added by bobh Mon Feb 23 13:25:31 2004 The Application layer (7) (HTTP/SMTP/POP/FTP) communicates the received information (such as files) to the user. Presentation layer (6) e.g. encryption methods, character sets, etc. The Session layer (5) e.g. warehouse managers talking on phone about how many packages they want per day (slow up or speed up). Gateways live here. The Transport layer (4) (TCP/UDP) creates connections to the program on that destination machine. e.g. shipping clerk in the warehouse sending mail to employees in different buildings The Network layer (3) (IP) sends packets as far as the network segment e.g. 203.24.13 (not down to the device number <IP_ADDRESS>) using the Internet. Routers work at this level. e.g. like a bad postal svc, mailman walks down Mill Ridge with the package in his hand asking the residents to see if it's for them b/c all he knows to deliver to is a street address, not a house address The Data Link layer (2) (Ethernet/PPP) sends frames as far as the next hop. Only understands the ethernet ip of the host computer. e.g. doesn't know what a street address is, only what a house address is, only picks up mail from mailman with '7212' on it. The Physical layer (1) sends bits onto the wire at standard voltage, bits per second, etc.Compare OSI with TCP/IP Models:
The OSI reference model describes modular building blocks of various functions that must be provided to have program to program communications between similar or dissimilar hosts. Each functional area describes certain tasks that must be performed by network hardware or software in order for these network communications to take place. Not all methods of network communication extend to all the layers of the full OSI reference model. For example, internetwork communications between programs on differing hosts using reliable TCP/IP communications might use all layers of the OSI model, while local Windows for Workgroups communications within the same network using the NetBEUI protocol might have communications occurring only at the Data Link Layer and Physical Layer levels.
One important thing to understand is that the OSI reference model describes what must transpire for program to program communications to occur between even dissimilar computer systems. Each layer is responsible to provide information and pointers to the next higher layer in the OSI model. The Application Layer (which is the highest layer in the OSI model) makes available network services to actual software application programs.
In describing the various functional areas of the OSI reference
model, I will start from the bottom up. However, when we describe
communications between two computer systems, we describe the
communications beginning at one computer system at the highest layer
that communications occur, going down through to the Physical Layer,
through the transmission media and network, over to the other
computer at the Physical Layer, then up through to the highest layer
of communications on the other computer system. These communications
are usually symmetrical. In the case of this type of communications
occurring through a routed internetwork, the network portion of the
diagram (between the OSI reference layers on each computer system),
may also extend on through the Physical, Datalink, and to the
Network Layer.
In the diagram above, the left stack of the OSI reference model represents computer number one, the middle two stacks indicate the actual routed internetwork, and the rightmost stack indicates computer number two. The arrows indicate the path taken by data sent from a program on computer number one to a program on computer number two, through the routed internetwork.
The lowest layer of the OSI reference model is the Physical Layer. It is the foundation of communications between any computer systems. The Physical Layer specifies the transmission media, transmission devices, network structures, and the actual data signals across the transmission media. The transmission media provides the physical path through which data signals flow. The transmission media consists of either bound media (usually some type of cable) which have a central conductor of data signals surrounded by a physical outer jacket, or unbound media which rely on radio waves, microwaves, and infrared signaling.
In most LAN network communications, the Physical Layer describes some type of cabling system as the transmission media. The Physical Layer also describes the transmission devices that attach to the media, the physical connector specifications, and the electrical or optical signaling characteristics (analog or digital, signal levels, and signal encoding methods). The Physical Layer lastly describes the network topology, and how the Physical Layer transmission media is to be distributed (i.e., in a bus, star, ring, mesh, etc., topology).
The most simple type of communications between computer systems (serial or parallel) occurs at the Physical Layer, where the Physical Layer would consist of the transmission media, transmission devices, a simple point-to-point network structure, and network signaling and interface specifications (such as an RS-232 serial communications).
The second layer in the OSI reference model is the Datalink Layer. This layer describes the functions that must occur for LAN communications within a local network. The Datalink Layer provides the first level of organization of the data bits into a rudimentary structure called a Datalink frame. This frame is organized into fields of information that convey the beginning and ending of the frame, the address of the sender, the address of the receiver, a method to ensure that the frame does not contain errors that may have occurred in the course of being transmitted through the transmission media, and an area to provide some basic administrative function (such as flow control, frame length calculations, and protocol decisions). Datalink Layer flow control manages how much data the destination system can handle.
The Datalink Layer is broken into two logical areas, the Media
Access Control (MAC) sublayer, and the Logical Link Control
(LLC) Sublayer. The MAC sublayer refers to the Media Access
Protocol (how do stations on a network gain access to the media and
permission to transmit their data - contention, token passing,
polling), and the physical addressing of stations on the network.
This would include the Source and Destination address sections of
the Datalink frame. The LLC sublayer includes portions of the
Datalink frame administrative or control fields and CRC fields that
are responsible for the frame synchronization, flow control, and
error checking within the frame.
The physical addressing at the Datalink layer (used for source and destination addressing in a Datalink Layer frame) is called a physical address because this address (also called a MAC-layer address) is hard coded into the network interface in their computer or workstation. This addressing is useful for conveying all the information necessary to direct information to and from stations within a local network. The addressing is usually assigned by the manufacturer of the network interface at the time of manufacture, and the first half of the address contains hex address information that is unique to each manufacturer. The last half of the MAC layer address is unique to that individual NIC card. Networks with duplicate addresses can have problem s in knowing where to properly deliver their data. This is why all manufacturers purchase unique identifiers and blocks of unique addresses for all the network interfaces that they manufacture.
When we refer to Ethernet, or Token Ring, or other LAN Networking systems (ARCNET, LocalTalk, FDDI, etc.), we are referring to the Physical and Datalink layer descriptions of these networks. For example, an Ethernet workstation will construct datalink layer frames that may conform to the IEEE 802.3 specification for Ethernet frames, and which follow that specifications requirements for signaling types, levels, media, physical connectors, etc. The Physical and Datalink Layers also specify the Media Access Control methodology (CSMA/CD), Ethernet topologies, and other rules necessary for ensuring a functional network design. The Network Layer is responsible for the internetworking process that needs to occur to reliably send and receive data between networks. It provides logical addressing at the Network Layer (as this addressing is usually specified in software, and is not hard coded into network interfaces as it is at the Datalink Layer), and provides for network routing, flow control, sequencing, and translation functions. Network Layer flow control monitors network connection. Network layer addressing provides addressing that is specific to the logical addressing assigned to a particular network protocol. For example, the Ethernet workstation described in the previous paragraph may have Ethernet as the Physical and Datalink layer network type, and may run both TCP/IP and Novell IPX/SPX as different network layer protocols. Each network layer protocol will have a different logical addressing scheme to enable communication between networks.
This brings up an interesting issue involving network protocols. Without going too deep into the subject, there are some common protocols used in LAN networking that do not extend to the network layer. These include DEC LAT, NetBIOS, NetBEUI, and others. Because they have no provisions for network layer addressing and routing, connecting these protocols between different LAN's must be done with MAC layer devices such as LAN bridges or LAN switches. Protocols that operate at the network layer (such as TCP/IP, IPX/SPX, DECNET, etc.) utilize routers to interconnect networks. Most routers have the ability to route routeable protocols and to bridge non-routeable traffic.
The Transport Layer provides reliable end-to-end communications by providing service addressing, flow control, datagram segmentation, and end-to-end error checking. The Transport layer is the second of three error checking levels in the OSI model (error checking occurs at the DataLink Layer, Transport, and Session Layer). While the Network Layer is responsible for transporting data from Network A to Network B, the transport layer ensures that packets arrives (or is reassembled) in one piece, and make sure that the data is directed to the appropriate service. While I have explained physical MAC-Layer addressing which occurs at the Datalink Layer, and the logical addressing at the network layer, we will now see that the Transport Layer concerns it self with the next layer of addressing described in the OSI model, which is Service Addressing. Service addressing identifies addresses or ports which point to upper layer network services. The transport level addressing also keeps track of multiple connections or conversations which might occur on a network attached computer system. It does this by tracking a connection identifier (connection ID, port, or socket), or by a transaction identifier (which would track each request, as opposed to tracking a conversation). The Transport Layer is also responsible for breaking larger units of data sent down from higher layers into smaller pieces that can be transported across the network. These pieces would then be reassembled at the Transport Layer of the receiving computer system and passed on to that computers higher layers. This is accomplished by assigning segment numbers to fragments of a common conversation. The Transport Layer accomplishes it's contribution to the flow control process by negotiating window sizes.
The Session Layer is responsible for connection establishment, data transfer, and for connection release. In this way the Session Layer provides mechanisms which establish, maintain, synchronize, and manage communications between computer systems. The Session layer is responsible for the establishment of connection ID numbers, and relies on the transport layer to provide the information which identifies the correct services. The Session Layer is responsible for the coordination of acknowledgement numbering and retransmission procedures. It tracks who initially initiated a conversation. Session layer is responsible for re-establishing a logical communications session between computers should that session be prematurely terminated (due to failure at a lower layer in the communications process). The Session layer would either resume the interrupted dialog, or initiates another new session to the other computer system. The Session Layer also manages planned connection release of a communications session.
The Presentation Layer is responsible for translating data into formats that can be readily understood by each computer system. The Presentation Layer concerns itself with translating differences at the bit level, byte level, or character level, and with file syntax. An example of this might be translating data formats between two different computer systems using the TCP/IP protocol, that have different data conventions. One host might use ASCII code and may have the left-most bit be the highest order bit (or most significant bit) in a byte of data, while the other host system utilizes EBCDIC and for which the left most bit is the lowest order bit (least significant bit). Computers need to agree the method of identifying how many bits equals a whole character and what file syntax is used by each system (file organization, beginning and ending boundaries, naming conventions, read and write access security, and file storage methods). The Presentation Layer also concerns itself with data compression and encryption.
Probably the most misunderstood layer of the OSI model is the Application Layer. Contrary to what many people think, this IS NOT the layer where the software application (such as your spreadsheet or word processing program) resides. It is the layer where network applications that facilitate network connectivity reside (file transfer/FTP, virtual terminal/Telnet, and electronic mail, for example), and where service advertisement and service availability are managed. Service Advertisement is the process of letting systems know which services are available on the network. Once it has been made advertised, it must be made available to the computers local operating system.
Network services include file services, print services, message
services, application services, and database services. Network
services are provided at the Application Layer. The Application
Layer makes network services available to a computers local
operating system. This is accomplished through Operating System call
interception, remote operation, or via collaborative availability.
In OS call interception, the local operating system is completely
unaware of the existence of network services. In remote operation
the local system is aware of the network, but the network server is
unaware of the client. In collaborative systems, both the server and
the client are aware of each other and work together to coordinate
service availability. This method is typically used in peer-to-peer
network operating systems.


