How to Play Capitalism
Four Parts:Setting Up the GamePlaying the First RoundPlaying the Next RoundsAdding a Twist to the GameCommunity Q&A
Capitalism is a fun game for a group of three or more. It is based on the Japanese card game Dai Hin Min. Capitalism is also known as Scum, President, or Kings. The goal of the game is to rise above your peers by eliminating all of your cards first to avoid becoming "scum."
Steps
Part 1Setting Up the Game
1
Shuffle a deck of cards. You'll need a deck of 52 regular playing cards. For the first time playing, remove the Joker card from the deck. The values of the cards running lowest to highest are 2-10, Jack, Queen, King, and Ace.
2
Start out with four people. You can always add more players but you need a minimum of four players. This is because once the first round is over, each person will be given a ranking: President, Vice President, Vice Scum, and Scum.[1]
The ranking names vary across the world.
Variations can include anything that is based on a hierarchy such as Boss, Manager, Worker, Scum.
If there are more than four players, add new name rankings like Secretary, Middleman, or Citizens.
3
Pick a dealer. Have everyone draw a card from the deck. The lowest card value will be the dealer. Put the cards back in the deck once the dealer is picked.
To determine the order of the game you have a few options. You can take turns going in a circle starting from the left of the dealer. Or instead, the lowest card is the dealer, the next highest card is the first person to start a trick and on through and the last person goes last. If you choose the latter option, have everyone sit in order of when their turn is.
4
Deal out all of the cards. Have the dealer give each person one card and continue going in a circle giving people cards one by one until the deck has been given away. A round will end when everyone has gotten rid of their cards and the deck is restored to 52 cards.
Part 2Playing the First Round
1
Have the first person lay down a card. This is the beginning of a "trick." Rounds are made up of tricks, where the goal is to get rid of as many cards as you can and quickly. The person to start a trick must lay down anything higher than a 2 to begin.
2
Put down a higher card than what person 1 played. Going around in a circle, each person takes a turn laying down one or more cards of a higher value. You cannot match the played card's value, it has to "beat" the card that played on by the previous person.
You can't put down two cards of unequal value, they must be exact pairs. For example, if a 4 is on the table, you can't put down a 5 and 7 but two 6's will work.
3
Play until no one can beat the card on the table. Eventually everyone will begin to run out of higher valued cards that can beat what's on the table. When someone is out of playable cards, they pass on every one of their turns until everyone else has to pass.
You can pass even if you have cards that can be played.
Passing can be strategic, for instance
Passing on one turn does not mean that you forfeit any other turns. It just means that you have to wait until the next go around.[2]
4
End a trick when no one can play anymore cards. As the game play continues, the dealer collects the piles of cards and sets them aside to start the new deck for the next round. To start the next trick, the last person who laid a card down in the previous trick lays down a card to begin the next one.
5
Keep playing through tricks until someone runs out of cards. The first person to get rid of all of their cards will be named President. The next person is the Vice President, the next is Vice Scum, and the last person with cards is Scum.[3]
Part 3Playing the Next Rounds
1
Reshuffle the deck. The person who was named Scum in the last round is the dealer for this round and also collects each pile when a trick is finished. Because there may be some numerical runs of cards or doubles and triples may have been played, the deck needs to be reset.
2
Rearrange seats so that the seating order is ranked. Everyone should be seated in ranked order, so if the group is in a circle, the President should be sitting next to Scum. In many variations of the game, the President is rewarded with the comfiest chair in the house and the Scum is relegated to the most uncomfortable spot.[4]
3
Start a new round. Before play continues, Scum must give the President their two highest cards and the President can give Scum any two cards they choose.[5]
4
Begin playing the next trick with the player to the dealer's left. This will always be the Vice Scum, as the Scum will always be the dealer. Now, the rankings will change each round as different people will discard their hands faster and earn the title of President. But what's consistent is that the Scum does the grunt work of dealing and clearing the table after tricks.
