TouchDB was recently renamed to Couchbase Lite, and here are the differences:
Other than that, at this point there's not actually that much difference in the codebases. However the codebases are expected to diverge.
It's currently unclear what will happen to TouchDB in terms of maintenance, at the moment there is no known "corporate sponsor" or active community behind it.
Android 2.3 Gingerbread (API level 9) and above.
Android Studio is the current recommended IDE, however if you are required to use Eclipse, here is some information that discusses the current situation with Eclipse compatibility.
Since Eclipse + Maven plugin cannot handle .aar dependencies, and the Couchbase-Lite libraries are packaged as .aar's, there is no way to currently use the Maven dependencies.
The two alternatives for including dependencies are:
NOTE: It may be possible to export projects to Eclipse via the Gradle Eclipse plugin, which can create correct Eclipse projects just by adding apply plugin: 'eclipse'
in each project's build.gradle file, and then from the root just run "gradle eclipse" and it will create the project files ready to import.
See Building In Eclipse in the Android Bootstrap README, which might have relevant information.
They are not in Maven Central yet, but we are planning to upload them into Maven Central at some point.
A: Couchbase Lite is designed to be modular, allowing the application developer to choose the pieces they need and distribute the smallest application possible.
A: The CBLiteEktorp uses a forked version of Ektorp based on Ektorp 1.2.2.
A: Create the couchDbConnector once in the application, and have the different activities reference it via:
couchDbConnector = ((MyApplication)getApplication()). couchDbConnector;
UnrecognizedPropertyException: Unrecognized field .., not marked as ignorable
A: The Jackson JSON parser supports an annotation @JsonIgnoreProperties(ignoreUnknown=true)
which will allow older coder to parse and ignore unknown fields in the JSON.
The method ... of type ... must override or implement a supertype method
A: Typically this happens when you're not using a 1.6 compiler. Check your Java Compiler settings in Eclipse and choose a 1.6 compiler.
A: The CBLDatabase object implements Observable, so if you add an Observer you will get notifications in the form of a Map changeNotification, which will have {"rev": $revIdOfNewlyAddedRevision, "seq": $seqNumberOfNewlyAddedRevision, "source": $urlOfReplicationIfApplicable}
A: It is running on a different network interface, so to connect to the "host" which launched the emulator, you must use the special ip address: <IP_ADDRESS>.
A: The HttpClient used by Couchbase Lite has some pluggability support for the SSL certificate trust. See this pull request for an example on how to do this.
[2012-05-15 15:27:32 - Couchbase-Lite-Android] Could not find Couchbase-Lite-Android.apk!
A: Remove the preset "Is Libary" from the projects (Projects->Properties->Android->Library) and run each of them (Run As->Android Application). Eclipse might prompt an error message saying there was not found an "Launcher activity" but it has synced the android application package. Do not forget to set the library as "Is Library" afterwards again or you will get another error message when using the packages for example with the TestApp.
java.lang.NoSuchMethodError: android.database.sqlite.SQLiteDatabase.insertWithOnConflict
A: This happens when you run with an SDK < 2.2. Couchbase-Lite-Android requires SDK 2.2 or newer.
java.net.MalformedURLException: Unknown protocol: cblite
A: When using the Ektorp adapter we need to install a URL handler for the cblite
protocol. This needs to be done early in your application life-cycle prior to using Couchbase Lite or accessing any other URLs. Currently I recommend you place the following static initialization block in your application's main Activity:
{
CBLURLStreamHandlerFactory.registerSelfIgnoreError();
}
Dx warning: Ignoring InnerClasses attribute for an anonymous inner class (Acme.Serve.Main$1) that doesn't come with an associated EnclosingMethod attribute.
A: This has to do with the packaging of the HTTP Server library we're using in the Listener module. I think we can fix this by repackaging it properly in the future. For now it does not seem to cause any other problems and can be ignored.
