# NPM (Node Package Manager) It is the default package manager for Node.js and is written entirely in Javascript. Developed by **Isaac Z. Schlueter**, it was initially released in January 12, 2010. NPM manages all the packages and modules for Node.js and consists of command line client npm. It gets installed into the system with installation of Node.js. The required packages and modules in Node project are installed using NPM. --- ## NPM A package contains all the files needed for a module and modules are the JavaScript libraries that can be included in Node project according to the requirement of the project. --- ## NPM NPM can install all the dependencies of a project through the `package.json` file. It can also update and uninstall packages. In the `package.json` file, each dependency can specify a range of valid versions using the semantic versioning scheme, allowing developers to auto-update their packages while at the same time avoiding unwanted breaking changes. --- ### Some facts about NPM: - At this moment, NPM has 580096 registered packages. The average rate of growth of this number is 291/day which outraces every other package registry. - npm is open source - The top npm packages in the decreasing order are: lodash, async, react, request, express. --- # The End


Cred is a pluggable authentication system for servers. It allows any
number of network protocols to connect and authenticate to a system, and
communicate to those aspects of the system which are meaningful to the specific
protocol. For example, Twisted's POP3 support passes a username and
password
set of credentials to get back a mailbox for the specified email
account. IMAP does the same, but retrieves a slightly different view of the
same mailbox, enabling those features specific to IMAP which are not available
in other mail protocols.
Cred is designed to allow both the backend implementation of the business logic - called the avatar - and the authentication database - called the credential checker - to be decided during deployment. For example, the same POP3 server should be able to authenticate against the local UNIX password database or an LDAP server without having to know anything about how or where mail is stored.
To sketch out how this works - a Realm
corresponds to an application
domain and is in charge of avatars, which are network-accessible business logic
objects. To connect this to an authentication database, a top-level object
called a Portal
stores a
realm, and a number of credential checkers. Something that wishes to log in,
such as a Protocol
,
stores a reference to the portal. Login consists of passing credentials and a
request interface (e.g. POP3's IMailbox
) to the portal. The portal passes
the credentials to the appropriate credential checker, which returns an avatar
ID. The ID is passed to the realm, which returns the appropriate avatar. For a
Portal that has a realm that creates mailbox objects and a credential checker
that checks /etc/passwd, login consists of passing in a username/password and
the IMailbox interface to the portal. The portal passes this to the /etc/passwd
credential checker, gets back a avatar ID corresponding to an email account,
passes that to the realm and gets back a mailbox object for that email
account.
Putting all this together, here's how a login request will typically be processed:
This is the the core of login, the point of integration between all the objects
in the cred system. There is one
concrete implementation of Portal, and no interface - it does a very
simple task. A Portal
associates one (1) Realm with a collection of
CredentialChecker instances. (More on those later.)
If you are writing a protocol that needs to authenticate against something, you will need a reference to a Portal, and to nothing else. This has only 2 methods -
login
(credentials, mind, *interfaces)
The docstring is quite expansive (see twisted.cred.portal
), but in
brief, this is what you call when you need to call in order to connect
a user to the system. Typically you only pass in one interface, and the mind
is None
. The interfaces are the possible interfaces the returned
avatar is expected to implement, in order of preference.
The result is a deferred which fires a tuple of:
*interfaces
tuple)The logout method has to be called when the avatar is logged out. For POP3 this means when the protocol is disconnected or logged out, etc..
registerChecker
(checker, *credentialInterfaces)
which adds a CredentialChecker to the portal. The optional list of interfaces are interfaces of credentials that the checker is able to check.
This is an object implementing ICredentialsChecker
which resolves some
credentials to an avatar ID.
Whether the credentials are stored in an in-memory data structure, an
Apache-style htaccess file, a UNIX password database, an SSH key database,
or any other form, an implementation of ICredentialsChecker
is
how this data is connected to cred.
A credential checker
stipulates some requirements of the credentials it can check by
specifying a credentialInterfaces attribute, which is a list of
interfaces. Credentials passed to its requestAvatarId method must
implement one of those interfaces.
For the most part, these things will just check usernames and passwords and produce the username as the result, but hopefully we will be seeing some public-key, challenge-response, and certificate based credential checker mechanisms soon.
A credential checker should raise an error if it cannot authenticate
the user, and return twisted.cred.checkers.ANONYMOUS
for anonymous access.
Oddly enough, this represents some credentials that the user presents. Usually this will just be a small static blob of data, but in some cases it will actually be an object connected to a network protocol. For example, a username/password pair is static, but a challenge/response server is an active state-machine that will require several method calls in order to determine a result.
Twisted comes with a number of credentials interfaces and implementations
in the twisted.cred.credentials
module,
such as IUsernamePassword
and IUsernameHashedPassword
.
A realm is an interface which connects your universe of business
objects
to the authentication system.
IRealm
is another one-method interface:
requestAvatar
(avatarId, mind, *interfaces)
This method will typically be called from 'Portal.login'. The avatarId is the one returned by a CredentialChecker.
avatarId
must always be a string. In
particular, do not use unicode strings. If internationalized support is needed,
it is recommended to use UTF-8, and take care of decoding in the realm. The important thing to realize about this method is that if it is being called, the user has already authenticated. Therefore, if possible, the Realm should create a new user if one does not already exist whenever possible. Of course, sometimes this will be impossible without more information, and that is the case that the interfaces argument is for.
Since requestAvatar should be called from a Deferred callback, it may return a Deferred or a synchronous result.
An avatar is a business logic object for a specific user. For POP3, it's
a mailbox, for a first-person-shooter it's the object that interacts with
the game, the actor as it were. Avatars are specific to an application,
and each avatar represents a single user
.
As mentioned before, the mind is usually None
, so you can skip this
bit if you want.
Masters of Perspective Broker already know this object as the ill-named
client object
. There is no mind
class, or even interface, but it
is an object which serves an important role - any notifications which are to be
relayed to an authenticated client are passed through a 'mind'. In addition, it
