you try to accept the invitation Kerika will check to make sure you are logged into the correct service.
Here’s an example: Jon, who uses Kerika+Google, invites Arun to join one of his projects. Arun happens to have both a Kerika+Google account, and a Kerika+Box account, but Jon doesn’t know that — and he shouldn’t have to care, either!
When Arun sees the invitation, he happens to be logged into his Kerika+Box account:
Invitation received on Kerika+Box account
But when he tries to accept the invitation, Kerika checks to see whether Arun and Jon are both using the same cloud service, and discovers that Arun is logged into his Kerika+Box account and not his Kerika+Google account:
Prompt to login to Kerika+Google account
So, Kerika works behind the scenes to help Arun sort out his two accounts.
Using Kerika with Safari in “Private” mode can result in some odd behavior, and that is entirely due to the way Safari works — it’s pretty much out of Kerika’s control :-(
The underlying problem is that Safari doesn’t allow Web apps to use local storage (cache) when the browser is in “Private” mode.
Since Kerika relies upon local storage to provide a smooth, real-time effort, this can compromise the user experience if you use Safari in Private mode.
We are often asked how the Kerika team itself uses Kerika, and we freely share this through demos we have done in person for potential customers and at various events. For those who we haven’t met in person, here’s a blog post instead..
1. Kerika runs on Kerika.
Pretty much everything we do, from the smallest, tangential effort to our main product development is done using the Kerika software.
(It shouldn’t surprise you to hear that, given that we are a distributed team ourselves — spread out between Seattle and India.)
2. No email, limited phone calls
In fact, we gave up using internal email back in Dec 2013. (Email sucks, and Kerika is the smarter alternative to spam.)
Because our team is spread out over 10,000 miles, we do occasional phone calls, using Skype or Google Hangouts, to discuss product strategy, but we don’t have daily phone calls as a matter of routine.
We have a phone call only when there is something substantial to discuss, never to catch up on routine status. In other words, all our phone conferences are about interesting topics, like “What do you think about this idea…?” or “I met a customer today who brought up this problem…”; never about “Where are you with Task X?”.
Kerika keeps us in perfect sync across these 10,000 miles on all matters of routine status and project management, so our phone calls are all strategic in nature.
3. Scrum for Product Development
We work with a 2-week Sprint Cycle for the most part, although we have occasionally deviated from this — never with great results, so sticking to the cycle is usually a good idea!
We capture all of our product ideas and feature requests in one large Scrum Board, which we call, simply, Product Planning.
This board organizes our ideas into various buckets, like Valuable for Enterprises and Valuable for Individuals:
Product Planning buckets
You might notice that the Backlog column is relatively small: only 54 items. That’s because not everything in the other buckets is ready to go into the Backlog, either because a feature isn’t well defined enough, or it isn’t considered important enough to deal with in the short-term.
(We have a lot of ideas that sit and gestate for months, even years!)
It’s also worth noting that the Trash contains 62 items: this means we reject as many ideas as we pursue!
4. A Shared Backlog
As ideas for various features get prioritized — and, more importantly, defined clearly enough to be analyzed in detail by our developers — they get moved to the Backlog.
This backlog is shared by all the individual product development Scrum Boards:
Product Planning process
(And, by the way, the screenshot above is from a Kerika Whiteboard that we use to map out our product planning process.)
Each Sprint is organized as a separate Scrum Board, pulling items from the common Backlog.
As items get done (or not, as the case may be), the Backlog slowly shrinks over time.
But, as ideas for new features gets firmed up on the Product Planning board, this keeps feeding more stuff into the Backlog. So, the net result is that our Backlog has remained the same size for years: about 50-60 items.
We have been doing this for a while now, and are currently wrapping up Sprint 55, with each Sprint taking at least 2 weeks, and several taking 1 month to complete.
Here’s an example of one of our Scrum Boards:

5. Kerika’s Smart Notifications
So, if we are a distributed team that doesn’t use email, and not that much phone either, how do we keep up with what’s happening? The answer is: Kerika’s smart notifications help each of us easily keep track of changes taking place across literally hundreds of cards each day.
Here’s an example:
Smart notifications
At a glance we can tell that this card has
Moved
Has a new due date
Has new attachments
Has new (unread) chat messages
And, unfortunately, needs rework :-(
These smart notifications replace dumb email with a much more efficient mechanism for keeping everyone on the same page.
6. The Development Process
If we open up one of these cards, we can get a glimpse of the Kerika development process. Let’s start with the chat thread on this card:
Example of new chat
This chat shows a typical interaction between a junior developer and a technical lead: after writing the code for a particular feature, the developer has passed it on to the tech lead for code review.