A: Because Couchbase Lite defines views using native code, they must be provided to Couchbase Lite at runtime. However, the results of the map function are stored and re-used. When registering your view with Couchbase Lite they are given a name and version number. Views with the same name and version will reuse data already generated. So, when changing the implementation of your views it is important to bump the version number. See Couchbase Lite Ektorp Views for more information.
A: No. This indicates you are using the wrong source base.

| SUMMARY: NESTED | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
A collection of leases being managed by a lease renewal service.
Clients of the renewal service organize the leases they wish to
have renewed into lease renewal sets (or sets,
for short). These sets are represented by objects implementing this
interface. The
LeaseRenewalService.createLeaseRenewalSet
method is
provided to create sets. Sets are populated by methods on the sets
themselves. Two leases in the same set need not be granted by the
same service or have the same expiration time; in addition, they
can be added or removed from the set independently.
This interface is not a remote interface; each implementation of the
renewal service exports proxy objects that implement the
LeaseRenewalSet
interface that use an
implementation-specific protocol to communicate with the actual
remote server. All of the proxy methods obey normal RMI remote
interface semantics except where explicitly noted. Two proxy objects
are equal if they are proxies for the same set created by the same
renewal service. Every method invocation (on both a
LeaseRenewalService
and all the
LeaseRenewalSet
instances created by that server) is
atomic with respect to other invocations.
A number of the methods in this class throw
RemoteException
, each of these may throw the
java.rmi.NoSuchObjectException
subclass. If a client
receives a NoSuchObjectException
when calling a method
on a renewal set, the client can infer that the set has been
destroyed; however, it should not infer that the renewal service
has been destroyed.
The term client lease is used to refer to a lease that has been placed into a renewal set. Client leases are distinct from the leases that the renewal service grants on renewal sets it has created.
Each client lease has two expiration related times associated with it: the desired expiration time for the lease, and the actual expiration time granted when the lease was created or last renewed. The desired expiration represents when the client would like the lease to expire. The actual expiration represents when the lease is going to expire if it is not renewed. Both time values are absolute times, not relative time durations. When a client lease's desired expiration arrives, the lease will be removed from the set without further client intervention.
Each client lease also has two other associated attributes: a
desired renewal duration and a remaining desired
duration. The desired renewal duration is specified by the
client (directly or indirectly) when the lease is added to the
set. This duration must normally be a positive number, however, it
may be Lease.ANY
if the lease's desired expiration is
Lease.FOREVER
. The remaining desired duration is
always the desired expiration less the current time.
Each time a client lease is renewed, the renewal service will ask for an extension equal to the lease's renewal duration if the renewal duration is:
If a client lease's actual expiration is later than its desired expiration, the renewal service will not renew the lease; the lease will remain in the set until its desired expiration is reached, the set is destroyed, or it is removed by the client.
Each set is leased from the renewal service. If the lease on a set expires or is cancelled, the renewal service will destroy the set and take no further action with regard to the client leases in the set. Each lease renewal set has associated with it an expiration warning event that occurs at a client-specified time before the lease on the set expires. Clients can register for warning events using methods provided by the set. A registration for warning events does not have its own lease, but instead is covered by the same lease under which the set was granted.
The term definite exception is used to refer to an
exception that could be thrown by an operation on a client lease
(such as a remote method call) that would be indicative of a
permanent failure of the client lease. For purposes of this
document, all bad object exceptions, bad invocation exceptions, and
LeaseException
s are considered to be definite
exceptions.
Each lease renewal set has associated with it a renewal failure event that will occur in either of two cases: if any client lease in the set reaches its actual expiration before its desired expiration is reached, or if the renewal service attempts to renew a client lease and gets a definite exception. Clients can register for failure events using methods provided by the set. A registration for failure event does not have its own lease, but instead is covered by the same lease under which the set was granted.
