Hadoop Interface Taxonomy: Audience and Stability Classification
Motivation
The interface taxonomy classification provided here is for guidance to developers and users of interfaces. The classification guides a developer to declare the targeted audience or users of an interface and also its stability.
- Benefits to the user of an interface: Knows which interfaces to use or not use and their stability.
- Benefits to the developer: to prevent accidental changes of interfaces and hence accidental impact on users or other components or system. This is particularly useful in large systems with many developers who may not all have a shared state/history of the project.
Interface Classification
Hadoop adopts the following interface classification, this classification was derived from the OpenSolaris taxonomy and, to some extent, from taxonomy used inside Yahoo. Interfaces have two main attributes: Audience and Stability
Audience
Audience denotes the potential consumers of the interface. While many interfaces are internal/private to the implementation, other are public/external interfaces are meant for wider consumption by applications and/or clients. For example, in posix, libc is an external or public interface, while large parts of the kernel are internal or private interfaces. Also, some interfaces are targeted towards other specific subsystems.
Identifying the audience of an interface helps define the impact of breaking it. For instance, it might be okay to break the compatibility of an interface whose audience is a small number of specific subsystems. On the other hand, it is probably not okay to break a protocol interfaces that millions of Internet users depend on.
Hadoop uses the following kinds of audience in order of increasing/wider visibility:
- Private:
- The interface is for internal use within the project (such as HDFS or MapReduce) and should not be used by applications or by other projects. It is subject to change at anytime without notice. Most interfaces of a project are Private (also referred to as project-private).
- Limited-Private:
- The interface is used by a specified set of projects or systems (typically closely related projects). Other projects or systems should not use the interface. Changes to the interface will be communicated/ negotiated with the specified projects. For example, in the Hadoop project, some interfaces are LimitedPrivate{HDFS, MapReduce} in that they are private to the HDFS and MapReduce projects.
- Public
- The interface is for general use by any application.
Hadoop doesn’t have a Company-Private classification, which is meant for APIs which are intended to be used by other projects within the company, since it doesn’t apply to opensource projects. Also, certain APIs are annotated as @VisibleForTesting (from com.google.common .annotations.VisibleForTesting) - these are meant to be used strictly for unit tests and should be treated as “Private” APIs.
Stability
Stability denotes how stable an interface is, as in when incompatible changes to the interface are allowed. Hadoop APIs have the following levels of stability.
- Stable
- Can evolve while retaining compatibility for minor release boundaries; in other words, incompatible changes to APIs marked Stable are allowed only at major releases (i.e. at m.0).
- Evolving
- Evolving, but incompatible changes are allowed at minor release (i.e. m .x)
- Unstable
- Incompatible changes to Unstable APIs are allowed any time. This usually makes sense for only private interfaces.
- However one may call this out for a supposedly public interface to highlight that it should not be used as an interface; for public interfaces, labeling it as Not-an-interface is probably more appropriate than “Unstable”.
- Examples of publicly visible interfaces that are unstable (i.e. not-an-interface): GUI, CLIs whose output format will change
- Deprecated
- APIs that could potentially removed in the future and should not be used.
How are the Classifications Recorded?
How will the classification be recorded for Hadoop APIs?
- Each interface or class will have the audience and stability recorded using annotations in org.apache.hadoop.classification package.
- The javadoc generated by the maven target javadoc:javadoc lists only the public API.
- One can derive the audience of java classes and java interfaces by the audience of the package in which they are contained. Hence it is useful to declare the audience of each java package as public or private (along with the private audience variations).
FAQ
- Why aren’t the java scopes (private, package private and public) good enough?
- Java’s scoping is not very complete. One is often forced to make a class public in order for other internal components to use it. It does not have friends or sub-package-private like C++.
- But I can easily access a private implementation interface if it is Java public. Where is the protection and control?
- The purpose of this is not providing absolute access control. Its purpose is to communicate to users and developers. One can access private implementation functions in libc; however if they change the internal implementation details, your application will break and you will have little sympathy from the folks who are supplying libc. If you use a non-public interface you understand the risks.
- Why bother declaring the stability of a private interface? Aren’t private interfaces always unstable?
- Private interfaces are not always unstable. In the cases where they are stable they capture internal properties of the system and can communicate these properties to its internal users and to developers of the interface.
- e.g. In HDFS, NN-DN protocol is private but stable and can help implement rolling upgrades. It communicates that this interface should not be changed in incompatible ways even though it is private.
- e.g. In HDFS, FSImage stability can help provide more flexible roll backs.
- What is the harm in applications using a private interface that is stable? How is it different than a public stable interface?
- While a private interface marked as stable is targeted to change only at major releases, it may break at other times if the providers of that interface are willing to changes the internal users of that interface. Further, a public stable interface is less likely to break even at major releases (even though it is allowed to break compatibility) because the impact of the change is larger. If you use a private interface (regardless of its stability) you run the risk of incompatibility.
- Why bother with Limited-private? Isn’t it giving special treatment to some projects? That is not fair.
- First, most interfaces should be public or private; actually let us state it even stronger: make it private unless you really want to expose it to public for general use.
- Limited-private is for interfaces that are not intended for general use. They are exposed to related projects that need special hooks. Such a classification has a cost to both the supplier and consumer of the limited interface. Both will have to work together if ever there is a need to break the interface in the future; for example the supplier and the consumers will have to work together to get coordinated releases of their respective projects. This should not be taken lightly – if you can get away with private then do so; if the interface is really for general use for all applications then do so. But remember that making an interface public has huge responsibility. Sometimes Limited-private is just right.
- A good example of a limited-private interface is BlockLocations, This is fairly low-level interface that we are willing to expose to MR and perhaps HBase. We are likely to change it down the road and at that time we will have get a coordinated effort with the MR team to release matching releases. While MR and HDFS are always released in sync today, they may change down the road.
- If you have a limited-private interface with many projects listed then you are fooling yourself. It is practically public.
- It might be worth declaring a special audience classification called Hadoop-Private for the Hadoop family.
- Lets treat all private interfaces as Hadoop-private. What is the harm in projects in the Hadoop family have access to private classes?
- Do we want MR accessing class files that are implementation details inside HDFS. There used to be many such layer violations in the code that we have been cleaning up over the last few years. We don’t want such layer violations to creep back in by no separating between the major components like HDFS and MR.
- Aren’t all public interfaces stable?
- One may mark a public interface as evolving in its early days. Here one is promising to make an effort to make compatible changes but may need to break it at minor releases.
- One example of a public interface that is unstable is where one is providing an implementation of a standards-body based interface that is still under development. For example, many companies, in an attampt to be first to market, have provided implementations of a new NFS protocol even when the protocol was not fully completed by IETF. The implementor cannot evolve the interface in a fashion that causes least distruption because the stability is controlled by the standards body. Hence it is appropriate to label the interface as unstable.