5
Keep track of points as the rounds continue. In order to prevent the game for stretching on forever, award the President 2 points, the Vice President 1 point, and everyone else none every time they earn that ranking at the end of a round. Aim for a goal of 11 points for example so that the game has an ending point.[6]
6
Continue playing rounds until someone reaches 11 points. This will be the end of the game if you're playing based on points. If not, the game can last much longer or you can start a totally new game, where again you are aiming for 11 points to win.
Part 4Adding a Twist to the Game
1
Add another deck of cards. This increases everyone's chances of getting higher cards. But more importantly, it introduces the option for more doubles and also triples and quadruples.
Triples are three of the same value card, not suit type. If a triple is played by one person, the next person must mirror the same amount of cards (three) and beat the card value. For example, the first person plays three 6s. The next person must play three 7s or three of a higher value or pass.
Quadruples operate by the same logic as triples, it's just much more difficult.[7]
2
Add the joker card into the game. Jokers can be used for many functions. They can be treated as a wild card, equaling any value card, if you decide to use that rule. They can also clear a trick. If someone plays a Joker, that trick is done and Scum clears away the stack of cards.[8]
3
Use 2s or 8s to clear a trick. Like a Joker, a 2 or an 8 can be played to clear a trick. However, an 8 can only be played over a lower-valued card, such as a 6 or a three. An 8 cannot clear a trick when played over a 10 for instance.
4
Introduce alcohol to spice things up. Capitalism is commonly played as a drinking game and there a couple of different rules that can be added to make the game a little more fun:
Anytime a card value is played that equals the amount of players (i.e. a 4 of diamonds and four players or a 6 of clubs for 6 players), then everyone takes a drink.
If a player passes their turn, they have to take a drink.
If one player puts down the same value card as what is on the pile, then the next person is skipped and a skipped person has to take a drink.<refhttp://www.gutenberg.us/articles/capitalism_(card_game)</ref>

Library for converting ImageResource objects into various file format encodings.
Encodes an ImageResource or a series of ImageResources into a list of bytes using the ICO format.
Creates a new Icon encoder. By default the icon encoder contains no images. As it supports multiple images at different resolutions, each must be added using addImage.
Adds an image to the icon file. The image will be padded and/or resized to fit the most appropriate resolution for .ico formats. Icon files support the following sizes: 16x16, 32x32, 64x64, 128x128, and 256x256. When an image is added that does not adhere to one of those sizes, it is converted to the largest size that it can fit into by adding invisible padding (it will be centered). If it is larger than 256x256, it will centered and cropped. Only one image is supported per size bucket. Images added that apply to an identical size buckets that a previous image was added to will be overwritten in the final output.

This library is a wrapper around the http://www.public-software-group.org/utf8procutf8proc library, providing information about Unicode code-points and performing operations (mappings) on Unicode atoms. The central predicate is unicode_map/3, mapping a Unicode atom to another Unicode atom using a sequence of operations.

◆ I2C_NO_REG
| #define I2C_NO_REG ( 1 << 30 ) |
Used when the I2C peripheral does not use registers for read/write operations.
This macro is used in situations when the I2C peripheral connected to port A does not use registers to perform read or write operations to it. Since register addresses are uint8, this 32-bit value exceeds the range of possible register addresses and is used to trigger logic to bypass the write to the register address.
◆ I2CDevice_t
A pointer to the I2C peripheral configuration.
Contains configuration related to the peripheral in the following structure:
- addr (device address)
- i2c_port
- port (I2C port number — 0 or 1)
- sda (I2C port's SDA pin)
- scl (I2C port's SCL pin)

Ronaldo on target to beat Ali Daei’s World Record
by Mir Farhad Ali KhanTasnim – TURIN, Portugal striker Cristiano Ronaldo insisted that breaking Ali Daei’s record for international goals is on the cards.
The 34-year-old forward took his tally of international goals to 99 with a late tap-in as Portugal secured a place at Euro 2020 with a labored 2-0 win over Luxembourg on Sunday.
Ronaldo is now just 10 goals behind the highest international goalscorer of all time – Iran legend Daei.
