I’ve just seen CBT Nuggets video on YouTube entitled “How to Transition to DevOps” and though I cancelled their subscription quite some time ago it sparked my interest and made it very tempting to subscribe again (if only not my financial and time budget constraints).
I really like expressive quotes and explanations which use analogy and one from this video which I really liked can be found below. Along with some basic theory on what is and how to approach DevOps in this video Shawn Powers shows little demo which demonstrates how to use Chef recipe for configuration management, and next goes the following conclusion:
“…configuration automation is awesome example of how DevOps is kind of taking two different worlds the world of installing packages and uploading files and code which allows us to programmatically solve problems and put them together kind of like peanut butter and chocolate goes together to make a Reese’s Cup and it’s you know awesome it’s better than the sum of its parts…”
Nice. And I also need to try these Reese’s Peanut Butter Cups now even if it a bit violates healthy diet 🙂 Think it goes well with coffee and IT training videos (if consumed in limited amounts).
I just looked at DevOps courses available at CBT Nuggets at the moment and though it seems there is no DevOps overview/general course available so far they already have courses on specific tools (Puppet, Chef, Docker, Ansible).
It has been a while since I written anything on my blog – was a bit busy. Then I decided to write a tiny review of this book but fell under the spell of Steven Sinofsky‘s long form write ups and as a result this tiny review turned into something too big and I was trying to finish it for way too long. I end up finishing this abruptly and posting using truly Bill Gates’ approach of “get it out there, fix it later”, as sticking to “keep it secret till you make it perfect” Apple approach is way too difficult to adhere to. So if anything is wrong here I’ll edit it later 🙂
I’ve recently finished listening Audible’s audio-book “Glock: The Rise of America’s Gun” by Paul M. Barret and it was so good that I can’t help writing (a bit) about it here on my blog. I have quite broad range of interests without allergy to go deeper in any number of narrow topics, so on my ever-growing to read/to listen list there are always very diverse books, with topics ranging from economics and linguistics to IT, to history and I never know what else.
From that vast array of topics two have special importance for me: philosophy and history. I just keep noticing that way too many people dismiss first as something you can read/listen only after smoking some weed (I almost quote one of my former school classmates here) and the second as something of a little value and relevancy to our present-day life. It makes me a tiny bit sad to see those disciplines neglected and grossly underestimated. Seriously, the negligence and ignorance about each of these domains is by itself a topic not for a blog post, but for an essay or even a whole book ? What could be more important to slow down and to think about “how do we think about things” and “what is worth to think about in the first place” along with “being acutely aware about what has been done and tried before you”? I hardly can name anything more important I think…
Anyhow getting back to the Glock book, it was one of those which just caught my attention somehow (back then I haven’t had any interest in guns beyond general vague subconscious man predisposition to all things military), and it then waited for something like 5 years before I decided to listen to it. Essentially as many of other books in my Audible wish list it landed there thanks to serendipity and maybe some clever Amazon recommendations algorithms. And as it happens sometimes with the book turned out to be absolutely brilliant and it was just waited for the right time to be listened to (in this case it means some experience with pistol practical shooting and Glock pistol). Another example of the same random-perfect choice for me was “The Language Instinct – How the Mind Creates Language” book by Steven Pinker– this book too was sitting in my wish list for about 5 years and was added there instinctively, and despite I was interested in linguistics when I put it on my wish list, while it was sitting there I managed to learn a lot of stuff about the topic, took some Coursera courses which introduced me to some of the linguistics problems, and then I finally got around that book and it was just “wow” and “why I haven’t listened to it earlier” and “it is a book which eligible to re-read/re-listen many times”…
Looping back from randomly selected books and importance of history to the Glock book. It is one of those non-fiction books which introduce you to the history of the specific topic with great details, and I strongly believe when such books are written by informed person with keen interest to the topic, almost any topic can be really fascinating to dive in. In this case book has it all: history of engineering and enterprise, some political and cultural background, corporate rivalry and person/character evolution – there are so many facets covered in the book which make you understand a lot of things better (if you wish to) or merely enjoy fascinating unfolding of the great story (and as it often happens, true stories turn out to be way more exciting and unpredictable than most works of fiction). I won’t be writing coherent review of the book, but rather list some of my take-aways from it.