Week 2 and 3
Hello Friends! I know it has been a while but it is time for my weekly update (well week 2 and 3 but let’s just call it a weekly update haha)! As they say “it is better late then never” and boy African time has been hitting me hard. However, I am now in the zone to right this week’s blog! Alrighty, so this week’s post will be about the various places that I have been to Japan thus far. There are a lot of really cool and interesting places to visit in Japan; moreover, I want to highlight some, not all, of the really cool places that I have been to. So without further ado let’s get started!
Osaka
Hello Friends! I know it has been a while but it is time for my weekly update (well week 2 and 3 but let’s just call it a weekly update haha)! As they say “it is better late then never” and boy African time has been hitting me hard. However, I am now in the zone to right this week’s blog! Alrighty, so this week’s post will be about the various places that I have been to Japan thus far. There are a lot of really cool and interesting places to visit in Japan; moreover, I want to highlight some, not all, of the really cool places that I have been to. So without further ado let’s get started!
One enjoyable place to go to in Osaka is the Umeda Sky Building. It is one of the tallest buildings in Osaka and it has an incredible view at the top.
Dotonbori
Another great place to visit is Dotonbori. Dotonbori is often viewed as the best place to go in Osaka. The streets are adorned with bright lights and there are neon lights laced on every building. It is such a pretty sight. However, there are a bunch of weird things that were in the area (which will be mentioned in the next post).
Nipponbashi (DenDen Town)
This area is also in Osaka and it is considered a “mini” Akihabara. There are so many gaming arcades, electronic stores, manga stores, figurine toy stores, etc. There are also a lot of weird interesting things here (but I will also mention this in my next post……)
Ritsurin Koen
IMHO Ritsurin Koen is one of the most beautiful places in Japan. Ritsurin Koen, or rather Ritsurin Garden, is located on the Shikoku island. It is a historical garden that is full of Japanese pine trees (Matsu – 松). Here are some pictures of the gorgeous garden.
Islands of Japan
Islands of Japan There are four main islands of Japan. Honshu is the biggest Island where Tokyo, Osaka, Kyoto, and other cities are located. Most of the Japanese population lives on Honshu. The other Islands are Hokkaido, Kyushu, and Shikoku.
Anime Quote of the Week
"The sooner they know the frustration of defeat, the greater their growth will be." – Korosensei
I have grown a lot during my time in Japan. This growth was definitely attributed to all of the failures that I have garnered. You only truly learn from making mistakes. Don't be afraid of putting yourself out there.  But if you fail that is even better. I have learned so much Japanese, perspectives, and culture that I would have never had access to if I didn't put myself out there. You may be surprised how much you learn from your failures.
Until next time friends. じゃあ、また - Joel Kwaku Owusu Afriyie