And he insists breaking Daei’s record is on the cards.
“All records must be broken and I will beat that record,” said Ronaldo after the match.


About twenty minutes after that call, I received another one. Grand Central Station today.
"Doctor Green?"
"This is he."
"Doctor, this is Reverend Wallach of the Coalition for Preservation of Family & Society. Do you have a minute to talk?"
"Sure." I thought for a second, who? What? Then it hit me. This was the Christine Wallach. Executive Director for the CPFS, a religious alliance of Christians, Jews, and Moslems. One of the most powerful political groups in North America with a membership list and organization larger than that of the National Weapons Association. One of the most powerful women in all of North America.
"Excellent. I must say, Doctor, that I had a rather difficult time finding anyone in your corporation who would talk to me."
"Well, they're just afraid of you, I guess."
Her laughter pealed out over the phone clearly, as water might gush forth from a fountain. "But you, Doctor, you're not afraid of me?"
"I fear nothing but the judgment of the Almighty, Ms. Wallach."
"Ah, well spoken." She was all serious business. "You're a God-fearing man, then?"
"No. I'm a God-loving man."
"Ah. Some would say they are one and the same. Well, I must say, this surprises me. I did not expect to find someone who spoke my language."
"English?"
"No, I meant . . . well, never mind. How is it that you countenance what your corporation is doing?"
"Let me guess. In reference to our virtual city simulation?"
"Yes. How can you, of all people, allow such filth on the Internet?"
"Ms. Wallach, filth was on the Internet long before I even had a job with this corporation. Filth existed long before there was an Internet. But anyway it's not a question of whether I should allow it or not. Are you aware of our referendum process?"
"Not precisely, no."
"Well, in short, I don't tell people what they can see or not, I just call a referendum for the people to decide whether a particular site should be listed in our listings. Think of our virtual city as a big Yellow Pages where the customers on the mailing list choose which phone numbers they want to be listed. It's that simple."
"Sometimes people don't always know what is right; they need guidance."
"Like children? I suppose that's true in some circumstances. Almost all of the people who access the virtual city are over five years of age, however."
"Why expose people to such perversion, though? This is not something your corporation should be doing."
"Even if we pulled the link, Ms. Wallach, the perversion would still be there."
"But you don't have to make it easy for people. You should pull the link."
"I just got off the phone with Roberto Canseco. He insisted that I not pull the link."
"That man is the devil's spawn."
"I wouldn't know."
"We are very much against this," she warned.
"Well then I have a suggestion for you. And if you say the idea came from me, I'll deny it."
A short pause. "I'm listening."
"The CPFS favors preservation of family and social values within the framework of democracy, right?"
"Democracy. Go on."
"Okay, I'll take that as a yes. So what you might consider doing is asking your membership to get on their computers and access the virtual city, and become citizens of the virtual city. They would instantly have the right to vote on the referendum. You could tell them all to vote yes in favor of banning the site."
"Would that get rid of it?"
"Well, it would give me the authority to remove the listing. It would disappear from the virtual city. But the files would still be available on the Internet."
"But your corporation provides Internet access all around the globe, so how does that solve the problem?"
"It doesn't," I said honestly. "The problem isn't about technology but about morality, which is a bigger issue. All I can do, to use your own words, is not make it easy for people. Force them to go outside the virtual city using a different browser."
"A what?"
"Software. In other words, make it inconvenient to switch from one pair of glasses to another. Most people don't like doing that."
"I see your point. So what you're saying is, that we can affect the outcome through force of numbers?"
"Yes."
"Create a virtual City of God?"
"Become the new St. Augustine, if you like."
"It's an interesting idea, Doctor. I'll consider it. Thanks."
"Don't thank me; it's your idea."
She laughed. "Right. Well, thank you for your time. God be with you."

The ATLAS experiment is an enormous collaboration of over 3000
scientists from around 40 countries
interested in studying the millions of proton-proton collisions
produced by the Large Hadron Collider (LHC) at CERN in Geneva, Switzerland.
To do that they built one of the largest and most complex machines in the world.