INSIDE THE MAFIA (director: Edward L. Cahn; screenwriter: Orville H. Hampton; cinematographer: Maury Gertsman; editor: Grant Whytock; cast: Cameron Mitchell (Tony Ledo), Grant Richards (Johnny Lucero), Ted DeCorsia (Augie Martello), Louis Jean Heydt (Rod Balcom), Carl Milletaire (Dave Alto), Stephen Roberts (Raycheck), Elaine Edwards (Anne Balcom), Robert Strauss (Sam Galey), Edward Platt (Dan Regent), Frank Gerstle (Julie), Carol Nugent (Sandy Balcom), Richard Karlin (Chins), Jim L. Brown (Doug), Michael Monroe (Buzz); Runtime: 72; 1959)
Reviewed by Dennis Schwartz
A flat fictionalized version of the infamous Appalachian Mafia meeting in the 1950s of all the top crime bosses. In this version, shot in B/W, semi-documentary style, the meeting takes place in crime boss Dan Regent's (Platt) house in upstate N.Y., in a place called Apple Lake. Grant Richards plays a Lucky Luciano Mafia kingpin-type called Johnny Lucero, returning illegally to the US after ten years deportation. He plans to be here for a few hours on the day of the September 18th mob meeting, sneaking into the country by landing his private plane in a small upstate airport. Lucero arranges for the gangland meeting to reorganize the Mafia after the attempt on his life was uncovered and the mob's business isn't growing at a rapid enough pace for him.
Augie Martello (DeCorsia), eastern boss of the Mafia, arranged for the hit on Lucero, but was thwarted when someone ratted him out. One of Regent's henchmen, Julie (Gerstle), took the job of rubbing Augie out, but only wounded him. With Augie still clinging to life in an undisclosed nursing home, he is visited by his loyal and ruthless underling, Tony Ledo (Cameron Mitchell). Tony gets his permission to try and rub Lucero out again, this time at the upstate airfield where he will land for the meeting. By overturning Lucero's leadership, Augie plans to become the Mafia big boss. But this hit of Lucero can only be successful if Augie remains alive, since Tony is too low on the Mafia totem pole to be accepted for leadership by the other crime bosses.
  But complications come about when a state trooper (Brown) visits Anne and a car mechanic (Monroe) who is dating Sandy, comes over to pick her up. They also become hostages. One other plane lands, it is Dave Alto (Carl), someone who didn't show up to the meeting Tony arranged to go over his plan to get Lucero with the other rebels in the organization. Tony is suspicious why he comes to this meeting and not his, being that his wife told Tony she couldn't get hold of him because he was out fishing. The hostages get a chance to see how ruthless the Mafia boys are, as they witness the killing of Dave Alto and his pilot.
A news bulletin flash states Augie just died, which causes the worried Tony to change his plans. He will now bargain with Lucero, telling the boss he will spare him, but only if he can get the other crime bosses to give him Augie's place in the organization.
The climax comes when Tony and Lucero attend the meeting, but Lucero outfoxes him and figures out who the other conspirators were with Augie, and guns them all down before the state police arrive and arrests the one's still alive.
Nothing new is uncovered about the Mafia. It all seems like an exploitive exercise to cash in on the public's curiosity about the Mafia, especially with all the newspaper reports about its real meeting taking place in 1959. There is some nasty action, lots of bad guy Mafia men talking tough to good small town people kind of stuff, but the film was too dry to be anything but mediocre.