The code review itself is attached to the card, as an attachment:
Adding code review to a card
For each feature we develop, our engineers create a small work plan that outlines their design thinking.
This design/work plan is a critical artifact for good software development: it ensures that people can review the work more easily and effectively, and it also provides a reference for the future — if ever a bug is found in this particular feature, we can go back to the work plan to see where the design flaw may have originated.
The code review is typically very short, and attached (in this case) as a Google Doc:
Example of code review
7. Card History
Each card in Kerika keeps track of its own history, which makes it easy for a distributed team to keep track of everything that happened. Frequently, a number of changes may have taken place on a single card during a workday, and someone who is 10,000 miles away is also about 13 hours away in terms of timezones, so the history feature is useful for understanding all the changes that took place when you weren’t looking.
History of the work
So, that’s a typical card, on a typical board. And, in a typical 2-week Sprint Cycle, our development team handles 175-200 cards!
We love Kerika, not just because we have built it, but because it makes our distributed team so very effective!
If you have a premium (i.e. paid) version of Google Apps running in your organization, your Google Apps Administrator will need to authorize Kerika for your domain, before anyone within the organization can use Kerika.
Here’s step-by-step directions on how to do this:
1. Go to your Google Apps Admin console.
Go to http://admin.google.com, and log in as the Google Apps Administrator for your domain:
Start at Google Admin console
2. Click on the “Apps” button.
This is where you can manage all your Google Apps, as well as third-party apps like Kerika that integrate with your Google Apps:
Click on the Apps button
3. Go to “Marketplace Apps”.
Google separates out its own apps from third-party apps, so you want to click on “Marketplace Apps”:
Go to Google Apps Marketplace
4. Click on “Add Services”.
All the apps you currently have installed for your domain will show up here (in this example, none have been installed so far); click on the blue “Add services” link:
Add services to your domain
5. Search for Kerika.
Search for “Kerika” in the Google Apps Marketplace:
Search for Kerika
6. Click on “Install App”.
Kerika’s entry will show up in your search results; click on the blue “Install App” button:
We have been one of the last jazzy Web apps out there that was still running on Internet Explorer 9, but that’s going to change: with our next release, due in a month or so, we will be asking Internet Explorer users to upgrade to IE10 or later.
The main reason for this change is that all “modern” browsers — and IE9 qualifies as “modern” only when it stands next to IE8 — do a lot of work within the browser itself that Kerika currently does: stuff like managing and manipulating the DOM structure of the Kerika application.
This means that the Kerika client-application — the bit that you actually see and use in a browser — is unnecessarily complicated, and somewhat slower, than it needs to be, because we are doing some work that IE10+, Chrome, Firefox and Safari all do within the browser itself.
Dropping support for IE9 will enable us to provide a faster user experience, with less complexity in the code.
Some of our Kerika+Box users have been complaining about the number of email notifications they get when new projects are created: this has to do with Box, rather than Kerika, but it’s helpful to understand what’s going on, and what you can do about it.
When you create a project in Kerika, Kerika creates a dedicated folder for the files that will be used in that project. This folder is shared with whoever needs access to that Kerika project.
Every Kerika user can set a personal preference: you can choose to share your new projects with your account team automatically when they are created, or just with people as and when you add them one by one to a Kerika project. By default, this is set to “share with account team” since this helps people discover new projects within their organization.
One downside of this: whenever you create a new project team, especially if it owned by a service account, a new Box folder will get created for this project and shared automatically with everyone who is part of that account.
This was resulting in way more emails than anyone wants to see, so we have made a change in the way we work with Box:
When people get added to a Box folder, through Kerika, they will no longer get an email notification.
However, the Account Owner will still be notified; there doesn’t seem to be any way around this.
And who are the “right people”? Well, anyone who is assigned to that card will get the chat sent as email, and Project Leaders can optionally get chat pushed to them as email as well. Everyone else can catch up with the chat when they visit their board.
When chat messages get pushed to you as email, you can reply to them just like regular email (all you need to do is a simply “Reply”, not a “Reply All”).
But, don’t go crazy with emoticons! Most smileys work OK, but not every emoticon will get encoded correctly (using UTF-8).
So, it’s natural to be happy when you are using Kerika, and it’s OK to smile while you work, but don’t use too many strange emoticons in your email replies!