allows passing more information to the realm during login in addition to the
avatar ID.
The name may seem rather unusual, but considering that a Mind is
representative of the entity on the other end
of a network connection
that is both receiving updates and issuing commands, I believe it is
appropriate.
Although many protocols will not use this, it serves an important role. It is provided as an argument both to the Portal and to the Realm, although a CredentialChecker should interact with a client program exclusively through a Credentials instance.
Unlike the original Perspective Broker client object
, a Mind's
implementation is most often dictated by the protocol that is
connecting rather than the Realm. A Realm which requires a particular
interface to issue notifications will need to wrap the Protocol's mind
implementation with an adapter in order to get one that conforms to its
expected interface - however, Perspective Broker will likely continue
to use the model where the client object has a pre-specified remote
interface.
(If you don't quite understand this, it's fine. It's hard to explain, and it's not used in simple usages of cred, so feel free to pass None until you find yourself requiring something like this.)
The protocol implementor should define the interface the avatar should implement, and design the protocol to have a portal attached. When a user logs in using the protocol, a credential object is created, passed to the portal, and an avatar with the appropriate interface is requested. When the user logs out or the protocol is disconnected, the avatar should be logged out.
The protocol designer should not hardcode how users are authenticated or the realm implemented. For example, a POP3 protocol implementation would require a portal whose realm returns avatars implementing IMailbox and whose credential checker accepts username/password credentials, but that is all. Here's a sketch of how the code might look - note that USER and PASS are the protocol commands used to login, and the DELE command can only be used after you are logged in:
from zope.interface import Interface from twisted.protocols import basic from twisted.python import log from twisted.cred import credentials, error from twisted.internet import defer class IMailbox(Interface): """Interface specification for mailbox.""" def deleteMessage(index): pass class POP3(basic.LineReceiver): # ... def __init__(self, portal): self.portal = portal def do_DELE(self, i): # uses self.mbox, which is set after login i = int(i)-1 self.mbox.deleteMessage(i) self.successResponse() def do_USER(self, user): self._userIs = user self.successResponse('USER accepted, send PASS') def do_PASS(self, password): if self._userIs is None: self.failResponse("USER required before PASS") return user = self._userIs self._userIs = None d = defer.maybeDeferred(self.authenticateUserPASS, user, password) d.addCallback(self._cbMailbox, user) def authenticateUserPASS(self, user, password): if self.portal is not None: return self.portal.login( cred.credentials.UsernamePassword(user, password), None, IMailbox ) raise error.UnauthorizedLogin() def _cbMailbox(self, ial, user): interface, avatar, logout = ial if interface is not IMailbox: self.failResponse('Authentication failed') log.err("_cbMailbox() called with an interface other than IMailbox") return self.mbox = avatar self._onLogout = logout self.successResponse('Authentication succeeded') log.msg("Authenticated login for " + user)
The application developer can implement realms and credential checkers. For example, she might implement a realm that returns IMailbox implementing avatars, using MySQL for storage, or perhaps a credential checker that uses LDAP for authentication. In the following example, the Realm for a simple remote object service (using Twisted's Perspective Broker protocol) is implemented:
from twisted.spread import pb from twisted.cred.portal import IRealm class SimplePerspective(pb.Avatar): def perspective_echo(self, text): print 'echoing',text return text def logout(self): print self, "logged out" class SimpleRealm: implements(IRealm) def requestAvatar(self, avatarId, mind, *interfaces): if pb.IPerspective in interfaces: avatar = SimplePerspective() return pb.IPerspective, avatar, avatar.logout else: raise NotImplementedError("no interface")
Deployment involves tying together a protocol, an appropriate realm and a credential checker. For example, a POP3 server can be constructed by attaching to it a portal that wraps the MySQL-based realm and an /etc/passwd credential checker, or perhaps the LDAP credential checker if that is more useful. The following example shows how the SimpleRealm in the previous example is deployed using an in-memory credential checker:
from twisted.spread import pb from twisted.internet import reactor from twisted.cred.portal import Portal from twisted.cred.checkers import InMemoryUsernamePasswordDatabaseDontUse portal = Portal(SimpleRealm()) checker = InMemoryUsernamePasswordDatabaseDontUse() checker.addUser("guest", "password") portal.registerChecker(checker) reactor.listenTCP(9986, pb.PBServerFactory(portal)) reactor.run()
Cred offers a plugin architecture for authentication methods. The primary API for this architecture is the command-line; the plugins are meant to be specified by the end-user when deploying a TAP (twistd plugin).
For more information on writing a twistd plugin and using cred plugins for your application, please refer to the Writing a twistd plugin document.
To build a plugin for cred, you should first define an authType
, a short one-word string that defines
your plugin to the command-line. Once you have this, the convention is
to create a file named myapp_plugins.py
in the
twisted.plugins
module path.
Below is an example file structure for an application that defines such a plugin:
Once you have created this structure within your application, you can
create the code for your cred plugin by building a factory class which
implements ICheckerFactory
.
These factory classes should not consist of a tremendous amount of
code. Most of the real application logic should reside in the cred
checker itself. (For help on building those, scroll up.)
The core purpose of the CheckerFactory is to translate an argstring
, which is passed on the command line,
into a suitable set of initialization parameters for a Checker
class. In most cases this should be little more than constructing a
dictionary or a tuple of arguments, then passing them along to a new
checker instance.
from zope.interface import implements from twisted import plugin from twisted.cred import checkers from myapp.cred import SpecialChecker class SpecialCheckerFactory(object): """ A checker factory for a specialized (fictional) API. """ # The class needs to implement both of these interfaces # for the plugin system to find our factory. implements(checkers.ICheckerFactory, plugin.IPlugin) # This tells AuthOptionsMixin how to find this factory. authType = "special" # This is a one-line explanation of what arguments, if any, # your particular cred plugin requires at the command-line. argStringFormat = "A colon-separated key=value list." # This help text can be multiple lines. It will be displayed # when someone uses the "--help-auth-type special" command. authHelp = """Some help text goes here ...""" # This will be called once per command-line. def generateChecker(self, argstring=""): argdict = dict((x.split('=') for x in argstring.split(':'))) return SpecialChecker(**dict) # We need to instantiate our class for the plugin to work. theSpecialCheckerFactory = SpecialCheckerFactory()
For more information on how your plugin can be used in your application (and by other application developers), please see the Writing a twistd plugin document.