I've never been a person to have a fixed mindset when it come to the future. My big interest for a long time has been behind the scenes television production, particularly in live environments (news, sports), mostly because I fell into it after gaining my Bachelor of Theatre. However, being given the opportunity to work with various software and be involved in the output of subtitles (or captions), has led me on a web development journey.
he COVID-19 crisis resulted in the closure of almost all active sets, including mine, giving me an opportunity to re-evaluate my career path. I do not have specifics about my future, what I do know is I'm pretty sure coding is awesome, and I have requirements for the environments I work in.
Sometimes in social settings, my anxiety can get the better of me and affect how I listen or hear people. It feels like audio dyslexia for lack of a better term. Depending on the degree of stress I feel, my ability to communicate how I am feeling or calm myself down from that can vary. I have found the mindfulness practices we have been encouraged to explore during our study to be very helpful in giving me a stronger sense of calm throughout my day. I will continue to practice this so I have a better foundation to work with.
For the past few years, I have been mostly working from home or with very few people around me, so I think it will be quite an adjustment, going into a campus full-time. I am a bit apprehensive but mostly looking forward to it. I'm aiming to push myself more socially in this experience and initiate conversations with others more often.
My strengths are that when real crisis happens, I am very calm and ordered. Despite being a fairly anxious person, there is something to say for what constantly prepping for disaster does to your brain. When it actually occurs, I often feel very clear-headed and great at delegating out tasks to resolve issues quickly. I am also a very creative person, and that will never change. Although I love a good spreadsheet, sitting around and drawing for 12 hours also sounds delightful. I hope to ultimately end up working with people that fosters this aspect of me, too.
A limitation of mine is that when people around me get hot-headed or raise their voice, and their body language changes, I can feel under threat even if I am not involved at all. I am slowly conquering this reaction, but it can be quite involuntary and uncomfortable. My fight or flight kicks in. As a result, I can tend to avoid conflict. I would like to gain skills at EDA to manage this better.
I have been able to set myself up, with the support of friend and family, so that I can focus on only EDA during this period. This means I will commit myself to showing up every day and being engaged with the material and people throughout the course. I know there will be hard days, we will all have them, but I will communicate with staff if I find I am struggling in any way that feels beyond being able to deal with it myself. I am also commiting to look after my mental and physical health during this period, as it is just as important if I am going to be taking in so much new information. I'm looking forward to the yoga classes for a start.
I expect the facilitators to be available during office hours for assistance with struggles I may have with the tech or cultural components, and also any social issues that may arise. So far, everyone has been great at responding to me in a timely fashion, and if they aren't available they have let me known when they next are. I also hope to be able to discuss personal issues with the facilitators should anything in my home life impact my studies. Again, all indications so far have been that this will be the case.
Lastly, if I am not meeting the mark in any component and it is clear that I am not aware that I have not understood something, I would hope a facilitator would point this out to me and send me in the right direction of resources to get me back on track.

About


Yacht skippers must hire a local ship's agent to handle their port clearance. The agent will also be needed to arrange for a haul out, repairs or diesel fuel. One agent, who has proved to be good, is Operistmo. Call then on VHF channel 16 or 67 to make arrangements to enter the harbour "for emergency purposes" to avoid any delays.
The offices of Operistmo are located two blocks NW of the inner harbour.
This is the only port south of Acapulco where a yacht can haul out, and the only one where larger yachts can safely wait for a Tehuantepec gale to pass.
It is less dirty than Lazaro Cardenas and has less shipping traffic.
Yachts entering the outer harbour must proceed directly through the narrow gap in the quay into the inner harbour. Then, turn hard to starboard and berth alongside the high seawall on the SE side. The Navy also use this seawall.
The Port Captain's office is straight ahead in the SE corner of the inner basin.

TIncludeType = procedure (Sender: TObject; const Command: string;
Params: TStrings; var IString: string) of Object;
The TIncludeType type is the type for OnInclude events. These events occur when server side include syntax is encountered in the HTML document at load time.
The server side include syntax takes the form:
<!--#command arg1="value1" arg2="value2" ... -->
The '#' distinguishes this syntax from an ordinary comment. The command word appears as the Command parameter in the event call. The command word may be followed by zero or more arg,value pairs. These are formed into a TStringList object to make up the Params parameter. For use in THtmlViewer, TFrameViewer, TFrameBrowzer, the parameters can be anything that's convenient.
The HTML text to be inserted is passed back in IString. This string replaces the entire original include statement.
Note that:
Quotes are stripped from the Value parts of Params.
The event handler should contain a Params.Free; statement.
Since version 11.1 freeing Params is done by THtmlViewer, TFrameViewer, resp. TFrameBrowser and you MUST NOT do it.

H2O is the first app to run in the convergence stack, building on top of multiple software frameworks that underpin the Convergence Ecosystem. It is a demonstration of machine learning in Web3, allowing users to run a clustering algorithm on data stored in OrbitDB and publish the resulting AI datasets to the Ocean Protocol blockchain.
H2O makes use of various technologies, including Python, Node and Angular. The app runs the Ocean Protocol Trilobite release code and the latest version of OrbitDB.
H2O is able to generate useful preprocessed datasets for AI and use them to seed Ocean Protocol’s global data market, all on a decentralised storage solution made possible by Haja Networks. Though it is largely demonstrative for now, H2O is the first step toward apps in the convergence ecosystem.

Dota 2 is a free-to-play multiplayer online battle arena (MOBA) video game developed and published by Valve Corporation.
Development of Dota 2 began in 2009 when IceFrog, the pseudonymous lead designer of the original Defense of the Ancients mod, was hired by Valve to create a modernized sequel. Dota 2 was officially released on Steam for Microsoft Windows, OS X, and Linux-based personal computers in July 2013, following a Windows-only public beta phase that began two years prior.
Dota 2 has a widespread and active competitive scene, with teams from across the world playing professionally in various leagues and tournaments. Premium Dota 2 tournaments often have prize pools totaling millions of U.S. dollars, the highest of any eSport. The largest of them is known as The International, which is produced annually by Valve and held at the KeyArena in Seattle.