Mindfulness is an activity that results in awareness. To be mindfulness is to discovering something that already yours and then developing and refining it through systematic cultivation and practice. Its like a practice strategy. Mindfulness and awareness always complement each other.
The body scan is a component of mindfulness meditation. I have tried to simply lie down and do nothing, lying on my ned, focusing my attention at the top of my head and then move down the body. This trains attention, trains my mind to be able to move from detail attention to a wider awareness from one moment to the next.
Emotions are simply what we feel, not who we are, if our emotions are who we are, then there is very little we can do about it. “Possessing this insight, one creates the possibility of change within oneself.” Excerpt From: Tan, Chade-Meng. “Search Inside Yourself: The Unexpected Path to Achieving Success, Happiness (and World Peace).” iBooks.

What is a hackathon?
A hackathon is an overnight coding event in which teams spend the weekend “hacking” together to create an awesome project like a game, website, or app! Hackathons are a great way to learn more about coding, meet new people, and build something cool. Check out Dave Fontenot's post on What is a Hackathon? to learn more!
Who can attend?
Any high school student can attend hackBCA IV who lives within a one hour drive from The Bergen County Academies in Hackensack, NJ. If you live outside the one hour radius, a chaperone or family member must be in the area of the event. Questions<EMAIL_ADDRESS>What should I bring?
You should bring your laptop or desktop, school ID, phone, charging cables, and any hardware you plan on using. Power strips, personal hygiene products, and an extra set of clothes are also recommended. Mainly, bring your awesome self!
What if I don't know how to code?
Then you’ve come to the right place! hackBCA is open to students of all levels and beginners are encouraged to come. Hackathons provide an awesome opportunity to dive into programming. At hackBCA, workshops and mentors will help you get started with the basics of programming and you’ll leave our hackathon having learned a lot.
How do teams work?
You can work on a project individually or with a team. You can come as a team, or form a team at the event. Please keep in mind that if planning on submitting for judging. neither teams or individuals can begin working on hacks until after the kickoff ceremony.
How much does this event cost?
hackBCA is absolutely free of cost (including food). Unfortunately, we will not be able to provide travel reimbursement for this year. And as always, during the event be on the lookout for stickers and swag!

