מסתבר שאין לי פה מתכון לקציצות עוף, סוג של קציצות שאני די מחבב, אז הנה משהו שערבבתי לי לאחרונה. הרוטב היא קצת חמוץ וכדי לאזן את זה – גם קצת מתוק, אז תשימו לב. בנוסף הכמויות הן לדי הרבה אוכל – אני מכין בד”כ לשלושה אנשים ואוהב שנשאר לקחת לארוחת צהריים במשרד, אז קחו את זה בחשבון.
This is an open letter to Chris Fisher from Jupiter Broadcasting (and friends) regarding the recent tirade against Google “winning” the court battle against Oracle for the use of the Java APIs.
A short summary for the uninitiated:
After Oracle bought Sun including their Java implementation, they sued Google who implemented (some of) the Java APIs for use in the Android operating system, for copyright infringement in some source code, copyright infringement on the API definitions themselves and a couple of software patents they held about how to implement some Java behavior. Round one: Some source code was ruled infringing, APIs were found non-copyrightable and patents were found not-infringing. Round two: A federal court (that normally rules on patent issues) held the ruling of copying (for Oracle) and patents (for Google) but ruled APIs copyrightable and Google infringing on that. Third round: a jury found that Google’s use of the Java APIs was fair-use and no damages should be awarded.
After the last jury decision, there was a lot of back and forth on the internet, notably one Ars Technica article (“op-ed”), by an Oracle lawyer claimed that the result boils down to nullifying any and all open source licenses:
if you offer your software on an open and free basis, any use is fair use.
Then we come to Chris Fisher – as the host of his Linux Action Show podcast, he has spoke out against Google many times in the past, but this tirade in the discussion of the Oracle vs. Google action in the most recent Linux Action Show #419, really demonstrates well the extents of his Googlephobia (LAS #419, 0:46:42):
One type of task that I often find myself implementing as a bash script, is to periodically generate some data and display or operate on it – maybe through a cron job, watch or simply a loop. Sometimes part of the process is an expensive computation (could be network based, IO intensive or simply subject to throttling by another entity). The way to deal with issues like that in modern programming languages is a caching technique known as “memoization” (based on the word “memorandum”) in the results of an expensive call is retained in memory after the first time, and returned for future calls instead of running the expensive calculation. We also need to clear the cache every once in a while, but that’s another issue.
So, how to implement in bash?
Cloud-init is a Linux technology that allows easy setup and automation of virtual machines. The concept is very simple – the VM infrastructure provides some way of setting some custom data for each virtual machine (many providers call this “user data”), and when the operating system starts the cloud-init service reads that configuration, loads a bunch of modules to handle various parts and let them configure the system. As a user it is very convenient – you write a setup scenario using the variety of tools offered by cloud-init, you can store the scenario in a source control to allow to develop the scenario further, then just launch a bunch of machines with the specified scenario and watch them configure themselves.
The situation is much worse on the MS-Windows side of the fence: want to have an MS-Windows server configured and ready to go? Start a virtual machine, connect to is using RDP and Next, Next, Finish until your fingers are sore. Need to deploy a new version? either retrofit an existing image (again, manually) and risk deployment side effects, or do the whole process again from scratch.
Here’s a script to try to help a bit with the problem – at least on Amazon Web Services: a poor man’s cloud-init-like for MS-Windows server automation.
I’ve been looking a while now for a good way to manage data in MongoDB database servers. The command line tool is OK, but its not really easy to work with, even doing simple stuff like listing the content of a collection.
For a while I’ve been using Genghis, which has an interesting approach to a local graphical interface: it starts a local web server and invokes a web browser to access that server. The UI is pretty nice and very responsive, but it is kind of flaky and lately has stopped working for me entirely. Also the data density you can get from a nice looking web UI is still much lower then you can get in a well designed desktop UI – and when looking at a lot of data records in a database, data density is very important.
Enter Robomongo:
The Heroku toolbelt (which I don’t remember if its mentioned in the “curlpipesh” tumbler mentioned by Amir in his response to my “Fix RVM” post), is a CLI to manage applications on the Heroku PaaS platform. As is common (and horrible) in this day and age they also offer a ‘curl|sh’ type install on their home page.
While the Debian/Ubuntu specific installer is not entirely horrible – it basically adds the Heroku Toolbelt debian repository to the APT source list, updates the package list and installs it, the “standalone” version is as horrible as it can get: download an unsigned binary from the internet, get root permissions and then do something.