Create account and repository on github.com
Go to github.com
and create an account. Once, account is created, create a repository in Repositories
tab and click on the green button New
. The following page opens.
NOTE: A repository is something like a project folder.
Copy repository URL
After a new repository is created, copy the clone url
link. This link is used to clone the repository from server to the computer.
Set working directory
On Mac computers, open Terminal (on windows open Command Prompt aka cmd). I am not an expert on Terminal and it is almost like a black box to me at this point. But for purpose of using git, it is not difficult and we need to know only a few commands.
NOTE: To find Terminal on Mac, search spotlight OR go to
Applications > Utilities > Terminal
. To find Command Prompt on Windows, you can either find it in Accessories Folder in Start Menu, or find it inC:\Windows\System32\cmd.exe
The following are important commands for working with directory:
- Check working directory:
pwd
(orcd ,
for windows) - Use
cd
to change working directory.-
- Go into a folder:
cd ~/documents/github
- Go up one folder:
- Check content of workding directory:
ls
(ordir
for windows) - Make a new folder:
mkdir [foldername]
For our project, we go to our desired directory and create a new folder if necessary.
So, first thing in the terminal
, we check the working directory
pwd
Then, we change the working directory to where we want. I have already alread a folder called GitHub in Documents, so I set the working directory there. You can either create a similar folder, or set an existing folder as your working directory.
cd ~/documents/github
We check the content of our working directory.
ls
Here is a screen shot of the process. As you can see, there are already three folders in the working directory.
Clone the repository to computer
In the terminal
, clone the repository in the working directory (i.e. from step 3: ~/Documents/GitHub/
). To do that, we use git clone
with the url in the terminal command line.
git clone https://github.com/Masood87/Learn-how-to-github.git
NOTE:
git clone
is the first of five git commands we learn here.git clone
essentially clones the repository into your working directory (in our case it is~/Documents/GitHub/
).
Type ls
in the terminal
after git clone
to see the cloned files.
ls
Next, change your working directory to the cloned folder Learn-how-to-github
cd Learn-how-to-github
You can check again the content of Learn-how-to-github
ls
Here is a screen shot of the process. As you can see, Learn-how-to-github
is added and there is nothing inside it yet.
Make a change to repository and git add
After repository is cloned, we either add new files or modify an existing file. In this case, we add add a new folder with four files. In the finder, I add a folder called screenshots
with four .png
files in them.
In the terminal, we check the status of the cloned folder using git status
.
NOTE:
git status
is used to check any changes including modification of codes inside a file (if any).
git status
The changes will be noted in red font. We either accept to update the changes in the repository or ignore it. To accept and upload the changes, there are three steps:
git add
to ….git commit
to ….- and
git push
to ….
To git add
, there are three ways in this case. The first one add screenshots/ only, and the other two add all.
git add screenshots/
git add -A
git add .
Check the status again
git status
Here is a screen shot of the process. After git add
, the status shows four files in green font. These files are changes to be committed.
Commit changes in repository with git commit
The next step after git add
that adds the changes is to lock the changes. This locking does not mean applying the changes, which is done using git push
.
 To sync, type git push
git push
Here is a screen shot of the process. After git add
, there is git commit
and finally git push
. Now the files are synchronized with github.com
Workflow
So far, all we discussed was to set up a new repository / project, and commit changes. Other times, we have to pull
changes others make in the project.
The first thing one does when starting the day to work on a collaborative project is to change directory to the github repository/project using cd
and request a pull
of all the changes.
cd ~/documents/github/learn-how-to-github
git pull
More details coming up…
Others
To see all commands we can use and what they do, just type git
.

To add to snapshot parameters:
- miniumum amount that can be paid to an address. why max? as you can just do multiple releases and bypass it.
- diffrent pay out that pays static amount to top N address.
- change 5000 address limitation to dust threshold parameter?
- extra RPC to merge all payments utxos to a single utxo, wihtout letting someone constantly DOS spend it. some threshold of utxos allows this to happen?
- second "top" param so a range of address can be paid, rather than just the top.
-could be used to pay more than 3999 address, but no way to stop someone paying bottom address over and over wihtout some extra protections, of some kind, unsolved problem.
- work out the maximum number exclude scriptpubkeys. (maybe just check op_return size on plan create? )