Recipe 2.1. Reading from a FileCredit: Luther Blissett ProblemYou want to read text or data from a file. SolutionHere's the most convenient way to read all of the file's contents at once into one long string: all_the_text = open('thefile.txt').read( ) # all text from a text file all_the_data = open('abinfile', 'rb').read( ) # all data from a binary file However, it is safer to bind the file object to a name, so that you can call close on it as soon as you're done, to avoid ending up with open files hanging around. For example, for a text file: file_object = open('thefile.txt') try: all_the_text = file_object.read( ) finally: file_object.close( ) You don't necessarily have to use the TRy/finally statement here, but it's a good idea to use it, because it ensures the file gets closed even when an error occurs during reading. The simplest, fastest, and most Pythonic way to read a text file's contents at once as a list of strings, one per line, is: list_of_all_the_lines = file_object.readlines( ) This leaves a '\n' at the end of each line; if you don't want that, you have alternatives, such as: list_of_all_the_lines = file_object.read( ).splitlines( ) list_of_all_the_lines = file_object.read( ).split('\n') list_of_all_the_lines = [L.rstrip('\n') for L in file_object] The simplest and fastest way to process a text file one line at a time is simply to loop on the file object with a for statement: for line in file_object: process line This approach also leaves a '\n' at the end of each line; you may remove it by starting the for loop's body with: line = line.rstrip('\n') or even, when you're OK with getting rid of trailing whitespace from each line (not just a trailing '\n'), the generally handier: line = line.rstrip( ) DiscussionUnless the file you're reading is truly huge, slurping it all into memory in one gulp is often fastest and most convenient for any further processing. The built-in function open creates a Python file object (alternatively, you can equivalently call the built-in type file). You call the read method on that object to get all of the contents (whether text or binary) as a single long string. If the contents are text, you may choose to immediately split that string into a list of lines with the split method or the specialized splitlines method. Since splitting into lines is frequently needed, you may also call readlines directly on the file object for faster, more convenient operation. You can also loop directly on the file object, or pass it to callables that require an iterable, such as list or maxwhen thus treated as an iterable, a file object open for reading has the file's text lines as the iteration items (therefore, this should be done for text files only). This kind of line-by-line iteration is cheap in terms of memory consumption and fairly speedy too. On Unix and Unix-like systems, such as Linux, Mac OS X, and other BSD variants, there is no real distinction between text files and binary data files. On Windows and very old Macintosh systems, however, line terminators in text files are encoded, not with the standard '\n' separator, but with '\r\n' and '\r', respectively. Python translates these line-termination characters into '\n' on your behalf. This means that you need to tell Python when you open a binary file, so that it won't perform such translation. To do so, use 'rb' as the second argument to open. This is innocuous even on Unix-like platforms, and it's a good habit to distinguish binary files from text files even there, although it's not mandatory in that case. Such good habits will make your programs more immediately understandable, as well as more compatible with different platforms. If you're unsure about which line-termination convention a certain text file might be using, use 'rU' as the second argument to open, requesting universal endline translation. This lets you freely interchange text files among Windows, Unix (including Mac OS X), and old Macintosh systems, without worries: all kinds of line-ending conventions get mapped to '\n', whatever platform your code is running on. You can call methods such as read directly on the file object produced by the open function, as shown in the first snippet of the solution. When you do so, you no longer have a reference to the file object as soon as the reading operation finishes. In practice, Python notices the lack of a reference at once, and immediately closes the file. However, it is better to bind a name to the result of open, so that you can call close yourself explicitly when you are done with the file. This ensures that the file stays open for as short a time as possible, even on platforms such as Jython, IronPython, and other hypothetical future versions of Python, on which more advanced garbage-collection mechanisms might delay the automatic closing that the current version of C-based Python performs at once. To ensure that a file object is closed even if errors happen during its processing, the most solid and prudent approach is to use the try/finally statement: file_object = open('thefile.txt') try: for line in file_object: process line finally: file_object.close( ) Be careful not to place the call to open inside the try clause of this try/finally statement (a rather common error among beginners). If an error occurs during the opening, there is nothing to close, and besides, nothing gets bound to name file_object, so you definitely don't want to call file_object.close()! If you choose to read the file a little at a time, rather than all at once, the idioms are different. Here's one way to read a binary file 100 bytes at a time, until you reach the end of the file: file_object = open('abinfile', 'rb') try: while True: chunk = file_object.read(100) if not chunk: break do_something_with(chunk) finally: file_object.close( ) Passing an argument N to the read method ensures that read will read only the next N bytes (or fewer, if the file is closer to the end). read returns the empty string when it reaches the end of the file. Complicated loops are best encapsulated as reusable generators. In this case, we can encapsulate the logic only partially, because a generator's yield keyword is not allowed in the try clause of a try/finally statement. Giving up on the assurance of file closing afforded by try/finally, we can therefore settle for: def read_file_by_chunks(filename, chunksize=100): file_object = open(filename, 'rb') while True: chunk = file_object.read(chunksize) if not chunk: break yield chunk file_object.close( ) Once this read_file_by_chunks generator is available, your application code to read and process a binary file by fixed-size chunks becomes extremely simple: for chunk in read_file_by_chunks('abinfile'): do_something_with(chunk) Reading a text file one line at a time is a frequent task. Just loop on the file object, as in: for line in open('thefile.txt', 'rU'): do_something_with(line) Here, too, in order to be 100% certain that no uselessly open file object will ever be left just hanging around, you may want to code this snippet in a more rigorously correct and prudent way: file_object = open('thefile.txt', 'rU'): try: for line in file_object: do_something_with(line) finally: file_object.close( ) See AlsoRecipe 2.2; documentation for the open built-in function and file objects in the Library Reference and Python in a Nutshell. |


Mapping the Justinianic Plague: 541-600
The Plague of Justinian or Justinianic Plague (541–549 AD) was the beginning of the first plague pandemic, the first Old World pandemic of plague, the contagious disease caused by the bacterium Yersinia pestis. The disease afflicted the entire Mediterranean Basin, Europe, and the Near East, severely affecting the Sasanian Empire and the Roman Empire and especially its capital, Constantinople.

The site contains a few sections:
-
Section Mapping the Plague includes three maps showing five plague waves from 541 to 600.
The circles are coloured according to a year of an outbreak. Each map is supplied by a relevant spreadsheet with information on an outbreak and my comments.
-
Section Commercial Networks includes a map showing key products of regions and the tight connections between regions. Since the Plague was supposedly spread
by maritime trade, these connections are relevant for understanding the Justinianic Plague.