For the Windows Folks
We have tthree tutorials selected here. The first is a quick run down of the entire movie making process on a PC. The second two take a more indepth look at Serif Movie Plus, one of the software options featured in the first video.
Just an FYI, Serif Movie PLus has a free and a super pricey version, so make sure you search for 'Free Serif Movie Plus'. It's a really powerful Windows-only tool.
From Start to Finish on a PC
Here's a short video teaching you how to make your super short video. This quick tutorial takes you from begining to uploading your video on youTube. It highlights the basic functionality of Windows Live Movie Maker, then moves on to more advanced functionality with Serif Movie Plus, and finally uploading the video to YouTube. It also makes use of free screen capture software like Tiny Take, which can really come in handy when making informative videos.
Serif Movie Plus Starter Edition
This first tutorial covers cropping. This is one of the best features that Serif Movie Plus has to offer, especially for newbies in the film making world. New film makers often film from too wide an angle, losing the drama and detail of a full frame. Check out the tutorial below to get a very detailed tutorial on using this powerful tool.
This second tutorial shows you how to use a tool strongly featured in the overview video, putting a still image or second vieo inside your video. Depending on the style of your film, this may or may not be useful for you. Even if you don't plan on embedding a video in your video, check out the tutorial because it can help with overlaying audio too.