klarna
Businessmodel of Klarna
Customer Segments
Klarna has a multi-sided business model, with two interdependent customer segments that are both needed in order to operate:
- Consumers – Individuals who want the flexibility and security that comes with paying for purchases after delivery.
- Merchants – Businesses seeking customers who may want more flexibility in their payments. ### Value Proposition
Klarna offers four primary value propositions: convenience, performance, risk reduction, and brand/status.
The company offers convenience to consumers through Klarna Checkout. The feature enables users to make online purchases with one click, saving them time. This is because all of their payment information is saved the first time they log in. The feature also saves merchants money and time in administration.
The company has demonstrated strong performance by generating strong results for vendors. Positive outcomes for specific merchants include the following:
- Wish.com – 20% increase in average order value, 25% conversion increase, a 40% increase in sales, and an 8.6/10 customer satisfaction rating
- Adlibris – 80% mobile conversion increase and an 8.8/10 customer satisfaction rating
- Fitnessguru – 12% increase in average order value, 25% conversion increase on desktop, and a 40% conversion increase on mobile devices The company reduces risk through various protection features. It offers Pay After Delivery, which enables consumers to pay only after their purchase has been received. They have up to 14 days after delivery to make the payment. Klarna also offers a Purchase Protection program in case of problems with the order. Specifically, it provides a refund if the item does not arrive; if it is damaged, defective, or incomplete; or if it does not match the seller’s online description. At the same time, Klarna reduces risk for merchants. It pays them immediately after an order has been placed, getting reimbursed for the upfront cost when the consumer pays for the purchase later.
The company has developed a powerful brand because of its success. It is used by 65,000 online retailers and 45 million consumers. It operates in 18 countries and has a 10% share of the eCommerce market in Northern Europe. It oversees 400,000 transactions per day and has presided over more than 315 million transactions since its inception. Lastly, it has numerous prominent clients, including Samsung, Disney, Spotify, Overstock.com, Shoes.com, and ASOS.
Channels
Klarna’s main channel is its direct sales team, through which it acquires most customers. The company promotes its offering through its website and social media pages.
Customer Relationships
Klarna’s customer relationship is primarily of a self-service, automated nature. Customers utilize the website while having limited interaction with employees. The company’s website provides detailed answers to frequently asked questions. That said, there is a personal assistance component in the form of phone and e-mail support.
Key Activities
Klarna’s business model entails maintaining a common platform between two parties: consumers and merchants.
Key Partners
Klarna partners with companies that want to integrate its services into their solutions. It offers preconfigured plug-ins and modules for all common online retail platforms. It also provides a portal for developers to obtain helpful resources. The company’s partners include IBM, pdsCommerce, Pay-On, Cardinal Commerce, and Magento.
Key Resources
Klarna’s main resource is its proprietary software platform, which connects more than 65,000 retailers with over 45 million consumers. It also depends heavily on its technology employees to maintain and enhance the platform. Other important human resources include sales/marketing and customer service employees. Its staff includes individuals from many prominent firms, including Google, Apple, Facebook, PayPal, Experian, and Zynga. Lastly, as a relatively new startup it has relied heavily on funding from outside parties, raising $291.3 million from 12 investors as of March 2014.
Cost Structure
Klarna has a cost-driven structure, aiming to minimize expenses through significant automation and low-price value propositions. Its biggest cost driver is transaction expenses, a fixed cost. Other major drivers are in the areas of sales/marketing and customer support/operations.
Revenue Streams
Klarna has four revenues streams:
One-Time Fees – These consist of the following:
- Merchants – Klarna charges a set-up fee for certain features such as Klarna Checkout.
-

An id attribute is used to point towards an HTML element like h1, when you give an id attribute to an element it is unique to that speicfic element meaning that you can only use it once, whenever you give your chosen element the id attribute it will look for styles you have selected from your CSS file and will be applyed across every HTML document that is linked to your main CSS file.
As per the picture below you can see the two different attributes both have different id tags.
Now the next picture is from a CSS file showing you some of the different styles that can be applied
As you can see from the picture examples the headings and subheadings both have different styling effects that are going to change their look.
Now the class attribute is like the id attribute but unlike the id your able to use multiple classes on one element the benefit of this is that you can have many classes that all have different style effects.
As per the pictures below you can see there are two different types of classes
Now if we were to add both of these classes with an attribute the styling effects will take effect. The next photo is an example with both classes.
So as you can see there are many different ways that your able to style your webpage and make it look unique.

Apple stops signing iOS 13.1.2 and iOS 13.1.3, blocking downgrades
by Chance MillerApple has stopped signing iOS 13.1.2 and iOS 13.1.3 today. This comes after last week’s release of iOS 13.2, which included additional bug fixes, performance improvements, and new features.
Apple generally stops signing older releases of iOS within a few weeks of releasing an update to the public. iOS 13.2 was released last week, while iOS 13.1.3 was released two weeks before that.
When Apple stops signing an iOS build, it means users are no longer able to downgrade to that version via iTunes. Reverting to older iOS builds is common for those in the jailbreak community and can sometimes also be useful for users who experience significant bugs after updating to the latest version of iOS.
Furthermore, an exploit called “checkm8” has gained traction, offering a jailbreak for older-model iPhones, including the iPhone X.
Yesterday, Apple released the first developer beta of iOS 13.3. This will likely be the next public release of iOS, with fixes for RAM management, Screen Time communication limits, and more.
Apple’s recent iOS updates:
- iOS 13 is now available, these are the 13 best features
- Apple releases iOS 13.1 with new AirDrop features for iPhone 11 and more
- Apple releases iPadOS 13.1 featuring Dark Mode, new Home Screen and multitasking, Arcade, and more
- Apple releases iOS 13.1.1 with fixes for battery drain, Siri, iPhone restores
- Apple releases iOS 13.1.2 with bug fixes for Camera app, iCloud backups, and more
- iOS 13.1.3 is the latest software update from Apple to fix iPhone and iPad bugs [U]
- iOS 13.2 now available with Deep Fusion, new emoji, Siri privacy settings, more

Border agents seize 154 pounds of bologna at Texas crossing
by Associated PressEL PASO, Texas (AP) — No baloney: U.S. border agents seized more than 150 pounds of bologna from a driver entering the country from Mexico.
The U.S. Customs and Border Protection says in a news release that the driver told agents Thursday at the El Paso crossing that he had rolls of frozen turkey ham in his pickup truck. Upon further inspection, though, the agents determined that it was 154 pounds of Mexican bologna, which is made of pork.
The agency says the driver was released but the bologna was seized and destroyed. It says bologna can’t be carried across the border because it could introduce foreign animal diseases to the domestic pork industry.