The scIGPMessage class.
The addresses must comprise the HThread number correctly! A scIGPMessage breaks down as follows. All messages have a header
Register ('R') messages:
The memory read requests do have no extra (empty and obsolete) bytes for the requested contents. Rather, they set the size to 4, and MessageFeatures_t::ReplyLength delivers the reply length information to the memory, and the sent-back message has the corresponding length. This feature make a message CreateReadMessageReply obsolete: if the length is 4, it is a read message.
Neural ('N') messages The messages are sent by scHThread and received by scHThread. More precisely, from AbstractNeurer to AbstractNeurer. The content depends on the message type Type 0 (a spike)
That is, the mimimum length is four 32-bit words. The message is created by the sender scGridPoint, and deleted by the receiver scGridPoint

Six teens arrested after car chase and shootout with cops
by Nicole McCainSix teenagers have been arrested, including one under police guard in hospital, following a car chase with KwaZulu-Natal police that ended in a shootout.
In a statement, the Office of the Provincial Commissioner KwaZulu-Natal said Durban North police became suspicious of a vehicle they spotted on Friday night.
The occupants were six teenagers, aged 15 and 16. When the officers attempted to pull them over, the driver allegedly sped off, leading to the car chase.
At Dumisani Makhaye highway, the teenagers allegedly opened fire on the police officers. One of the teens was injured when the police returned fire.
He was taken to hospital where he remains under police guard.
The five other teenagers were arrested and taken to the Greenwood Park police station. They have been released into the custody of their parents and have been charged with attempted murder and the illegal possession of firearms and ammunition.
Officers also confiscated two firearms, according to the statement.
The teens are expected to appear in the Durban Magistrate's Court on Monday.

“All part of our support system”
We will supply you with your own exclusive area to work in and expand throughout.
Here are some example figures so you can understand the potential this business has;
- Maximum reward for fewer hours...
- Based on 10 machines in 10 venues
- You can expect to work only 10 hours per month
We recommend a maximum of 50p commission per sale to the venue.
- Fresh Start will cost you £1.50 (Boxed in 12’s = £18.00 total)
- You sell @ £4 each
- 50p commission to the venue
This gives you a fantastic profit of £2.00 per sale.
Remember: Venue’s can easily sell dozens in an hour, especially at weekends. Pubs are an excellent venue for this, as you’re focusing on where people drink. They can be out for long periods of time and drink excessive amounts, so may need to purchase a pack ready for the next day!
Here are some conservative figures;
- If each machine sells just 4 packets (8 capsules) per day
- That’s £8.00 profit per machine (after commission has been deducted)
- 10 x machines = £80.00 profit per day
- That’s £560.00 per week!
That’s £29,120.00 per year!
Or £2,400.00 per month for around 10 hours work...
If you base that on an hourly rate, that’s £240.00 per hour!
“We look at it as more of an investment, rather than a job”
From £2,395+VAT
Figures here are based on selling only 4 per day, as above and all commissions have been deducted, so this is your profit!
| Machines | Cost | Potential Monthly Profit | Additional Monthly potential profit (from free machines) |
| 2 machines + 20 packets free | £2,395+VAT | £480.00 | -- |
| 3 machines + 40 packets free | £3,295+VAT | £720.00 | -- |
| 4 machines + 80 packets free | £3,995+VAT | £960.00 | -- |

| 10 machines + Free machine & a massive 500 free packets | £7,995+VAT | £2,400.00 | £240.00 FREE! |
| 20 machines + 4 free machines & a staggering 1,250 free packets | £13,995+VAT | £4,800.00 | £960.00 FREE! |
These are our most popular packages. If you require more machines, or a tailored package, please contact the office for a quote!


Delegation Token Framework: Obtain, Distribute and Use Temporary Credentials Automatically
January 20, 2023 - Gabor Somogyi Marton Balassi (@MartonBalassi)The Apache Flink Community is pleased to announce that the upcoming minor version of Flink (1.17) includes the Delegation Token Framework proposed in FLIP-272. This enables Flink to authenticate to external services at a central location (JobManager) and distribute authentication tokens to the TaskManagers.
Introduction #
Authentication in distributed systems is not an easy task. Previously all worker nodes (TaskManagers) reading from or writing to an external system needed to authenticate on their own. In such a case several things can go wrong, including but not limited to:
- Too many authentication requests (potentially resulting in rejected requests)
- Large number of retries on authentication failures
- Re-occurring propagation/update of temporary credentials in a timely manner
- Dependency issues when external system libraries are having the same dependency with different versions
- Each authentication/temporary credentials are different making standardization challenging
- …
The aim of Delegation Token Framework is to solve the above challenges. The framework is authentication protocol agnostic and pluggable. The primary design concept is that authentication happens only at a single location (JobManager), the obtained temporary credentials propagated automatically to all the task managers where they can be used. The token re-obtain process is also handled in the JobManager.
New authentication providers can be added with small amount of code which is going to be loaded by Flink automatically. At the moment the following external systems are supported:
- Hadoop filesystems
- HBase
- S3
Planned, but not yet implemented/contributed:
- Kafka
- Hive
The design and implementation approach has already been proven in Apache Spark. Gabor is a Spark committer, he championed this feature in the Spark community. The most notable improvement we achieved compared to the current state in Spark is that the framework in Flink is already authentication protocol agnostic (and not bound to Kerberos).
Documentation #
For more details please refer to the following documentation:
Development details #
Major tickets where the framework has been added:
- FLINK-21232 Kerberos delegation token framework
- FLINK-29918 Generalized delegation token support
- FLINK-30704 Add S3 delegation token support
Example implementation #
Adding a new authentication protocol is relatively straight-forward:
- Check out the example implementation
- Change
FlinkTestJavaDelegationTokenProvider.obtainDelegationTokens
to obtain a custom token from any external service - Change
FlinkTestJavaDelegationTokenReceiver.onNewTokensObtained
to receive the previously obtained tokens on all task managers - Use the tokens for external service authentication
- Compile the project and put it into the classpath (adding it inside a plugin also supported)
- Enjoy that Flink does all the heavy lifting behind the scenes :-)
Example implementation testing #
The existing providers are tested with the Flink Kubernetes Operator but one can use any other supported deployment model, because the framework is not bound to any of them. We choose the Kubernetes Operator so that we could provide a completely containerized and easily reproducible test environment.
An example tutorial can be found here on external system authentication.
Summary #
The Delegation Token Framework is feature complete on the master branch and is becoming generally available on the release of Flink 1.17. The framework obtains authentication tokens at a central location and propagates them to all workers on a re-occurring basis.
Any connector to an external system which supports authentication can be a potential user of this framework.
To support authentication in your connector we encourage you to implement your own DelegationTokenProvider/DelegationTokenReceiver
pair.