On good product. This book is in itself an example of good product design, where even a name (for informed person) designed to spark your interest and buy the book. I mean the title “The Rise of America’s Gun” combined with black Glock pistol on a white background should spark in you an interest as to how Austrian made pistol from old Europe can be an America’s gun, meaning a gun of a country where guns culture is a part of a nation´s psyche and where some other epic names used to reign supreme? Surely you know that gun which won the west? And it wasn’t Austrian one, right? So this book is artfully designed product about another good product which appeared out of nowhere (not exactly of course) and won the market which it possibly it never could have dreamed of, and it won it in a big way. But to understand how you need to know the history which will tell you that everything was important: right timing for entry to the market, a bit of luck, huge amount of controversial (but free for the company) publicity, importance of designing from scratch – good story about good product can teach you a lot about what is important for products, and this knowledge is transferable, meaning that it can be relevant not only to pistols design and manufacturing but, let’s say, for modern day software products or any other products. So I’ll just try to highlight some points from the book which show importance of learning from history and how it can be still relevant.
On engineering. Designing from scratch is something you should do to really innovate. And it does not mean you throw away history/what has been done before you – on the contrary you have to critically review with a pair of fresh eyes and then design from scratch. Before starting development of his gun Glock bought tested and disassembled number of popular guns available on the market: and come to conclusion that all of them unnecessarily complex (too many parts).
What was really new for gun design is the following:
Pistol was designed for complete production on CNC (computer-controlled) tools = lower production cost. This was possible as Glock didn’t have an existing production plant and he was able to build one with this in mind
Pistol frame was made out of light, resilient, injection-molded plastic. And it is first commercially successful firearm which was designed with such material. Glock had begun learning about the material when he bought an injection-molding machine to make handles and sheaths for the military knives he produced in his garage. Glock hired former employees of a bankrupt camera manufacturer who brought advanced injection-molding and plastic-design skills. This allowed Glock pistol be remarkably strong and resistant to corrosion, a major problem with traditional steel guns. And light too. Bug main reasoning behind this design was getting savings on raw material and labor and distinct ergonomic advantages over gun cobbled together from blued steel and walnut. There were earlier attempts to use polymer frame which had not had any success due to design shortcomings (American Remington Nylon 66 rifle and the German Heckler & Koch VP70 pistol)
Glock worked with shooters and wooden pistol models on a early design stages to decide on grip-to-frame angle which allows to point gun “instinctively” – and initially it was defined as 22 degrees. Angle was a bit reduced later but up to now unconventional grip-to-frame angle of Glock makes difficult to shooters to switch to any other pistol (majority uses other angle).
All established market players were all intheir product-market fit (PMF) stage – they just were to attached to their existing gun designs and in PMF stage your business is about extracting more money from existing product – there is neither time no motivation for building different/new product. It is not only “we always done it like that” and “we cannot do it differently” mindset it is also “we have not tools for that” syndrome.
Innovation through removing features. One thing which was crucial for this product is taken away an essential feature and throwing it away, transforming absence of this feature into feature in its own right. I haven’t done any research on this, but I bet external safety trigger was once innovative product feature and selling point for some other gun. We can see this rather a lot in software products (especially as they move to the cloud) – we gradually lose some features we can fiddle with but after a while embrace the increased simplicity and efficiency of that, and the same happens with hardware products (think of mobile phones and bold move of throwing away hardware keyboard).
So Glock was able to sell idea of removal of external safety trigger (though technically it has some sort of 3 step internal one, but from usability POV there is just a trigger and no safety trigger) – it was major selling point as it introduced simplicity of use.
Your strength is your weakness too. Book brilliantly illustrates problem of fit to market stage – old gun manufacturers were busy extracting money from existing product designs with no ability to change them. Unfortunately even zeal of product fans and legendary brand image stop supporting you if there is new better product addressing clients’ needs.
And it is not only syndrome that we did it like that all the time, so we can´t change it, it is also “we don’t have tools” syndrome.
