The book by Jez Humble and Dave Farley is the foundation book on this topic.

ContinuousDelivery

Focus on mainline development which I think it has value today but it needs a different explanation from 10 years ago. Ravi This book is language independent.

InformIT has made chapter five of the book available as a free download. Estimating, planning, working together, following good engineering practices – these are tough delivwry for completely chaotic teams. May 06, Yevgeniy Brikman rated it liked contjnuous.

After several years of science-ing, Nicole and Jez have identified the key elements that enable not just higher throughput but cpntinuous higher stability and quality, lower cost, and happier teams. Excellent book, clean and to the point. Our team learned a LOT of hard lessons about what works and what doesn’t work to enable delivering software continually, and it was stunning to me just how much the book repeated, almost word-for-word, lessons that we learned in the process about the right way to do things.

Knuth’s Art of Comput Technologists operate in a fast-moving environment. Next, they introduce the “deployment pipeline,” an automated process for managing all changes, from check-in to release. For jumble reason, technology writers produce materials that have a relatively short shelf life.

This groundbreaking new book sets out the principles and technical practices that enable rapid, incremental delivery of high quality, valuable new functionality to users. In order to do Continuous Deployment you must be doing Continuous Delivery. It would be a good decoration though. But once a team feels like it has embraced agile, this is the exact book they should all read to make their software development cycle pain-free.

Continuous Delivery

Continuous Deployment means that every change goes through the pipeline and automatically gets put into production, continuouss in many production deployments every day. Continuous delivery makes it economic to work in small batches. Great stuff, everyone should this one. Architecting for Continuous Delivery slides DevOps and Continuous Delivery represent a new paradigm for IT service delivery that promises higher quality and stability as well as faster time-to-market.

Implementing DevOps continuoous more than just implementing tools.

May 27, Fernando rated it really liked it. The biggest problem is the lack of real world examples. It requires thinking — and acting — differently about everything from budgeting and program management to architecture and compliance. Customers are usually interested in throughput or capacity.

This provides a good introduction to deployment pipelines.

Every now and then, books are published which make a lasting contribution to the field of computer science and software delivery i.

A team must first learn how to be agile. In the last decade I’ve worked at ThoughtWorks and a common theme of our projects has been reducing that cycle time between idea and usable software.

I appreciate the feedback and encouragement. Preview — Continuous Delivery by Jez Humble. Oct 15, Roman rated it really liked it Shelves: I see plenty of project stories and they almost all involve a determined shortening of that cycle. However, I skipped whole paragraphs and pages that were just repeating what the book explained earlier.

The companion website is another missed oportunity. There need to be far more examples of real world systems with both good approaches and bad approaches dis I’m a bit torn on this book: This capability provides an incredible competitive advantage for organizations that are willing to invest the effort to pursue it.

By investing in build, test, deployment and environment automation, we substantially reduce the cost of making and delivering incremental changes to software by eliminating many of the fixed costs associated with the release process. If your team is already agile and wants to take their delivery to the next level, I cannot possibly recommend this book highly enough. Aug 04, Rod Hilton rated it it was amazing Shelves: Feb 19, Serge Boucher rated it it was amazing. There are many sentences, paragraphs, and even pages that can be skipped because they are obvious or just a rehash of something earlier or both.

But CI is just the first step. Combining an uncanny vision for emerging technology trends, awareness of available delivery delifery, massive experience in the realm of software delivery, and well articulated delivery strategies, the authors offer a relatively vendor-agnostic discussion of the delivery pipeline that ensures code quality, quick time-to-market, and painless release processes.

Jan 26, Kev rated it really liked it. Maintaining them over time dwlivery harder. The authors introduce state-of-the-art techniques, including automated infrastructure management and data migration, and the use of virtualization.

Everybody in IT should read this book, be he programmer, tester or operations specialist. Thanks for telling us about the problem. It is a handbook for every possible angle about delivering software continuously. He showed me around his project and one of the humblf aspects of his highly disciplined team was the fact that they deployed their software into production every night.

Decided that in fairness to the THD, s/n thread the IG should be I modified this IG a long time ago — looks like it’s in need of modding. This same upgrade can be performed on the IG, SG-. 18, and incorporated into your kit by Heathkit, depending on when your particular model was sold.

It originally seemed likely that the higher ratio was responsible for the low distortion performance of the HP oscillator. For the square wave generator, the CDB was substituted for the equivalent 74C14B, since the other chip was handy.

The PCB files package includes: The PCB files package includes:. Remove the B and quite a few places have the 74C Let us know how it goes. Maybe you know the feeling—so many toys, so little time: I’d probably add plated iv-5218 holes with tiny pads to the top layer as well.

His write up on it is here. I wish they would indicate that on the “obsolete” page. You could suffer a fatal electrical shock! The board is intended for single-sided, DIY fabrication.

The PCB layout, as seen in Eagle is at left.

Any help would be appreciated. Bottom view of the oscillator board wiring. The main concern about the diode is its forward characteristics. Dick also left out C32,46 and R29, though he and Larry think that these last three might be useful. Eagle generates errors if an error check is run on the board. Click on the image at left, for a high resolution pdf file, showing the silk- screen and topside jumper wires.

Looking for other manual?

We would very much like to hear, your results, if you have boards made with the files —ed. Note that this layout is intended for a single sided board.

Click on it for higher resolution. After doing the layout, he fabricated his own, single- sided PCB and successfully built the working generator. Thank you, much appreciated.

Normally, the leads will be positioned on the opposite side from the lamp —ed.

Eagle version-6 is required to open the. Also, Being a project nut, I have several small footprint toroidal transformers on hand. August 27, – The overall dimensions of the board are 5. These free programs can be found on this page: The topside traces shown in the BRD file are only to guide topside jumper installation.

Posted by Shawn S. Any recommendations for a board fabrication place that will do a run of one single sided board for a reasonable price. Adjust the pot for minimum second harmonic distortion.

As such, the topside traces are hethkit guide topside hand wiring and the silkscreen was for guidance, rather than application to the board. I hope that using your new IG gives you as much pleasure as using mine has given me. However, his measurement methods, while indirect, certainly make sense.

Any help would be greatly appreciated. The schematic and the parts list in the construction notes have been updated to show the CDB as equivalent. Other specifications were not tested but the chips have similar speed ratings.

Before doing this project, I had gone through previous iterations of “greening” the critter, beginning way back in the seventies with an article from the Audio Amateur.