Dear Gecode gurus,
I'm currently tracking down some memory leaks that occur when I'm using
Gecode. I have custom propagators and branchings, and both have some
non-trivial members (vectors and other data structures). What surprised
me was that nobody calls the destructors of the vectors, and what's
more, not even the destructors of the actors. Then I remembered seeing
something about dispose() in Gecode 1.2.0 changelog. I ended up calling
the members' destructors explicitly in dispose(). Is this the correct
approach, or am I missing something?
Thanks,
Filip

Chicago's public housing developments mostly center around the west side and south side of chicago.
Paris' public housing developments mainly are focused around the outskirt neighborhoods of Paris. But are more evenly distributed throughout the city and not all lumped into a couple of neighborhoods.
In the chart, is the calculated total of all public housing individual units for both major cities. Where the maps take the total amount of developments, those developments can include more than one, and often many, different individual units. Here you can see the large deficet in the total amount of public housing units in Chicago in comparison to Paris.

My Skillset
I know languages like C++, Python, JavaScript, Verilog and ROS. I also know a lot of python libraries like Keras and PyTorch which I very often use for Machine Learning Purposes, Pandas, Numpy, Scikit, etc. I have a diverse set of skills from design to Semantic and well structured HTML + reasonable and efficient CSS + JS + React ( for building complex UIs ). I love things that are open source I use VS Code as my editor and Windows and Ubuntu as My operating system.
My WorkAbout Me
I am a 3rd year Undergraduate studying in Indian Institute Of Technology, Kanpur since 2019. Some of my interests include Machine Learning and App Development. I like coding a lot, but what I like more is perhaps meeting new people! So, if anyone is here, feel free to reach out to me!
My Craft in a Nutshell
I love simplicity so I try my best to make things as simple as possible. I am also very concerned about best practices and always sacrifice developer experience over user experience.
Hackathon Gendered Pronoun Resolution
Pronoun resolution is part of coreference resolution, the task of pairing an expression to its referring entity. This is an important task for natural language understanding, and the resolution of ambiguous pronouns is a longstanding challenge. Solution write-up is at: A Simple Bert Model
Style Transfer using Pytorch
I used Pytorch to transfer ”style” of one image to another. I used a pretrained 19 layer VGG model and then used outputs of different convolutional layers to grab deatails within the image.
Detecting And Tackling Bias in Machine Learning Models (Ongoing)
The initial approach focuses on predicting the age and gender based on images of faces, with the academic goal of implementing exploring bias in image classification.
My Work
I have tried my hands on a lot of things during my two years at IIT Kanpur. I've been quite involved in learning about newer advancements in Machine Learning and Neural Networks in general. Recently, I've started exploring out and learning React for Frontend Development. Other than coding, I am also an Academic Mentor for the course MTH101/102 in IITK and also Manager, Campus, Outreach Cell.

Our original model. Still the best small pillow that doubles as a delicious snack.
The Croissant Pillow, now extra comfy. Thats what XC stands for. And the plus? Now the pillows even bigger.
The Croissant Pillow now featuring a phone charger. And a battery that charges itself whenever you take a bite. Still as comfy as the Plus XC. And we made it a little bit bigger, with the biggest size now 15 feet long!
The biggest change to the Croissant Pillow, since the croissant pillow. Featuring more features than you have legs, unless you've been sunbathing in Chernobyl. With the new massive model measuring just under 4 miles wide. Don't ask how we ship. Just remember it isn't free.

Habitat
It is not known for sure, but the Meows can live everywhere. They can live even in cities where they often settle in garbage dumps and in attics, but most often Mautov can be found in dark alleys where they take their victim by surprise. But in Yunovo this pokemon does not occur.


I can trust people to only do what they’re supposed to
People who believe this misconception think that trust in users (e.g., local people in an organization and/or remote
users of a program or system) is a valid replacement for robust security controls. However, this idea breaks down
whenever any person takes an action that violates this assumption, either intentionally (they are a bad actor) or
unintentionally (they make a mistake). In essence, this misconception is not following the principle of least
privilege, which says that people should get no more than the minimum permissions necessary to accomplish their
tasks. Taking away any additional permission should break the system. A good way of building policies like this is
to start from no permission (“deny by default”) and then add only necessary permissions (privileges, features, etc.)
until the system works as required. Following this principle can avoid both malicious unauthorized access and
accidents.

We provide multiple options for displaying our tile data across multiple platforms.
Using our JavaScript client library is the recommended way of displaying our tiles for web clients. It provides a easy to use API for drawing maps with custom marker and location data. See the PolarMap.js API for more details.
Our v1.0 tiles are compatible with Leaflet maps, when used with the Proj4JS and Proj4Leaflet libraries.
OpenLayers has support for projected tiles, and can easily be modified to display our Arctic Web Map tiles. It has excellent support for accessing tiles via XYZ (OpenStreetMap style) or via WMTS.
The original set of Arctic Web Map tiles generated from 2015 to 2017 and supporting multiple arctic projections can be used directly with compatible clients.
The URL template for our tiles is http://tiles.arcticconnect.ca/osm_{projection}/{z}/{x}/{y}.png
where {projection}
is one of 3571, 3572, 3573, 3574, 3575 or 3576,
{z}
is the zoom level,
{x}
is the tile x-index,
and {y}
is the tile y-index.
This follows the informal OpenStreetMap tile server naming scheme.
The newer set of Arctic Web Map tiles generated from 2019 OpenStreetMap data can be used directly with compatible clients.
The URL template for our tiles is http://tiles.arcticconnect.ca/awm/{z}/{x}/{y}.png
where {z}
is the zoom level,
{x}
is the tile x-index,
and {y}
is the tile y-index.
This follows the informal OpenStreetMap tile server naming scheme.
Clients compatible with the Open Geospatial Consortium WMTS standard can access the v2.0 tiles using one of the following Capabilities documents.
Accessing v2.0 tiles via WMTS or XYZ will use the same source OSM data, and tiles are rendered to images using Mapnik, therefore the map should look nearly identical when accessed via WMTS or XYZ.