Weighing about as much as the Eiffel Tower and standing as tall the Notre Dame
Cathedral in Paris, it's like a giant 100 million pixel camera with a shutter speed capable
of taking a picture 40 million times a second
and with a resolution on the order of microns. It's an impressive machine!
The picture above is of a mural painted of the detector outside the ATLAS control room.
Although, the real thing may be even more beautiful.
I've spent the last 6 years working on the ATLAS Experiment. Most of that time
I was looking at the petabytes of proton-proton collision data collected by the experiment.
You might recall the famous
discovery of the Higgs boson announced on July 4th, 2012 - Higgs-dependence day.
Well, there's me watching the big announcement! (I seem to have made it into an Italian newspaper.)
That was a once in a lifetime discovery.
But the data used to make the discovery is very rich and so can be looked at in myriad ways.
Some analyses of the data attempt to discover other new particles besides the Higgs;
other analyses use the data to better understand the performance and behavior of the machine itself;
still others seek to test the validity of our current best description of the universe, the so-called
Standard Model. I have been involved in analyses of each kind.
Searching for the W-prime
In one analysis
we were looking for signatures of an exotic particle called the W-prime.
The W-prime is only
theorized to exist, and if it did then it could be a clue to an entirely unexplored realm beyond the Standard Model.
Which would be even more exciting than the Higgs discovery!
We compared the data to what we would expect if the only the Standard Model were true (the null hypothesis)
and if the W-prime signal were added in on top of that (the alternative hypothesis). You can see a plot of just such a comparison
as a function of the most interesting discriminating variable.
The data is in black, while the standard model prediction is shown in the solid stacked histograms and the proposed signals
are drawn on top as individual lines. As you can see, the data agrees really well with the Standard Model and has no need
for the proposed signal. So we looked and didn't find it.
But you should have expected that because if we had you would have heard about it and I would be in the running for the Nobel Prize.
Studying the Muon Trigger system
In another analysis
we studied the performance of an online data filtering system called the trigger system.
The data comes in so fast from the LHC that there is no way to record it all, so the trigger system uses a combination of
fast electronics and computing clusters to make on the fly decisions about which data is the most interesting. In particular,
we focused on collisions that produce a very special (and my favorite) particle called the muon, which is like the electron's
obese cousin. As you can imagine, this system is incredibly important to understand. If it's not designed properly we could
throw out all of our interesting data without getting a chance to look at it! Fortunately, we understand the trigger system
very well.
Measuring WWW production
Last but not least, in my thesis analysis we used the data to observe for the first time
a process that was predicted by the Standard Model but until the now haven't had a machine that would allow
us to be sensitive to it. This is a peculiar phenomenon known as WWW or tri-W production. The Standard Model
predicts a particle called the W boson which was discovered at CERN way back in 1983
and which won Carlo Rubbia and Simon van der Meer the Nobel Prize. Back then they made the discovery using
just a couple of collisions where they observed the production of the W boson on its own. Now, in the modern
era of the LHC single W bosons are produced in copious amounts. But W bosons can also be produced as twins or as triplets
or in conjunction with other particles, it's just way less likely. And the details of those phenomena, like the rate
at which they occur, has important consequences for the Standard Model. Others have looked at many of these production
mechanisms, but none had ever before attempted to look at the production of three W bosons simultaneously.
A particle physicist would represent this process using a Feynman Diagram like this:
where the protons come in from the left and the three W bosons come out on the right.
Being the first to look for this type of process presented unique challenges for understanding and interpreting the data,
which I was involved deeply in every step of the way.
At this moment, the results of the analysis aren't public, but they should be in the next month or two at which point I will
go into detail about the analysis. Stay tuned...