module Enumerable(T)
Overview
The Enumerable
mixin provides collection classes with several traversal, searching,
filtering and querying methods.
Including types must provide an each
method, which yields successive members
of the collection.
For example:
class Three
include Enumerable(Int32)
def each
yield 1
yield 2
yield 3
end
end
three = Three.new
three.to_a # => [1, 2, 3]
three.select &.odd? # => [1, 3]
three.all? { |x| x < 10 } # => true
Note that most search and filter methods traverse an Enumerable eagerly,
producing an Array
as the result. For a lazy alternative refer to
the Iterator
and Iterable
modules.

RAKE — Ruby Make
This package contains Rake, a simple ruby build program with capabilities similar to make.
Rake has the following features:
- Rakefiles (rake’s version of Makefiles) are completely defined in standard Ruby syntax. No XML files to edit. No quirky Makefile syntax to worry about (is that a tab or a space?)
- Users can specify tasks with prerequisites.
- Rake supports rule patterns to synthesize implicit tasks.
- Flexible FileLists that act like arrays but know about manipulating file names and paths.
- A library of prepackaged tasks to make building rakefiles easier. For example, tasks for building tarballs and publishing to FTP or SSH sites. (Formerly tasks for building RDoc and Gems were included in rake but they’re now available in RDoc and RubyGems respectively.)
- Supports parallel execution of tasks.
Installation
Gem Installation
Download and install rake with the following.
gem install rake
Normal Installation
You can download the source tarball of the latest version of Rake from
Extract the tarball and run
% ruby install.rb
from its distribution directory.
Usage
Simple Example
First, you must write a “Rakefile” file which contains the build rules. Here’s a simple example:
task :default => [:test] task :test do ruby "test/unittest.rb" end
This Rakefile has two tasks:
- A task named “test”, which - upon invocation - will run a unit test file in Ruby.
- A task named “default”. This task does nothing by itself, but it has exactly one dependency, namely the “test” task. Invoking the “default” task will cause Rake to invoke the “test” task as well.
Running the “rake” command without any options will cause it to run the “default” task in the Rakefile:
% ls Rakefile test/ % rake (in /home/some_user/Projects/rake) ruby test/unittest.rb ....unit test output here...
Type “rake —help” for all available options.
More Information
- For details on Rake’s command-line invocation, read doc/command_line_usage.rdoc
- For details on writing Rakefiles, see doc/rakefile.rdoc.
- For the original announcement of Rake, see doc/rational.rdoc.
- For a glossary of terms, see doc/glossary.rdoc.
Development
Source Repository
Rake is currently hosted at github. The github web page is github.com/jimweirich/rake. The public git clone URL is
- git://github.com/jimweirich/rake.git
Running the Rake Test Suite
If you wish to run the unit and functional tests that come with Rake:

Virtualization is the process of running a virtual instance of a computer system in a layer abstracted from the actual hardware. Most commonly, it refers to running multiple operating systems on a computer system simultaneously. To the applications running on top of the virtualized machine, it can appear as if they are on their own dedicated machine, where the operating system, libraries, and other programs are unique to the guest virtualized system and unconnected to the host operating system which sits below it.
There are many reasons why people utilize virtualization in computing.
Virtualization management software is designed to—well—make virtualization more manageable. Sure, you can manually allocate resources into VMs, make space for them on servers, test them, and install patches as needed. But splitting single systems into hundreds means multiplying the work needed to keep those systems running, up to date, and secure. If all the VMs are tied to a monitoring, provisioning, or management tool, systems can be migrated automatically to better-suited hardware during periods of peak use or maintenance. Imagine a farm of servers that can be retasked in seconds—according to workload and time of day. As a particular guest instance begins consuming more resources, the monitoring system moves that guest to another server with less demand or or allocates more resources to it from a central pool.

MerMEId basics
MerMEId (Metadata Editor and Repository for MEI data) is a tool for editing, (pre-)viewing and handling of music metadata based on MEI.
The user interface has three main components: the MEI file browser, the metadata editing tool, and the HTML preview.
Document list
The usual way to start working with MerMEId would be to open the document list, usually located at http://[your hostname here]/modules/list_files.xq. You should then see a list of existing documents in your collection (if any):
Creating a new document: To create a new document, click the add button located in the upper right corner. This will open a new document in the metadata editor.
Listing existing documents: Near the top of the documents list page, a number of controls allow you to you choose which documents to list. A select box lets you filter documents by collection, provided you have specified file collection information in your files. You may also narrow the results using the keywords search.
Navigate through the result pages using the page numbers or the 'Previous page' / 'Next page' links.
From the list, you have the following options:
- HTML preview: Click the title of any file to see its metadata displayed as formatted HTML.
- XML source: Click the XML view icon to see the document's plain XML data
- Edit file: Click the edit icon to open the document in the metadata editor
- Copy file: Click the copy icon to make a copy of the document. The copied resource will have '(copy)' added to its title to distinguish it from the original.
- Rename file: Click the rename icon
to rename a document.
Please note that MerMEId does not update any references in other documents pointing to the renamed one; in other words, links between documents are likely to be broken when renaming resources. - Delete file: Clicking the delete icon will display a warning that you are about to delete the selected document. Click 'OK' to delete, otherwise 'Cancel'.
The editor – general functionality and navigation
The editor (i.e. the forms for editing your data) is divided into a number of separate forms. You navigate through the main parts of it by clicking the tabs at the top of the page:
- Make sure to save any changes you have made before switching tabs. A warning occurs if you are about to change tab without having saved changes.
Some general functions are found in the upper right corner of the form:
| Save file | |
| HTML preview | |
| XML source view | |
| Close the editor end return to document list | |
| Settings | |
| Open this manual |
Next to repeatable fields you will find a number of icons for adding, deleting and re-arranging items:
| Move up (change order of items) | |
| Move down | |
| Duplicate item (adds a copy of the current item) | |
| Add new item below the current one | |
| Delete | |
| Shift this item to the right, making it a sub-component (child) of the item above (applies to music components only) | |
| Shift this item to the left, i.e. up one level (applies to music components only) | |
| Edit this item (opens a details editor) | |
| Go to a linked resource (implies closing the current file and opening a different one for editing) | |
| Add reference to an authority file (applies to personal names) |
Hints: Next to many input fields you will find a question mark ?Hint or explanation. Hovering over the question mark displays a hint, an explanation or other useful information.
HTML Preview
The purpose of the HTML preview is to give you an overview of the (meta-)data you have entered. Your project may or may not use it as a basis for public display of your data as well, but probably this is not how your data will be displayed in the end.
If titles or other texts are given in more than one language, all other alternatives than the first one are shown in grey. To hide these alternative language texts, click the "Hide alternative languages" link in the upper right corner.
By default, only the headings of the main sections are shown. To view the contents, click the the expand icon or the heading. To hide the contents, click the heading again. The number of headings shown depends on which sections have any content.
At the bottom of the page, in grey, metadata about the file are displayed (i.e. the colophon).