Ariana Grande set to axe tour dates after being left 'in so much pain'
Grande, 26, says in videos posted on Instagram that "my throat and head are still in so much pain."
by James Rodger, https://www.facebook.com/jamesrodgerjournalistAriana Grande has told fans she has a bad sinus condition that has made her "very sick" and might force her to cancel shows on her forthcoming world tour.
Grande, 26, says in videos posted on Instagram that "my throat and head are still in so much pain."
"I sound okay I'm just in a lot of pain and it's difficult to breathe during the show," she says. "I just really don't know what's happening with my body right now and need to figure it out."
Grande says she plans to see a doctor soon.
She adds: "I'm scared that I might have to cancel some things, so this is kind (of) just a heads up of like I don't know what's happening with my body, and I'm really disappointed and freaked out of why I can't get better because it's been over three weeks at this point."


EU to subsidise private storage of virgin olive oil
The European Commission has adopted an exceptional aid package for private storage of virgin olive oil to balance markets, marked by falling prices for the product, notably in Portugal and Spain.
“Given an oversupply following the 2018-2019 harvest, prices on the Spanish, Greek and Portuguese markets have been particularly low,” said the European Commission in a statement.
Markets are being affected by the sharp fall in prices in Spain, the largest producer and exporter of olive oil, where extra virgin olive oil prices were 33 percent below the five-year average in mid-October.
By comparison, in Greece olive oil was marketed at a price 13.5 percent below the five-year average.
In April, the average price of virgin olive oil in the European Union (EU) was the lowest since October 2014, at €265 per 100 kilograms, 14 percent less than in the same month last year.
The EU forecasts an increase in stocks of 859,000 tonnes of olive oil in the 2018/2019 marketing year, with 88 percent coming from Spain, which, combined with the expectation of a harvest in 2019/2020 threatens the European market, hence the need for intervention.
Contracts for private storage aid cover a period of 180 days.
Virgin olive oil producers from Portugal, Spain, France, Greece, Italy, Croatia, Cyprus, Malta and Slovenia can apply.

#assign l2caching_overview="active">
The goal of the L2 cache is to gain very significant performance improvement by not having to hit the database to read some information.
For example, instead of performing a "find by id" or "find by unique key" query we can get Ebean to effectively lookup the result in the L2 cache. If we are using near caching then this might often result in an in-memory lookup into a local Map and not even require a remote call so be very fast.
It is called the "Level 2 cache" because the persistence context is often referred to as the "Level 1 cache".
The "L2 cache" has 2 main caches – "Bean caches" and "Query caches".
Bean caches hold entity beans and are keyed by their Id values and optionally also by their natural key. The bean cache can be used with:
Query caches hold the results of queries (Lists, Sets, Maps of entity beans and Count) and are keyed by a hash of the query and its bind values.
The entries in a query cache are invalidated by ANY change to the underlying table – insert, update or delete. This means that the query cache is generally only useful on entities that are relatively infrequently modified (typically "lookup tables" such as countries, currencies, status codes etc).
The query cache can be used with:
Ebean L2 caching uses eventual consistency.
This means it operates a bit like "replication lag". Data returned from the L2 cache can be (milliseconds) out of date. Changes will be made to the cache in a relatively short time (milliseconds) but there isn't the gauruntee of read consistency that our transactional database provides.
With Ebean L2 caching there is no attempt to provide transactional read consistency. If part of an application needs transactional read consistency then we should use the database to do that.
Ebean will automatically invalidate the cache when beans are persisted or update queries are executed.
In addition we can explicitly invalidate parts of the cache programmatically.
By default Ebean will perform L2 cache updates and invalidation in the background. If we want cache updates and
invalidation to execute in the foreground then we need to set notifyL2CacheInForeground
to true.
A cache that runs in the same process as Ebean is a Near cache. Performing a hit against a near cache is an in-memory Map lookup and does not go over the network. Hits against a near cache are very fast - it's effectively a local in-memory Map get().
Ebean L2 bean caches for Redis, Hazelcast and Ignite all have a Near cache option. When this is enabled then there is a local in-process cache that is used and hit first, and then only if there is a miss on the near cache does the request go to the remote Redis | Hazelcast | Ignite cache.
For example, using ebean-redis with bean caching on Customer with near cache enabled:
@Cache(nearCache=true) @Entity public class Customer
Note that all Query caches are implemented as near cache only.
We use "Regions" to group caches so that we can enable and disable L2 caching by "region groups".
This provides a mechanism where we can "feature toggle" / enable L2 caching by named regions.
Let's say our application rolls out, and it uses L2 caching for Product (and we call that region "product-region"). Now, we develop further and as part of that want to use L2 caching for Price but, we don't yet want to enable that in all environments (e.g. we don't want it enabled in production). In dev and test we might enable the l2 cache regions "product-region,price-region" but in production only enable "product-region".
@Entity @Cache(region = "product-region") public class Product
ebean.enabledL2Regions=product-region,price-region

| disableL2Cache | false | Set to true to globally disable L2 caching |
| enabledL2Regions | Set the enabled L2 cache regions (comma delimited). By default all regions are enabled. | |
| localOnlyL2Cache | false | Set to true to effectively disable L2 cache plugins (like ebean-redis, ebean-hazelcast) |
| notifyL2CacheInForeground | false | Set to true for cache notifications and invalidation to run in the foreground. Generally we want to perform L2 cache notification in the background and not impact the performance of executing transactions. |