On time to entry (to the market). Glock not only won contract for Austrian army he also been in time (without any plans of doing so) to address concerns of American law enforcement organizations which were prepared to embrace necessity of moving away from west beloved revolvers to different gun. There were reasons for those concerns, in particular incident known as 1986 FBI Miami shootout which eventually lead to the process of searching for new gun for FBI (1987) and later for other law enforcement agencies. Long story short that incident show inability of revolvers to compete with semiautomatic weapon in the hands of professionals. 4 minutes of shooting, 8 FBI agents armed with revolvers and some shotguns VS 2 criminal, only one of them having Ruger Mini-14 semi-automatic riffle which was sufficient to do suppressive fire.
On shaping client needs. Shape your client needs (Apple way) or at least talk to your clients early in design stage. Nobody asked for plastic pistol, and even once they get it some were to attached to their revolvers considering Glock an ugly gun – that has changed after it was adopted by professionals (publicity matters) and other shooters – then everybody discovered usability, efficiency and gun acquired its own cachet of best gun, instead of “ugly” people started to call its look “futuristic”… From ugly duckling to the pistol of the future.
On publicity. Publicity matters. Sometimes even not a very good one. Glock received a lot of free publicity on different occasions – congress hearing related to it being terrorist gun invisible for metal detectors and some completely irrelevant descriptions from Hollywood action movies which cemented gun presence in popular culture. Most of the publicity was free of charge and some was bad, but as Bill Gates used to say “whatever they say about us it is always better than not saying anything about us” (not 100% sure on exactness of quote but I believe it is something from MSFT early days).
Maybe someone still remember that epic description of non-existing Glock 7 in Die Hard movie too… The one where neither gun model nor single word in its description provided is true, but main thing that everybody talking about your brand and you are not paying for product placement ads.
On brand storytelling and company message. “Glock perfection” message and personal inventor/businessman legend was formed by some accidents, then supported, developed and shaped by company and its fans. At some point it just start living on its own. So if you as a business don’t have one you’d better work to have it early on and have it right – it may work for you later.
From humble beginnings to the arrogance of success. I believe the Glock as a product centered business is in its product-market fit (PMF) stage, but as it always the case with tangible and software-less product such periods are far longer than for any software or software-enabled/smart product. But still we may expect that somebody will come up with biometry based safety trigger totally blocking ability to fire the pistol to anyone but its legal owner or something that decrease complexity of a gun even more (we still have noise, moving parts and metal parts). But interestingly for Glock pistol and probably for most of the modern pistols in general, almost every remaining issue to address can be sold and believed by many people to be a feature they want to have and keep. Though in retrospect we may see that being big and cool looking, and surrounded by legends even, have not saved revolver(s) as a product – it was superseded by semi-automatic pistols and Glock had become just early entrant to the market which now enjoys status of perfect reputation and seemingly never ending PMF ?
If we look at the personal evolution of Gaston Glock we may also see that he is changed quite a lot from a timid engineer to more flamboyant person with different lifestyle and demands. But let personal things be personal.
On corporate intrigue and creative accounting. This book covers unsuccessful assassination and I would say that it adds to the overall story twists and dynamics you normally expect to see in fiction movies rather than in history books… Though one would say you can expect than when there guns and a lot of money going around… There is nothing funny when such things happen in real life but nonetheless the way it happened reminded me that fight scene from 2004 Punisher movie for some reason…
And just to conclude, or to address people who tend to scroll down and read final paragraph only: this is a fantastic book which can entertain (education and thinking is always optional nowadays) and contains some surprises and unexpected twists. For me it was really interesting to know more about Glock pistol and its business and development story. Just before I listened to this book I tried Glock 17 on a shooting range right after using heavier, larger caliber Tanfoglio Limited within the same training session and I should tell that now I know what features of the Glock explain my immediate results improvement.
P.S.Tanfoglio is a beautiful, high quality pistol, pleasant to hold but it is still an example of that harder trigger pull resistance and larger stopping power even in highest quality does not provide you with benefits of an easy and consistent results which you can get with light trigger (and light weight) pistol which just makes it easy (maybe even dangerously easy) to shot.
P.P.S. I can be wrong about trigger pool resistance though – geeks can read up some specs. Update May 2018: Recently I tried again both Glock 34 and CZ Shadow – and indeed CZ has super easy trigger if compared to Glock where you need to put more effort while pressing it because of “built in safety”.