Chromebook drop test crowns Google Pixelbook as most durable, ‘an absolute tank’
by Ben SchoonA lot of Chromebooks out on the market today are rated to take a beating, but dropping any laptop is still a scary thought. In a recent Chromebook drop test, it was actually Google’s premium Pixelbook that came out on top.
LaptopMag sought out to find the toughest Chromebook on the market today with a drop test. The outlet took 11 different models that are currently available for purchase including the Pixelbook, Asus C434, Lenovo C330, and many others.
The test saw these machines pushed off of a table from 2.5 feet onto carpet and concrete while closed. Then, to simulate falling out of a backpack, they were dropped from 4.5 feet in the same conditions. Finally, the surviving machines were dropped from 4.5 feet while opened onto concrete.
The only machine that survived every single one of these tests was Google’s Pixelbook. The only damage to the machine was a small nick on the corner and “barely a scratch” when it was dropped for the final time. LaptopMag calls it an “absolute tank.”
What about the rest of the collection? The Samsung Chromebook 3 held up well with only some very minor damage. The Lenovo Chromebook 300e, Dell Chromebook 11 3180, Asus C202SA, and HP Chromebook 11 all suffered some cracks in the plastic but mostly held up well. Things start going downhill from that point, though.
The Acer Chromebook 11 N7 held up well while the laptop was closed, but once dropped while open it broke the hinges. The Samsung Chromebook Plus also suffered from quite a bit of damage when dropped which extended to the trackpad. The machine was still function, but even the display showed signs of damage. The Acer Chromebook R13 also suffered major damage with the display separating from the housing completely.
Some of the carnage caused by this Chromebook drop test
Lenovo’s super popular Chromebook C330 didn’t fair too well either. The display detached and a large portion of the bottom corner completely broke off too. Asus’ C434 faired worst of all, though. The metal frame quickly bent and the screen shattered by the final drop. After a bit of testing, the machine died entirely.

I'm A Celebrity: Roman Kemp and Adele Roberts' spat over Jane McDonald
Viewers were on Roman's side
by Karen HylandRoman Kemp and Adele Roberts got into an argument over Jane McDonald during I’m A Celebrity… Get Me Out of Here! and now they are both up for the next Bushtucker Trial.
The two radio DJs were seen bickering over Loose Women star Jane McDonald, after Adele brought a photo of her into the jungle as her luxury item.
Adele was one of only two campmates to successfully retrieve their luxury item on Monday, and the picture was hung up in the camp for all to see, much to the confusion of her fellow celebrities, including Roman.
Kate Garraway kicked off the conversation when she asked: "Jane McDonald is looking over us, can you think of a song of hers?"
And Radio 1 DJ Adele confessed: "I know her off Loose Women, I don’t know her actual songs but I know her from the cruising show when she does covers.
"She’ll cruise around the world, for example she’d go to Iceland and then sing a Bjork or would go to the USA and sing Proud Mary."
But the 40-year-old presenter became upset when Roman and Rak-Su singer Myles Stephenson began to laugh, and claimed "no-one knows" who Jane is.
Roman said: "It’s just random mate."
Adele hit back: "Why though? I don’t understand. If I had brought in a picture of Ru-Paul would you have the same reaction?
"That’s prejudice, I’m allowed to like what I want. It’s like you’re saying 'why would I like Jane McDonald?'"
When Roman, 26, realised he’d upset Adele he began to apologise, but insisted the situation was "funny".
He said: "Adele it’s not, the situation is funny. I wasn’t saying that at all, I’m sorry, I didn’t mean to."
The Capital FM DJ apologised again, and gave Adele a hug as he said he was fond of the picture.
He told her: "I like the picture being there."
Viewers quickly picked a corner, defending Roman over the strange spat.
Tomorrow night the pair will take on the Bushtucker Trial...
Elsewhere in the episode, all five of the Snake Rock campmates - Caitlyn Jenner, James Haskell, Ian Wright, Jacqueline Jossa, and Andrew Maxwell - faced the Bush Tucker Trial, in which they won seven out of a possible 10 stars, and therefore bagged seven meals for camp.
After the trial, they were allowed to enter the main camp, marking the first time this series that all 10 campmates have been based in the same camp.