When you are drawing on a canvas, either for a Whiteboard project or a canvas that you have attached to card on a Task Board or Scrum Board, Kerika gives you some basic shapes you can use to sketch out your workflow, process diagrams and other ideas:
Drawing shapes on canvas
You can connect shapes using lines and arrows (single- and double-headed), and as you move the shapes around, the lines and arrows automatically adjust so that they terminate properly on the edge of the shape.
It turns out we had a bug where the lines didn’t properly connect to the very edges of diamond (rhombus) shapes:
Problem with lines on edges of diamonds
This was quite literally an “edge case” (sorry about the pun): when the line travels along the edge of the diamond shape, as the shape is moved by the user, a function is used to calculate the exact intersection of the line and the shape.
(This function is the only proof we have ever seen that anyone actually needs to use trigonometry in real life.)
When the line travels right up to the corner of the diamond shape, because the line is connecting the diamond to another shape that is of precisely the same height and width, and the two shapes are aligned perfectly (either vertically or horizontally), the function returned two possible intersection points.
We have fixed this problem in our latest release. It should make for neater looking flowcharts!
Right now, the Kerika user interface is entirely in English, but we have users worldwide and many of them use Kerika with other languages, e.g. Greek, Japanese, Korean, etc.
When you export data from a Task Board or Scrum Board that includes non-English characters, the foreign characters are actually preserved correctly as part of the exported data, but if you need to then import data into some other program, like Microsoft Word or Excel, you need to make sure the other program correctly correctly interprets the text as being in UTF-8 format.
WHY UTF-8?
UTF-8 is a coding standard that can handle all possible characters, so it works with languages like Greek, Japanese, etc. which don’t use the Roman alphabet.
For a long time now, UTF-8 has been the only global standard that works across all languages, because of its inherent flexibility in handling different character sets.
When you do an export of data from a Kerika Task Board or Scrum Board, we create the CSV files in UTF-8 format, and include what’s called the Byte Order Mark (BOM) in the first octect of the exported file.
Including a BOM is the best way to let all kinds of third-party programs know that the file is encoding in UTF-8: it’s a standard way of saying to other programs, “Hey, guys! This text may contain non-English characters.”
And for the most part, including a BOM works just fine with CSV exports from Kerika: Google Spreadsheets interprets that correctly, Microsoft Excel on Windows interprets that correctly, but not…
EXCEL ON MACS
Many version of Excel for Macs, going back to Office 2007 at least, have a bug that doesn’t correctly process the BOM character. Why this bug persisted for so long is a mystery, but there we are…
The effect of this bug is that an exported file from Kerika, containing non-English characters, will not display correctly inside Excel on Mac, although it will display correctly with other Mac programs, like the simple Text Edit.
There’s not much we can do about this bug, unfortunately.
THE TECHNICAL BACKGROUND TO ALL THIS:
BOMs are used signify what’s called the “endianess” of the file.
Endianess is a really ancient concept: in fact, most software developers who learned programming in the last couple of decades have no idea what this is about. You can learn about endianess from Wikipedia; the short summary is that when 8-bit bytes are combined to make words, e.g. for 32-bit or 64-bit microprocessors, different manufacturers had adopted one of two conventions for organizing these bytes.
For Big-Endian systems the most significant byte was in the smallest address space, for Little-Endian systems the most significant byte was in the largest address space.
(If you have a number like 12345, for example, the “1” is the most significant digit and the “5” is the least significant. In a Big-Endian system this would be stored as “1 2 3 4 5”; in a Little-Endian system it would be stored as “5 4 3 2 1”. So, when you get presented with any number, you really need to know which of the two systems you are using, because the interpretation of the same digits would be wildly different.)
(About a dozen years ago Joel Spolsky, former PM for Excel, wrote a great article on the origins and use of BOM, for those who want to learn more about the technical details.)
Why this affects Kerika at all? Because when you do an export of cards from Kerika, the export job is run on a virtual machine running on Amazon Web Services.
We have no idea what kind of physical hardware is being used by AWS, and we are not supposed to care either: we shouldn’t have to worry about whether we are generating the CSV file using a little- or big-endian machine, and whether the user is going to open that file with a little- or big-endian machine.
That’s the whole point of using UTF-8 and a BOM: to make it possible for files to be more universally shared.
We used to have a feature where you could add a URL to a canvas or Whiteboard, and then choose to show that either as a regular bookmark, or as an embedded IFRAME.
We are dropping the embedded IFRAME feature, because most of the time it doesn’t work, and even when it does work, it’s not a great feature to have:
You can only IFRAME a website if that site lets you. And, increasingly, most sites don’t.
IFRAMEing a third-party website on a Kerika page is a potential cause for worry, from a security perspective, because we are letting that third-party website right into the Kerika page.