Preface
This book is not a typical O'Reilly book, written as
a cohesive manuscript by one or two authors. Instead, it is a new
kind of booka bold attempt at applying some principles of open
source development to book authoring. Over 300 members of the Python
community contributed materials to this book. In this Preface, we,
the editors, want to give you, the reader, some background regarding
how this book came about and the processes and people involved, and
some thoughts about the implications of this new form.

"In this country you have to change quickly, and all the time; otherwise people say, 'You already did that...Next!'. I want to reply 'Wait, wait...it seems like the same film, but it's not..."
-Martin Scorcese
The subject of the much anticipated, new Scorcese film, Kundun, is not clear. This is not a liability. The most that can be said is that it is a cinematic description of events surrounding the life of the 14th Dalai Lama. Unlike, previous films by the director (Taxi Driver, Alice Doesn't Live Here Anymore), however, anything beyond this description is mere speculation. I was not sure what to make of Scorcese's last film Casino (something more than Goodfellas but less than Raging Bull). Kundun, unlike Casino, whos formal merits are undeniable but that somehow never leaves the realm of conventional cinema, transcends previous elements of Scorcese's style by using devices familiar to the director in wholly new ways. The voiceover is only the most obvious example which in this film is an accomplished and integrated layer of the film as opposed to a crutch or support to an overburdened narrative as it has been elsewhere in Scorcese's films. The director has offered an unlikely film, to say the least, and one that is a happy indication that he is not through astonishing us.
The film has been faulted in various sources for its lack of dramatic cohesion. That Kundun does not benefit from the deft plotting and eerie characterization of a film like Taxi Driver is undeniable, however, to cite this as a fault seems short-sighted. By his own admission, there was little interest in approaching Kundun, along classical lines; the dramaturgy of the film is particularly loose, breaking from the narrative for long periods of time for the Dalai Lama (the title character) to comtemplate and debate key decisions with his advisors or for Scorcese to simply present moody montages. Formally, Scorcese employs a number of motifs including shoes and ancient art (the sand Mandala) layered with a nearly constant use of music. The result is not the type of film we have come to expect but a type of sound-poem instead. A film as concerned about conveying mood, intention and meaning as it is with generating pace.
The careful craftsmanship that has produced Kundun is evidenced by the approach Scorcese took to the film. The very first translations of the concept came not in the way of a conventional storyboard but rather as loose sketches or visual ideas. The precise plot thrusts were left deliberately, vague a the director focussed his preparatory work on how best to convey mood through the visual construction of the film as well as the cinematography. DOP Roger Deakins has credited Scorcese with paying particular attention to how the his lighting would serve as one of the key players in any scene. (There is an excellent account of the circumstances surrounding the photography and production of Kundun in the February issue of Americain Cinematographer). That all this was achieved on a relatively low budget is testimony to the team's technical mastery.
It seems clear that this film is destined for a Western audience: the actors all speak in english (albeit somewhat awkwardly) and although, the cinematic merits in and of themselves are reason enough to see Kundun, there is little, thematically, in the film that an Eastern audience would not already be aquainted with. This being the case Scorcese's strategy seems particularly well chosen. In opposition to the necessary perversions that come with this territory (not using the mother tongue, etc..) the style of the film in terms of the narrative strategy and formal arrangements employed remains true to the culture being portrayed. The serene beauty and meditative tone of Kundun are a more responsible treatment of Eastern themes than, for instance Schindler's List is of Germany during WWII. In other words by confronting the viewer with a film that falls outside the realm of conventional cinema Scorcese compenstaes in some ways for other necessary distortions. The result is both more legitimate and responsible than a film like Schindler's List that attempts to cloak its deceptions in more duplicity; the equivocal, lowest comon denominator, button pushing, that is the Hollywood continuity style.
As usual, the fact that great films such as this receive only a pitiful release here in Ottawa must be opined. In fact if I am not mistaken Kundun's first-run here in the capital lasted 2 weeks and consisted of one screen at the Capitol Square cinema (one of the marginally better venues we have). It is both depressing and surprising that this was the case since it is largely a reflection of popular tastes. It is a shame that even Scorcese's stature was not enough to keep the film around.