For users of Fedora and other distributions, or just Ubuntu users who don’t like installing external repositories on their system, here is a simpler method to get the Heroku Toolbelt running on your system without root permissions and downloading scripts off the internet:
As can be evident across the web (for example in this article), the current discussion fueled by Google’s self driving car news and a the possible development plans of other small and large companies is often concerning itself with the morals of a software driven car1. Which is, frankly, unfortunate.
I think that the only people that should be really bothered by all this talk of “who should the autonomous car kill (in case of an accident)” discussion are the programmers hard at Google and other companies, who are suddenly held to a much higher moral standard than expected of programmers who are responsible, today, to hundreds of lives in each instances – such as programmers for railway systems and passenger jets flight control software.
When you look at the problem from the perspective of autonomous transport control software, that is right now being used to safely transport millions of humans daily, its obvious that the main concern of the designers is to have quantitatively better response (more consistent and faster, in that order) than a human, for adverse situations, but qualitatively better – that is, the systems will not pretend to make decisions morally better than a human would do at any given situation, just perform better on the exact same actions that the human it replaces will have taken anyway.
So when a Google self-driving car programmer comes answer to the “trolley problem” or the “fat man problem” discussed in the linked article, they should not be held to a higher moral standard than the average driver, because that is who they are replacing.

I’m very grateful for the free Wi-Fi on the train, the coffee shop or the municipal free Wi-Fi, but the content filter they have on their proxies is sometimes really weird – for example it may blocks one of my favorite podcasts website (the Jupiter Broadcasting network) under the category “streaming media” even though they don’t actually host their video files, but they do let through YouTube and Facebook (where most cat videos are posted these days). So apparently Israeli Rail has an aversion to streaming media so they won’t let me send an email to a small podcast, but I can watch all the cat videos I want. Weird. Also, most VPN services are blocked by default, so no help will be coming from that way1.
So, to fix that, here’s a small workaround using an external proxy – this is rather simple, but it does assume you have all kinds of tools that most users won’t have just lying around – but if you’re a Linux geek you should do just fine.
אני בד”כ לא כותב על פוליטיקה בבלוג שלי, אבל באמת קשה לי מאוד לשתוק על מה שקורה היום בישראל: ממשלת נתניהו האחרונה (כך לפחות אנחנו מקווים), ממשלה צרה על הקואיליציה הכי קטנה שאפשר לעשות (שהצליחה גם לארגן את כל חברי האופוזיציה להתנגד לה בכל הצבעה) היא הממשלה שגם קמה על הכי חלוקת שלל. כמות הכסף שבנימין נתניהו מחלק מהקופה הציבוריות היא מדהימה! האמת שעדיין לא ברור לי כמה – זה 6.7 מיליארד שקל לפי כתבה אחת ,9 מיליארד שקל לפי כתבה אחרת או 11.5 מיליארד שקל לפי כתבה שלישית, בכל מקרה זה כמויות לא נתפסות של כסף הובטחו על ידי “ראש הממשלה” לתחומים צרים שמהם ירוויחו (במקרה הטוב) קבוצות קטנות באוכלוסיה הישראלית.
למי שלא מבין כמה כסף פה נזרק למתנות לחברי הקואליציה, בואו נשים דברים בפרופורציה – מדובר בכ-3% מכל תקציב המדינה ב-2015! רק על שוחד בחירות! וגם בכלל לא ברור מאיפה יבוא הכסף– בתקציב 2015 כבר יש גרעון של מעל 3 מיליארד שקל.
אבל הלוואי וזו היתה הבעיה העיקרית. הבעיה העיקרית היא ההבטחה של בנימין נתניהו לזרוק את כל הנורמות החברתיות וההגיינה הציבורית לפח תוך שהוא מעודד שחיתות בכספי ציבור, בצורה שלא היתה כמוה מאז התקופות החשוכות ביותר בתולדות ישראל. Read the rest of this entry »
On Wednesday I complained about the latest UN*X fad of installing software by running scripts from the internet, without any regard to how your operating system handles software installation.
Docker, that I complained about last time, at least has a script that takes into account the local software management solution (uses apt for Ubuntu, yum for Fedora, etc), but RVM – the Ruby Version Manager which is a popular tool among rubyists everywhere, just downloads a bunch of executable stuff (granted, most of it are scripts, but the difference is lost on most people) into arbitrary location on your file system. At least it doesn’t install system software, oh wait – it does.
While I can’t help with RVM’s desire to install system level software (that it actually needs because one of the things you want RVM to do for you is to compile ruby versions from source), I can try to help you figure out how to install RVM where you want it and use it how you want it.