Writing and Using RISC-V user mode exception handlers in RARS
Introduction
Interrupts are a way to break away from the current execution path and deal with a potentially time sensitive
issue and then return to the previous execution path. Interrupts fall into three categories: software, timer, and external.
Software interrupts are triggered by setting a bit in the interrupt pending CSR. Timer interrupts are triggered by a timer.
External interrupts come from outside the CPU. Both timer and external interrupts can be caused from tools from the tools menu.
Synchronous traps are caused by code not being able to continue on its current path without having additional actiion taken.
This can be because the code is incorrect (e.g. load access misaligned) or because action needs to be taken by the OS
(ecall, ebreak, page fault, etc).
Exception handlers allow programs to handle both of these cases. Every trap must be handled immediately either by the
program, or by RARS. System calls and breakpoints are normally handled by RARS, but other faults are generally handled
by printing an error message to the console. The program's exception handler doesn't have to print to console though.
Below is a simple handler which just skips over instructions generating traps:
.text
main:
la t0,handler
csrrw zero, 5, t0 # set utvec (5) to the handlers address
csrrsi zero, 0, 1 # set interrupt enable bit in ustatus (0)
lw zero, 0 # trigger trap for Load access fault

uret
In order to have a working exception handler, the program must:
- Set utvec to the address of the handler code (the lowest two bits are special)
- Set the bits corresponding to the handled interrupts in uie
- Set the interrupt enable (lowest) bit in ustatus to enable the handler
And inside the handler, :
- The exception handler can return control to the program using
the uret instruction. This will place the uepc CSR value into the
Program Counter, so be sure to increment it by 4 before returning if you want
to skip over the instruction that caused the exception. It also resets some other
state to before the exception, so jumping to the value in uepc instead is not recommended
- ucause contains the reason that the exception handler was called.
- Exception types declared in rars.SimulatorException, but
not necessarily implemented, are INSTRUCTION_ADDR_MISALIGNED (0),
INSTRUCTION_ACCESS_FAULT (1), ILLEGAL_INSTRUCTION(2),
LOAD_ADDRESS_MISALIGNED(4), LOAD_ACCESS_FAULT(5),
STORE_ADDRESS_MISALIGNED(6), STORE_ACCESS_FAULT(7), and ENVIRONMENT_CALL(8)
- When writing a non-trivial exception handler, your handler must first save
general purpose register contents, then restore them before returning.
The implementation of user-mode exception handlers in RARS is not complete and does not fully conform to the RISC-V
privilidged specification, but it is based upon that and contributions to make it be more conformant would be appreciated.
For more details, refer to the RISC-V priviledged specification https://riscv.org/specifications/privileged-isa/;
contributions to pull in more details into this page would be appreciated.


Metro Trains Melbourne needed a tool for monitoring real time voltages and currents for testing their new trains.
This work combined hardware installed in the field (created by my co-worker) and a server with a front end (created by me).
The hardware was made up of an industrial PC with a USB oscilloscope and 4G modem.
I worked on:
Rome2rio is a travel search website used for finding and comparing different routes from anywhere in the world. It specialised in ground transport.