Snake Eyes A movie review by "Average Joe" Barlow (c) Copyright 1998
STARRING: Nicholas Cage, Gary Sinise DIRECTOR: Brian De Palma WRITERS: Brian De Palma and David Koepp RATED/YEAR: R/1998
Paul Thomas Anderson's "Boogie Nights" wow-ed the critics last year, and rightfully so: the film's frank portrayl of the pornographic industry/drug culture of the late seventies was highlighted by a great script, virtuoso acting, and some of the most innovative cinematography ever seen in a low-budget film. Virtually every review mentioned its incredible opening shot, in which a "God's-eye-view" camera swoops down from the sky, pans over the exterior of a popular night-club, then drifts inside. We then "walk" through the club, meeting our primary characters as we dodge the dancers and waitresses. This description may not sound terribly impressive, but look closely: the shot was filmed in ONE continuous four-minute take, with no cuts or edits. The effect is subtle, but it effectively draws us into the twisted world of the movie by removing the cinematic devices (including edits) that tend to distance audiences from the action. Director Brian De Palma, probably best-known for his famous film adaptation of Stephen King's "Carrie," does Anderson one better with his new movie "Snake Eyes." In the opening scene, we meet Rick Santoro (Nicholas Cage), a New Jersey police officer in charge of security at a championship boxing match. We follow Cage as he places a bet on the match, fights a criminal, chats with both his wife and his mistress on the telephone, hangs out with his best friend Kevin Dunne (Gary Sinise), notices two suspicious women, watches the fight... and witnesses a murder. That's a lot to absorb in the opening scenes of ANY movie, but get this: De Palma shoots it all in a single unbroken take, lasting nearly twenty minutes! It's a flawless performance from all involved, and the actors never falter as the camera works its magic. No matter what the critics may think of the movie, this scene is going to get attention. The murder victim is an influential politician, heavily involved with a secret government project (is there any other kind?) designed to produce a new type of missile. Santoro knows two things: other people will die if the killer is not apprehended, and if he doesn't get to the bottom of the case before the FBI arrives, his friend Dunne (who was away from his post at the time the shooting occurred, violating the orders that he'd received) may be blamed for the murder. A tropical storm will prevent the arrival of the FBI for ninety minutes, and the two men begin their investigation. The exits to the arena are sealed, and 14,000 people, one of whom is a killer, watch and wait. The film uses a creative technique to get us involved in the mystery: we, the audience, never witness certain important events (such as the boxing match, which contains an important clue) for ourselves. Instead, we must rely on the recollections of the various characters, who disagree with each other as often as not. What really happened? Who's right? This is the mystery that Santoro (and we) must find out. One of the many wonderful touches in this film is the passage of time: one minute of screen-time equals one-minute of real time, so when Santoro announces that they have ninety minutes to solve the crime, you can set your watch by his word. The film's attention to detail does not rest there: one of our characters has very poor eyesight, and when she loses her glasses early in the film, her subsequent scenes are shot out of focus, giving us a window into her confusion. The intelligence of the movie is clearly shown via shots like this; De Palma clearly is a master of drawing an audience into his world, something he demonstrated equally well in "Carrie." Our characters are consistently interesting, their urgency is communicated, and the air of mystery is so high that when one of our characters turns out to be something other then he/she initally appears, we simply accept it. We're too lost in this world to argue. Although we're not privy to everything, De Palma does allow us access to certain information that the onscreen characters don't have. In one scene, Sinise's character stands outside of a door, listening, trying to decipher what he's hearing on the other side. De Palma does not leave us in suspense, though: the camera, initially behind Sinise, rises, hovers over him, then gives us a peek over the wall and into the room beyond. Another effective shot occurs later in the film, in which Cage's character compares notes on the shooting with one of the "suspicious females" he saw at the outset. We get a "split-screen" display, in which Cage's memory of the shooting is displayed in the left half, and the woman's in the right. They run tangent, in perfect synch, with only very slight differences which reflect their own conflicting memories. The scene is brilliantly edited, and offers new insight into the crime. Stylistic touches such as these make it impossible not to get drawn in. Sadly, it all comes undone in the film's final moments. A major plot problem: a murder has been committed, and the staff of the arena knows that the police want to see all the security tapes that were shot during the fight. All of them are viewed, but the information they need is not there. Then, towards the end of the movie, an employee suddenly remembers that he just installed a NEW, SECRET security camera that very morning! Sheesh, how do you forget about something like that? But the film's biggest offense is the final confrontation between Cage and the villain. It's an absolute joke: the outcome is decided not by the chess-like strategy that the story has shown us thusfar, but by dumb luck: imagine if, in the final lightsaber battle between Vader and Luke in "The Empire Strikes Back," a giant asteroid had appeared from nowhere, crashed through Cloud City, and knocked Vader down the exhaust shaft. That's the same ballpark as the plot-twist used to resolve "Snake Eyes." After being riveted by the movie up until this point, it was impossible not to feel a bit cheated. Pardon my crassness, but if this film were a woman, she'd make out with you for two hours, rip off all your clothes, then suddenly announce that she has to leave. Sure, it's fun at the time, but ultimately unsatisfying. Nonetheless, there's much to like about "Snake Eyes." I'll probably see it at least once more, if only for the flawless opening scene and the other stylistic touches that typically mark De Palma's work. I doubt I'll stay for the final fifteen minutes again, though.

Brazil’s president criticizes DiCaprio over Amazon fires
RIO DE JANEIRO — Brazilian President Jair Bolsonaro on Friday said actor Leonardo DiCaprio had funded non-profit groups that he claimed are partly responsible for widespread fires in the Amazon rainforest this year.
Bolsonaro did not offer proof for the claim when speaking to a small group of supporters in Brasilia.
"DiCaprio is a cool guy, isn’t he? Giving money to set the Amazon on fire," he said.
DiCaprio’s environmental organization Earth Alliance has pledged $5 million to help protect the Amazon after a surge in fires destroyed large parts of the rainforest in July and August.
The actor’s press representative did not immediately comment on Bolsonaro’s remarks.
The remarks are part of a wider government campaign against environmental non-profit groups operating in Brazil. Some members of Bolsonaro’s administration argue that civil society groups and environmental laws hinder economic development in the region.
Bolsonaro and Environment Minister Ricardo Salles are promoting development in some protected natural areas, even as intentional fires and deforestation in the Amazon have reached levels not seen in a decade.
The criticism of DiCaprio and environmental activists follows a police raid at the headquarters of two non-profit groups in the Amazonian state of Para earlier this week. Local police also arrested four volunteer firefighters and say they are investigating them for allegedly igniting fires to obtain funding from sympathetic donors.
The volunteer firefighters denied any wrongdoing and a judge ordered their release.
Federal prosecutors say their investigations point to land-grabbers as primary suspects for fires in the area, not nonprofits or firefighters.
Brazil’s president has previously suggested, without evidence, that non-profit groups are setting fires in the Amazon. Bolsonaro has also questioned warnings about climate change.
Cattle ranchers, farmers and others have long used fire to clear land in the Amazon.