16.5 Shelve FilesPickling allows you to store arbitrary objects on files and file-like objects, but it's still a fairly unstructured medium; it doesn't directly support easy access to members of collections of pickled objects. Higher-level structures can be added, but they are not inherent:
Shelves provide some structure to collections of pickled objects. They are a type of file that stores arbitrary Python objects by key for later retrieval, and they are a standard part of the Python system. Really, they are not much of a new topic -- shelves are simply a combination of DBM files and object pickling:
Because shelve uses pickle internally, it can store any object that pickle can: strings, numbers, lists, dictionaries, cyclic objects, class instances, and more. 16.5.1 Using ShelvesIn other words, shelve is just a go-between; it serializes and deserializes objects so that they can be placed in DBM files.  Your scripts never see all this interfacing, though. Like DBM files, shelves provide an interface that looks like a dictionary that must be opened. To gain access to a shelve, import the module and open your file: import shelve dbase = shelve.open("mydbase") Internally, Python opens a DBM file with name mydbase, or creates it if it does not yet exist. Assigning to a shelve key stores an object: dbase['key'] = object Internally, this assignment converts the object to a serialized byte-stream and stores it by key on a DBM file. Indexing a shelve fetches a stored object: value = dbase['key'] Internally, this index operation loads a string by key from a DBM file and unpickles it into an in-memory object that is the same as the object originally stored. Most dictionary operations are supported here, too: len(dbase) # number of items stored dbase.keys( ) # stored item key index And except for a few fine points, that's really all there is to using a shelve. Shelves are processed with normal Python dictionary syntax, so there is no new database API to learn. Moreover, objects stored and fetched from shelves are normal Python objects; they do not need to be instances of special classes or types to be stored away. That is, Python's persistence system is external to the persistent objects themselves. Table 16-2 summarizes these and other commonly used shelve operations.
Because shelves export a dictionary-like interface, too, this table is almost identical to the DBM operation table. Here, though, the module name anydbm is replaced by shelve, open calls do not require a second c argument, and stored values can be nearly arbitrary kinds of objects, not just strings. You still should close shelves explicitly after making changes to be safe, though; shelves use anydbm internally and some underlying DBMs require closes to avoid data loss or damage. 16.5.2 Storing Built-in Object TypesLet's run an interactive session to experiment with shelve interfaces: % python >>> import shelve >>> dbase = shelve.open("mydbase") >>> object1 = ['The', 'bright', ('side', 'of'), ['life']] >>> object2 = {'name': 'Brian', 'age': 33, 'motto': object1} >>> dbase['brian'] = object2 >>> dbase['knight'] = {'name': 'Knight', 'motto': 'Ni!'} >>> dbase.close( ) Here, we open a shelve and store two fairly complex dictionary and list data structures away permanently by simply assigning them to shelve keys. Because shelve uses pickle internally, almost anything goes here -- the trees of nested objects are automatically serialized into strings for storage. To fetch them back, just reopen the shelve and index: % python >>> import shelve >>> dbase = shelve.open("mydbase") >>> len(dbase) # entries 2 >>> dbase.keys( ) # index ['knight', 'brian'] >>> dbase['knight'] # fetch {'motto': 'Ni!', 'name': 'Knight'} >>> for row in dbase.keys( ): ... print row, '=>' ... for field in dbase[row].keys( ): ... print ' ', field, '=', dbase[row][field] ... knight => motto = Ni! name = Knight brian => motto = ['The', 'bright', ('side', 'of'), ['life']] age = 33 name = Brian The nested loops at the end of this session step through nested dictionaries -- the outer scans the shelve, and the inner scans the objects stored in the shelve. The crucial point to notice is that we're using normal Python syntax both to store and to fetch these persistent objects as well as to process them after loading. 16.5.3 Storing Class InstancesOne of the more useful kinds of objects to store in a shelve is a class instance. Because its attributes record state and its inherited methods define behavior, persistent class objects effectively serve the roles of both database records and database-processing programs. For instance, consider the simple class shown in Example 16-2, which is used to model people. Example 16-2. PP2E\Dbase\person.py (version 1)# a person object: fields + behavior class Person: def __init__(self, name, job, pay=0): self.name = name self.job = job self.pay = pay # real instance data def tax(self): return self.pay * 0.25 # computed on call def info(self): return self.name, self.job, self.pay, self.tax( ) We can make some persistent objects from this class by simply creating instances as usual, and storing them by key on an opened shelve: C:\...\PP2E\Dbase>python >>> from person import Person >>> bob = Person('bob', 'psychologist', 70000) >>> emily = Person('emily', 'teacher', 40000) >>> >>> import shelve >>> dbase = shelve.open('cast') # make new shelve >>> for obj in (bob, emily): # store objects >>> dbase[obj.name] = obj # use name for key >>> dbase.close( ) # need for bsddb When we come back and fetch these objects in a later Python session or script, they are recreated in memory as they were when they were stored: C:\...\PP2E\Dbase>python >>> import shelve >>> dbase = shelve.open('cast') # reopen shelve >>> >>> dbase.keys( ) # both objects are here ['emily', 'bob'] >>> print dbase['emily'] <person.Person instance at 799940> >>> >>> print dbase['bob'].tax( ) # call: bob's tax 17500.0 Notice that calling Bob's tax method works even though we didn't import the Person class here. Python is smart enough to link this object back to its original class when unpickled, such that all the original methods are available through fetched objects. 16.5.4 Changing Classes of Stored ObjectsTechnically, Python reimports a class to recreate its stored instances as they are fetched and unpickled. Here's how this works:
The key point in this is that the class itself is not stored with its instances, but is instead reimported later when instances are fetched. The upshot is that by modifying external classes in module files, we can change the way stored objects' data is interpreted and used without actually having to change those stored objects. It's as if the class is a program that processes stored records. To illustrate, suppose the Person class from the previous section was changed to the source code in Example 16-3. Example 16-3. PP2E\Dbase\person.py (version 2)# a person object: fields + behavior # change: the tax method is now a computed attribute class Person: def __init__(self, name, job, pay=0): self.name = name self.job = job self.pay = pay # real instance data def __getattr__(self, attr): # on person.attr if attr == 'tax': return self.pay * 0.30 # computed on access else: raise AttributeError # other unknown names def info(self): return self.name, self.job, self.pay, self.tax This revision has a new tax rate (30%), introduces a __getattr__ qualification overload method, and deletes the original tax method. Tax attribute references are intercepted and computed when accessed: C:\...\PP2E\Dbase>python >>> import shelve >>> dbase = shelve.open('cast') # reopen shelve >>> >>> print dbase.keys( ) # both objects are here ['emily', 'bob'] >>> print dbase['emily'] <person.Person instance at 79aea0> >>> >>> print dbase['bob'].tax # no need to call tax( ) 21000.0 Because the class has changed, tax is now simply qualified, not called. In addition, because the tax rate was changed in the class, Bob pays more this time around. Of course, this example is artificial, but when used well, this separation of classes and persistent instances can eliminate many traditional database update programs -- in most cases, you can simply change the class, not each stored instance, for new behavior. 16.5.5 Shelve ConstraintsAlthough shelves are generally straightforward to use, there are a few rough edges worth knowing about. <IP_ADDRESS> Keys must be stringsFirst of all, although they can store arbitrary objects, keys must still be strings. The following fails, unless you convert the integer 42 to string "42" manually first: dbase[42] = value # fails, but str(42) will work This is different from in-memory dictionaries, which allow any immutable object to be used as a key, and derives from the shelve's use of DBM files internally. <IP_ADDRESS> Objects are only unique within a keyAlthough the shelve module is smart enough to detect multiple occurrences of a nested object and recreate only one copy when fetched, this only holds true within a given slot: dbase[key] = [object, object] # okay: only one copy stored and fetched dbase[key1] = object dbase[key2] = object # bad?: two copies of object in the shelve When key1 and key2 are fetched, they reference independent copies of the original shared object; if that object is mutable, changes from one won't be reflected in the other. This really stems from the fact the each key assignment runs an independent pickle operation -- the pickler detects repeated objects but only within each pickle call. This may or may not be a concern in your practice and can be avoided with extra support logic, but an object can be duplicated if it spans keys. <IP_ADDRESS> Updates must treat shelves as fetch-modify-store mappingsBecause objects fetched from a shelve don't know that they came from a shelve, operations that change components of a fetched object only change the in-memory copy, not the data on a shelve: dbase[key].attr = value # shelve unchanged To really change an object stored on a shelve, fetch it into memory, change its parts, and then write it back to the shelve as a whole by key assignment: object = dbase[key] # fetch it object.attr = value # modify it dbase[key] = object # store back-shelve changed <IP_ADDRESS> Concurrent updates not allowedAs we learned near the end of Chapter 14, the shelve module does not currently support simultaneous updates. Simultaneous readers are okay, but writers must be given exclusive access to the shelve. You can trash a shelve if multiple processes write to it at the same time, and this is a common potential in things like CGI server-side scripts. If your shelves may be hit by multiple processes, be sure to wrap updates in calls to the fcntl.flock built-in we explored in Chapter 14. <IP_ADDRESS> Pickler class constraintsIn addition to these shelve constraints, storing class instances in a shelve adds a set of additional rules you need to be aware of. Really, these are imposed by the pickle module, not shelve, so be sure to follow these if you store class objects with pickle directly, too.