P.P.S. For those who found this post strangely incongruous with normal topics of my blog posts be sure to wait for the next one about pottery (no it won’t be considered as something you can shot at 🙂 ). I’m really have plans for this post stay tuned.
I’m currently doing a bit of revision of 70-410 content going through “Microsoft Windows Server 2012 70-410 with R2 Updates” training by Garth Schulte. First of all I already passed 70-410 exam and did 70-410 course by James Conrad, but just to take a break before 70-411 I decided to review 70-410 content + go through 70-698 CBT Nuggets course and take an exams on Windows 10 (yes it counts as a pouse before 70-411).
Few words about updated 70-410 training by Garth. First of all it is fully designed with R2 in mind (James Conrad’s course was pre-R2 + some R2 modules added later) so you can’t find there gotchas and detours related with hiccups related with recent release of a product, instead as it covers stable and current release you will find there well structured up-to-date content and as one expect from Garth well covered PowerShell side 🙂 I also like very good slides summarizing key facts you have to memorize before exam – they provide you with compressed knowledge (I guess I stole getAbsract slogan here 🙂 ) you need before taking your exam. Some examples:
Those slides are just great to review before exam (so it could be a good idea to save some screenshots as you go through the course).
Good job Gath 🙂 Once I done with this training and my Win 10 exam I will be focusing on 70-411. And I’m just wondering how do I inject TCF exam and preparation for it in my schedule…
I’ve recently took exam 70-741 which is currently still in beta. I heard some feedback that this exam is quite tough, and honestly giving the fact that sub-net calculation skills tend to fade away without regular practice along with “great constants” (especially new set of IPv6 prefixes and other things you have to remember) I expected to be the difficult one.
Though after watching George Dobrea’s (@gdobrea) 70-741 preparation session recorded at TechEd NA I realized that I rather like practical focus on the exam – much better have network only stuff in one exam instead of having it dispersed across all the other exams in tiny nuggets as we have it in previous generation of certification exams from Microsoft. I really like the way they structured it now, and even early retake of 1 exam requirement is rather good/expected.
After taking beta exam itself I would say that I really liked it as question are really practice focused with short and concise possible answers and really test both your understanding of how it works as well as how to work with it (PowerShell/GUI).
I’m not sure whether I passed or not (for beta exams results being sent to you only after release date and only if you passed this exam) – but overall I didn’t feel like I failed despite plethora of questions about new things and some old things I didn’t remember well enough. Examples of things exam touches on which require revision for me are TrustedAnchors DNS zone, IPAM in general, DNS scavenging, root DNS server and Network Controller.
And just one more observation: The way MSFT orchestrates their product launches for last three product generations or so is really remarkable example on how to do it for any software company. They have it all: well before fancy launch events there is a work and engagement with community and early adopters, exams, training courses and books are prepared to be published just around the release date and by now already traditional free ebooks “Introducing …” available well before the release date clearly communicating selling points and positioning of product (touching on technical topics quite well but mainly giving you a big picture). Probably not any software company has that scale to afford all of this, but if you are vendor of enterprise grade software with established client base you may learn how to do launches from Microsoft – probably no surprises here, at the end of the day this is a company shipping software products since November 1985 release of Windows 1.0 – surely they know how to do this. But by now they really achieved remarkable mastery in product launch process which I can’t help noticing.
When your work is focused on specific product and services around it (does not matter if you in development, support or sales team of product centered organization) the most rewarding thing is to see real-world examples of how your product is applied in practice by clients. It is even better when it was implemented in such a way that client does not mind to share their implementation story with wider public in a video format. Really good to see such examples of how K2 really works for business.
Fozzy Group was able to built K2 based portal automating such things as contracts management, specification management, supply schedule management, sales forecast and score card just in one year. I don’t think you can see such BPA go-live dynamics with conventional code-heavy custom development as well as with some major (semi-)specialized products which end up being adjusted/customized for years (incurring high consultancy fees in the process) before business is able to go-live with them.
Amazing example from retail area which to my mind one of the activities where automation can bring great and measurable benefits. IMO most of the retailers still underutilize technology to its highest potential, but I hope we will see some changes as time goes by.