19 October 2013 - On 17 October 2013, WHO received reports of a cluster of acute flaccid paralysis (AFP) cases in the Syrian Arab Republic. This cluster of ‘hot’ AFP was detected in early October 2013 in Deir Al Zour province and is currently being investigated. Initial results from the national polio laboratory in Damascus indicate that two of the cases could be positive for polio – final results are awaited from the regional reference laboratory of the Eastern Mediterranean Region of WHO. Wild poliovirus was last reported in Syria in 1999.
The Ministry of Health of the Syrian Arab Republic confirms that it is treating this event as a cluster of ‘hot’ AFP cases, pending final laboratory confirmation, and an urgent response is currently being planned across the country. Syria is considered at high-risk for polio and other vaccine-preventable diseases due to the current situation.
A surveillance alert has been issued for the region to actively search for additional potential cases. Supplementary immunization activities in neighbouring countries are currently being planned.
WHO’s International Travel and Health recommends that all travelers to and from polio-infected areas be fully vaccinated against polio.


Managing OS X Profiles with Puppet
29 Mar 2016There are many ways of managing configuration profiles on OS X - you can use MDM, Munki or any one of the other many great tools. My preferred method however is using Puppet.
By using Puppet, I get access to it’s templating features, and I can let others in my team adjust exposed settings through Hiera.
This post will walk you through the development of a a simple Puppet module and how to test it on an OS X virtual machine.
Prep
Before you do anything, you’re going to need a profile. There are plenty of the things on Github, or you could run Profile Manager in a VM (please don’t use it for anything more than this, it should never be managing your devices directly), or in the future you’ll be able to use Erik Berglund’s ProfileCreator.

We are going to keep our module in git - we’ll use GitHub today, as you can get a free repository and the GUI app is really simple. This is not a git tutorial, so all you will need to do it ‘commit’ your code and sync it to Github. Go ahead and get the application and create a new git repository (File -> New in the app once you’ve logged in). It doesn’t matter what you call the repo, but I like to keep my Puppet modules prefixed with puppet-
so they line up nicely in the Finder.
There is one other thing you will need for today: an OS X VM to test in that has Puppet Agent installed. You can find installers over on the Puppetlabs downloads site (10.11 direct link). You should use the ‘Puppet Collection’ versions in the directories marked 10.9
, 10.10
and 10.11
- these contain Puppet 4, which is the current version of Puppet.
The module
Now we’re ready to start writing our module. Open up the directory you just made for your git repo, and create directories called manifests
and templates
inside.
The first file we’re going to create is our profile template. It will be just the same as any profile you’ve worked with before, but we’re putting in a placeholder where you’d normally put in the path to the image you want to be used for the desktop picture. You should probably replace the reverse domain (com.grahamgilbert
) with com.yourcompany
.
That’s our profile template completely finished. If you’ve seen a profile before, it will be familiar - the only change we’ve made is on line 23 where we have replaced what would normally be a path to your desired image with <%= @path -%>
. This is an erb tag that will be replaced with our path by Puppet.
Now for the manifest. We’re going to make use of Sam Keeley’s fork of mac_profiles_handler to handle the installation of our profile. Our module will allow the path to the image we want set as the desktop picture, so we have that as an option at the top of the class. The rest is just telling mac_profiles_handler
to install our profile.
That’s it for our module - you should open up the Github app and commit your code up to Github, creating a repo when the app asks.
Testing it out
We’re going to use a tool called r10k to deploy our code. It uses git to make sure your code is all in the right place and up to date. Hop over to your VM and open up Terminal.app and bash in:
If you are prompted to install the Xcode command line tools, do so. If you are just told which version of git you have, you’re all done.
Next we need to get r10k installed.
And now we need to make our Puppetfile. The Puppetfile simply tells r10k which modules to install. Replace https://github.com/grahamgilbert/puppet-desktop_picture.git
with the HTTPS URL of your git repository for your newly created module. Your Puppetfile can go anywhere on your test VM (in production, you would use something called a control repo to manage this).
Assuming you saved your Puppetfile on the VM’s desktop:
Now all that’s left is to create your site.pp
with a default node that has your class applied to it. You’ll need to do this as root (sudo nano
for example).
Let’s test it:
You should see your profile being applied to your test VM, and if you try to change the desktop picture, you will be prevented from doing so. But what happens if your users need something different?
You have two choices. You could edit your site.pp
to look something like:
But that’s just messy. We should be using a better tool for this job: Hiera. As root:
One final puppet apply
:
Wrap up
We’ve created a module that will apply a profile to our Macs. We’ve set up a quick test environment, deployed our module and it’s dependencies and passed configuration to our module via Hiera. Remember this setup should only be used for testing, as I said before you should be using a control repo with r10k.
If you’d like to see the simple module I made for this post, you can find it up on Github.