Once placed in a set, a client lease will stay there until one or more of the following occurs:
Each client lease in a set will be renewed as long as it is in the set. If a renewal call throws an indefinite exception, the renewal service should retry the lease renewal until the lease would otherwise be removed from the set. The renewal service will never cancel a client lease. The preferred method of cancelling a client lease is for the client to first remove the lease from the set and then call cancel on it. It is also permissible for the client to cancel the lease without first removing the lease from the set, although this is likely to result in additional network traffic.
Client leases get returned to clients in a number of ways (via
remove
and getLeases
calls, as components
of events, etc.). In general, they should have their serial format
set to Lease.DURATION
before being transferred to the
client's virtual machine. In some exceptional circumstances, this
may not be possible (for example, the client lease was recovered
from persistent storage and could not be deserialized in the
server's virtual machine). In these cases, it is acceptable to
transfer the lease to the client using the
Lease.ABSOLUTE
serial format.
Whenever a client lease gets returned to a client, its actual expiration should reflect either:

public void renewFor(Lease leaseToRenew, long desiredDuration, long renewDuration) throws RemoteException
The leaseToRenew
argument specifies the lease to be
added to the set. An IllegalArgumentException
must
be thrown if the lease was granted by the renewal service
itself. If leaseToRenew
is null
, a
NullPointerException
must be thrown.
The desiredDuration
argument is the number of
milliseconds the client would like the lease to remain in the
set. It is used to calculate the lease's initial desired
expiration by adding desiredDuration
to the current
time (as viewed by the service). If this causes an overflow, a
desired expiration of Long.MAX_VALUE
will be
used. Unlike a lease duration, the desired duration is
unilaterally specified by the client, not negotiated between the
client and the service. Note, a negative value for
desiredDuration
(including Lease.ANY
)
will result in a desired expiration that is in the past, causing
leaseToRenew
to be dropped from the set; this action
will neither result in an exception or an event.
If the actual expiration time of leaseToRenew
is
less than the current time (as viewed by the renewal service) and
the current time is less than the desired expiration time for
leaseToRenew
, the method will return
normally. However, leaseToRenew
will be dropped from
the set and a renewal failure event will be generated.
The renewDuration
is the initial renewal duration to
associate with leaseToRenew
(in milliseconds). If
desiredDuration
is exactly
Long.MAX_VALUE
, the renewDuration
may
be any positive number or Lease.ANY
; otherwise it
must be a positive number. If these requirements are not met, the
renewal service must throw an
IllegalArgumentException
.
Calling this method with a lease that is equivalent to a client
lease already in the set will associate the existing client lease
in the set with the new desired duration and renew duration. The
client lease is not replaced because it is more likely that the
renewal service, rather than the client, has an up-to-date lease
expiration. The service is more likely to have an up-to-date
expiration because the client should not be renewing a lease that
it has passed to a lease renewal service unless the lease is
removed first. These semantics also allow renewFor
to be used in an idempotent fashion.

- if one or more of the leases can

LeaseUnmarshalException
represents a,
possibly transient, failure in the ability to unmarshal
one or more client leases in the set, it does not
necessarily imply anything about the state of the renewal
service or the set themselves.
RemoteException
- if a communication-related exception
occurspublic EventRegistration setExpirationWarningListener(RemoteEventListener listener, long minWarning, MarshalledObject handback) throws RemoteException
This method allows the client to register for notification of
the approaching expiration of the set's lease. The
listener
argument specifies what listener should
be notified when the lease is about to expire. The
minWarning
argument specifies a minimum number of
milliseconds before lease expiration that the first event
delivery attempt should be made by the service. The service may
also make subsequent delivery attempts if the first and any
subsequent attempts have been indeterminate. The
minWarning
argument must be zero or a positive
number; if it is not, an IllegalArgumentException
must be thrown. If the current expiration of the set's lease is
less than minWarning
milliseconds away, the event
will occur immediately (though it will take time to propagate
to the listener).
The handback
argument to this method specifies an
object that will be part of the expiration warning event
notification. This mechanism is detailed in the Jini(TM)
Distributed Event Specification.