An interface offering of the Builder pattern for creating Java Future references to FSDataInputStream and its subclasses. It is used to initate a (potentially asynchronous) operation to open an existing file for reading.
The FSDataInputStreamBuilder interface does not require parameters or or the state of FileSystem until build() is invoked and/or during the asynchronous open operation itself.
Some aspects of the state of the filesystem, MAY be checked in the initial openFile() call, provided they are known to be invariants which will not change between openFile() and the build().get() sequence. For example, path validation.
A FileStatus instance which refers to the file being opened.
This MAY be used by implementations to short-circuit checks for the file, So potentially saving on remote calls especially to object stores.
Requirements:
The path validation MUST take place if the store uses the FileStatus when it opens files, and MAY be performed otherwise. The validation SHOULD be postponed until the build() operation.
This operation should be considered a hint to the filesystem.
If a filesystem implementation extends the FileStatus returned in its implementation MAY use this information when opening the file.
This is relevant with those stores which return version/etag information, including the S3A and ABFS connectors -they MAY use this to guarantee that the file they opened is exactly the one returned in the listing.
FSDataInputStreamBuilder opt(String key, ...) FSDataInputStreamBuilder must(String key, ...)
Set optional or mandatory parameters to the builder. Using opt() or must(), client can specify FS-specific parameters without inspecting the concrete type of FileSystem.
out = fs.openFile(path) .opt("fs.s3a.experimental.input.fadvise", "random") .must("fs.s3a.readahead.range", 256 * 1024) .withFileStatus(statusFromListing) .build() .get();
Checking for supported options must be performed in the build() operation.
If a mandatory parameter declared via must(key, value)) is not recognized, IllegalArgumentException MUST be thrown.
If a mandatory parameter declared via must(key, value)) relies on a feature which is recognized but not supported in the specific Filesystem/FileContext instance UnsupportedException MUST be thrown.
The behavior of resolving the conflicts between the parameters set by builder methods (i.e., bufferSize()) and opt()/must() is as follows:
The last option specified defines the value and its optional/mandatory state.
If the FileStatus option passed in withFileStatus() is used, implementations MUST accept all subclasses of FileStatus, including LocatedFileStatus, rather than just any FS-specific subclass implemented by the implementation (e.g S3AFileStatus). They MAY simply ignore those which are not the custom subclasses.
This is critical to ensure safe use of the feature: directory listing/ status serialization/deserialization can result result in the withFileStatus() argumennt not being the custom subclass returned by the Filesystem instance’s own getFileStatus(), listFiles(), listLocatedStatus() calls, etc.
In such a situation the implementations must:
Return an CompletableFuture<FSDataInputStream> which, when successfully completed, returns an input stream which can read data from the filesystem.
The build() operation MAY perform the validation of the file’s existence, its kind, so rejecting attempts to read from a directory or non-existent file. Alternatively, the build() operation may delay all checks until an asynchronous operation whose outcome is provided by the Future
That is, the precondition exists(FS, path) and isFile(FS, path) are only guaranteed to have been met after the get() on the returned future is successful.
Thus, if even a file does not exist, the following call will still succeed, returning a future to be evaluated.
Path p = new Path("file://tmp/file-which-does-not-exist"); CompletableFuture<FSDataInputStream> future = p.getFileSystem(conf) .openFile(p) .build;
The preconditions for opening the file are checked during the asynchronous evaluation, and so will surface when the future is completed:
FSDataInputStream in = future.get();

Childhood
I was born on a warm autmn day of September 9th, 1994. After awaking from my sleep, I was thrust into life against my will. So, I decided that instead of complaining about it I would try to make my life the best it could be. Over the course of my childhood I played soccer, football, was always good at math, liked history, and played computer games. Towards the end of high school, I was doing PSEO(Post Secondary Enrollment Option) which allowed me to take classes at the local community college for free. This helped me pursue a love for math and computers even more as my high school had limited offerings.
College
Fast-foward to college, I majored in Math and Physics initially, but something happened that made me lose interest in physics. I couldn’t tell you what but I just had no desire to take those classes at all. I was lost in what I wanted to do, with my focus on math being the sole thing that carried me in my studies. During that time of self-discovery I stumbled upon a book that made me see the light, it was none other than Freakanomics. This book brought to my attention the usefulness of being able to use data to convince a reader of the hypthesis in question. I was hooked. Over the next 2 years in college I continued taking math with a focus on applied math, and also jumped into economics as that was the only major that really allowed me to explore using data and math to show conclusions.
Graduate School
Graduate school was next on the list and I knew I didnt want to attend a PhD program, but I did want to continue my quest of data science. Which lead me to the applied economics program at UND(Universtiy of North Dakota), which is where I attended undergraduate as well. This program really allowed me to jump into my data driven studies and showed me a lexicon of methods that I could use. The problem was, they used an ancient program called stata. This is a commonly used language in economics and nothing else. It is a horrible language that is also licensed. This lead me to wanting to use a different language. A better language. One where the people who use it also make the packages. This is R.
Professional Life
in my search for a job after graduate school I started working at IBM in Rochester, MN as a Financial Data Scientist. This entailed a lot of work with financial time series data. Along with building out modeling algorithms, I had to learn how to deploy things on the cloud, using docker and kubernetes as the modalities for that.  After leaving IBM, I joined the contractual team at C.H. Robinson and am focused on time-series and the engineering side of things there. It is a blast.