After 3 years the Melbourne office split off to form the company migenius which continued to do the same work
and allowed for working on stand alone products.
Bloom Unit was their first product and combined the ease of using SketchUp's 3d editing with real time
photographic images.
I worked on:
We also worked on other projects for various clients:

Paper-, er, Transcript-Folding Game
问题描述 :
Most recently, frkstyc has engaged himself busily in applying for admission to graduate schools abroad. Among all those tasks he has to complete, one is to prepare the transcripts to mail to the admission offices. Earlier, frkstyc ordered his transcripts from the university’s Educational Admnistration Division (EAD). As per the regulations of the EAD, upon claiming the transcripts in the EAD office, he had to fold the transcripts until they fit into the envelops provided by the EAD, which were later sealed and stamped at the scene. Having unwisely overestimated the actual number of transcripts required, he ordered twice as many transcripts as needed, which left him with a very uninteresting and fatiguing paper-folding game. Finishing the work, he swore to himself that never again would he trouble himself with applications for admission aboard.
To help you better understand frkstyc’s experience folding his transcripts, consider this problem: given the dimensions of an envelop and a transcript, how many times does the transcript have to be folded until its dimensions do not exceed those of the envelop? Remember that frkstyc was preparing the transcripts for the review of faculty members in admission commitees, which required him to fold the transcripts either horizontally or vertically each time, halving its size. Additionally, the transcript must not lie slanted in the envelop.
输入:
The input contains multiple test cases each occupying one line. Each test case consists of four integers a, b, c, d (0 < a, b, c, d ≤ 231 − 1) indicating that the dimension of an envelop is a × b and that of a transcript is c × d. Process until EOF is met.
输出:
For each test case, output the minimum number of times a transcript has to be folded.
样例输入:
1 2 1 4 2 1 1 4
样例输出:
1 1
解题代码:
//* @author: Yeming<EMAIL_ADDRESS>import java.util.*; public class Main { public static void main(String[] args) { Scanner sc = new Scanner(System.in); while(sc.hasNext()) { long a = sc.nextLong(); long b = sc.nextLong(); double c = sc.nextDouble(); double d = sc.nextDouble(); int steps = 0; if(a > b) { long temp = a; a = b; b = temp; } while(true) { if(c > d) { double temp = c; c = d; d = temp; } if(a >= c && b >=d) { break; }else if(b < d) { d = d/2; steps++; }else { c = c/2; steps++; } } System.out.println(steps); } } }

多谢支持！
helpful！！ mark
为什么暴力求解方法循环到sqrt(n) 就可以了呢
第二种解法如果数组有重复元素 就不正确
不太明白DFS的方法
对，还是这种实现比较好理解。虽然效率有点低
学习了
多谢支持！
int L[m+1][n+1];这样定义出错，这个在gcc上可以编译通过 在VS上不行 应该改为new 或者vector
很好的题，还是能做出几道的，嘿嘿
第二个方法挺不错。NewHead代表新的头节点，通过递归找到最后一个节点之后，就把这个节点赋给NewHead，然后一直返回返回，中途这个值是没有变化的，一边返回一边把相应的指针方向颠倒，最后结束时返回新的头节点到主函数。
很好的题，还是能做出几道的，嘿嘿
第一段代码中：
next = next ;
明显不对吧，应该是 next =j;才对
很好，解决了


Rocky Balboa aka Sylvester Stallone
Hello this is Dominic Wong:) I am a UC Berkeley graduate majored in Economics and minored in Computer Sceience. I started coding in Fall 2017. Before that, I have never thought of learning computer or coding related things as I have never been exposed to this kind of knowledge. However, I took my first CS class in my life, CS61A (Structure and Interpretation of Computer Programs aka Python, SQL and Scheme?!) in Berkeley becuase of my friends' recommendation. I felt so hard to pick up at first due to the huge difference of conceptual thinking. However, I found out CS could be really interesting because you keep solving problems and making new stuff. I further self-learn web development by myself after chatting with another friend. I have been really into web developing because I can actually make my own website and design it in any way I want. Hope that your enjoy my webpages:)
Below are three photos I want to want to share with you :)
The first time I went to NYC. At Top of the Rock and the building with blue light was the Empire State Building.
My parents and I when I graduated from college. They were definitely more excited than I was lmao