In a prior Python release, persistent object classes also had to either use constructors with no arguments, or they had to provide defaults for all constructor arguments (much like the notion of a C++ copy constructor). This constraint was dropped as of Python 1.5.2 -- classes with non-defaulted constructor arguments now work fine in the pickling system.[2]
<IP_ADDRESS> Other persistence limitationsIn addition to the above constraints, keep in mind that files created by an underlying DBM system are not necessarily compatible with all possible DBM implementations. For instance, a file generated by gdbm may not be readable by a Python with another DBM module installed, unless you explicitly import gdbm instead of anydbm (assuming it's installed at all). If DBM file portability is a concern, make sure that all the Pythons that will read your data use compatible DBM modules. Finally, although shelves store objects persistently, they are not really object-oriented database systems (OODBs). Such systems also implement features like object decomposition and delayed ("lazy") component fetches, based on generated object IDs: parts of larger objects are loaded into memory only as they are accessed. It's possible to extend shelves to support such features, but you don't need to -- the Zope system described in Chapter 15, includes an implementation of a more complete OODB system. It is constructed on top of Python's built-in persistence support, but offers additional features for advanced data stores. See the previous chapter for information and links. |

I need to change the HDD of my Linksys NSLU2 so I will use the opportunity to write a small HowTo to show how to set up an unslung firmware into my nslu2. Let’s start
First of all I need to download the last version of Unslung firmware and install in my ubuntu box the software to put the firmware into my nslu2:
sudo aptitude install upslug2
I put my nslu2 into upgrade mode and …
# upslug2
[no NSLU2 machines found in upgrade mode]
What happen? I always forget I have two network cards (eth0 and eth1) and I use eth1
upslug2 -help
upslug2: usage: upslug2 {options}
options:
[extract]
-d --device[eth0]: local ethernet device to use
-t --target: NSLU2 to upgrade (MAC address)
-i --image: complete flash image to use
so …
sudo upslug2 -d eth1 -t 00:13:10:d9:03:ff -i Unslung-6.10-beta.bin
network is a my home network is a <IP_ADDRESS>/24 so I need to change my IP if I want to connect to my nslu2:
sudo ifconfig eth1 <IP_ADDRESS> netmask <IP_ADDRESS> up
Now I open a browser and type http://<IP_ADDRESS>/
From the web interface I change the ip from <IP_ADDRESS> to <IP_ADDRESS>, the gateway and the dns.
change again my IP
sudo ifconfig eth1 <IP_ADDRESS> netmask <IP_ADDRESS> up
and open again a browser http://<IP_ADDRESS>/
Now I format plug the HDD to the device (into Disk1) and format it from the web inteface.
Now I enable telnet, telnet to the device with the default username/password (root/uNSLUng) and unsling disk1
telnet <IP_ADDRESS>
Trying <IP_ADDRESS>...
Connected to <IP_ADDRESS>.
Escape character is '^]'.
