If you are in the data science world, Scala is the best language to work with Spark, the defacto data science data store. I think that is really the main likely reason I would ever recommend Scala. Another reason is if you already have a team of programmers familiar with functional programming, e.g. they all have years of Haskell experience. In that case, I definitely think Scala is a superior and faster-growing language than Haskell and that picking up Scala after Haskell should be quick.
It does everything I want it to do without being too hard to use. The software is very powerful and has many options for apps, templates, and other things. We use it as the TV in our lobby, so we mostly show welcome messages, the weather, and video uploads from Vimeo and Instagram. Really easy to use, so I only have to spend a few minutes a week updating it. I make sure that all of my clients welcomes and other content play on the right day by scheduling them ahead of time. Give it a try and you will not be disappointed.
Excellent customer service. Each staff is very knowledgeable about the product and eager to assist. Very quick resolution of concerns.
In addition to the live weather function and the option to insert videos such as advertisements for our website, we can also display our instructional programs.
Love the flexibility around customizing the content.
The built-in compiler, scalac, is sssssssssslllllooooowwwwww. I mean like, if you thought the Java compiler was slow, try Scala! The default compiler on my 12k line codebase takes 4 minutes to compile from scratch on my i7 quad-core machine. This can be mitigated through the paid solution of Hydra which compiles your code in parallel. Unfortunately, it's quite expensive and your legal department or finance department may not approve of it. But if they do, for me, it reduced my compile time down to 80 seconds, much more manageable.
Scala is not going anywhere and support for it is slowly dying. This is the main reason I would not choose Scala for my next company or project. Important Scala libraries such as secure social (which is used for OAuth, a major requirement of every web app) are hardly maintained. Another library that suffers from lack of updates is Slick, the database mapper. There aren't enough engineers working on it to even provide support for the new features that came out in Postgres 9.0 (e.g. JSONb). There is simply not enough of a community to drive Scala forward and keep 3rd party libraries up to date as Java world does it.
As a corollary of a stagnant community, hiring Scala developers is hard as well. Of the 30 backend engineers we've hired, only 3 came in already knowing Scala. And as I will mention below, this is a BIG problem because learning Scala is really tough.
The learning curve for Scala is very, very steep. Anecdotally, I came into my current company with strong Java experience. Java is the closest language to Scala but it took me 6 months before I stopped needing to pair program on easy tickets. It doesn't help that Scala has some weird syntax like Map[A, +B] and that it forces you to do functional programming.
A few of the templates are difficult to modify or have restrictions on what may be added. During the holidays, for example, there are just a few photographs available. If you have a lengthy name, some of the birthday templates might be difficult.
When the gadget doesn't operate, we have to reset it at least twice a month.
The other drawback is the website's lack of speed / responsiveness at times.
The customer service team is very responsive and usually returns calls or emails within a couple of hours of placing a request or inquiry. Just about every rep I've spoken to has been very thorough and helpful, walking me through each problem and explaining the solutions in a way that's easy to understand.
Negative: slow engineer onboarding. As I mentioned before, it took me 6 months to get up-to-speed on Scala and didn't need to bother more senior Scala engineers anymore for help with every ticket. That's hundreds of hours I wasted of myself and other engineer's time.
Positive: thread safety, no concurrency bug. The ROI on this one is really hard to calculate, but I do believe Scala has saved me hundreds of hours over the past few years by allowing me to never have to worry about deadlocks or race conditions. Scala is simply so safe we've never had race conditions within the JVM before.
Negative: third-party libraries aren't maintained so we have to fork and update them ourselves. As I mentioned before, we use Securesocial but it stopped receiving updates and there is simply no alternative to it. So, we forked it and put an engineer on it for a month to get it back up-to-date. What a waste of his time!
It is much simpler to convey a message to all of the employees of the organization if it is shown on the television in a common area where they may see it on several occasions during the day.
It has also been of great use to us in personalizing security training invites for our customers, and the reaction that we have received from them has been really positive.
truDigital is a user-friendly platform that doesn't break the bank. In addition to that, their support for customers is exceptional. We could not have wished for a more fruitful collaboration than the one we had.