This method returns the event registration for this event. The
Lease
object associated with the registration will
be equivalent (in the sense of equals
) to the
Lease
on the renewal set. Because the event
registration shares a lease with the set, clients that want to
just remove their expiration warning registration without
destroying the set should use the
clearExpirationWarningListener
method instead of
cancelling the registration's lease. The registration's event
ID will be
LeaseRenewalSet.EXPIRATION_WARNING_EVENT_ID
. The
source of the registration will be the set. The method must
throw a NullPointerException
if the
listener
argument is null
. If an
event handler has already been specified for this event the
current registration is replaced with the new one. Because both
registrations are for the same kind of event, the events sent
to the new registration must be in the same sequence as the
events sent to the old registration.

This method allows the client to register for the event associated with the failure to renew a client lease in the set. These events are generated when a client lease expires while it is still in the set, or when the service attempts to renew a client lease and gets a definite exception. The listener argument specifies the listener to be notified if a client lease could not be renewed.
The handback
argument specifies an object that
will be part of the renewal failure event notification. This
mechanism is detailed in the Jini(TM) Distributed Event
Specification.
This method returns the event registration for this event. The
Lease
object associated with the registration will
be equivalent (in the sense of equals
) to the
Lease
on the renewal set. Because the event
registration shares a lease with the set, clients that want to
just remove their expiration warning registration without
destroying the set should use the
clearRenewalFailureListener
method, instead of
cancelling the registration's lease. The registration's event
ID will be
LeaseRenewalSet.RENEWAL_FAILURE_EVENT_ID
. The
source of the registration will be the set. The method must
throw NullPointerException
if the
listener
argument is null
. If an
event handler has already been specified for this event the
current registration is replaced with the new one. The returned
event registration must have the same event ID as the replaced
registration. Because both registrations are for the same kind
of event, the events sent to the new registration must be in
the same sequence as the events sent to the old registration.

How does one prove 1 = n + 1 - n
, without getting your hands dirty? Do we have anything that can help with nat.sub
?
Can't linarith
do these by now?
git grep ". + . - ." algebra/group.lean: lemma add_sub_cancel' (a b : α) : a + b - a = b := algebra/ring.lean: ... ↔ a * e + c - b * e = d : iff.intro (λ h, begin simp [h] end) (λ h, data/list/basic.lean: reverse (range' s n) = map (λ i, s + n - 1 - i) (range n) data/multiset.lean:theorem add_sub_cancel_left (s : multiset α) : ∀ t, s + t - s = t := data/multiset.lean:theorem add_sub_cancel (s t : multiset α) : s + t - t = s := data/multiset.lean:by simpa [(∪), union, eq_comm] using show s + u - (t + u) = s - t, data/nat/basic.lean: ... ≤ n + m - n : nat.sub_le_sub_right this n data/nat/prime.lean: sqrt n - k < sqrt n + 2 - k := data/nat/prime.lean: λ _ _, `[exact ⟨_, measure_wf (λ k, sqrt n + 2 - k)⟩]} data/nat/prime.lean: λ _ _, `[exact ⟨_, measure_wf (λ k, sqrt n + 2 - k)⟩]} data/padics/padic_norm.lean: padic_norm hp q = padic_norm hp (q + r - r) : by congr; ring data/padics/padic_rationals.lean: show lim_zero (f + g - g), by simpa using hf }, data/padics/padic_rationals.lean: show lim_zero (f + g - f), by simpa [add_sub_cancel'] using hg }, docs/naming.md:pattern. For that, we make do as best we can. For example, `a + b - b = a` group_theory/subgroup.lean:(normal : ∀ n ∈ s, ∀ g : α, g + n - g ∈ s) set_theory/ordinal.lean:theorem add_sub_cancel (a b : ordinal) : a + b - a = b := set_theory/ordinal.lean:theorem add_sub_add_cancel (a b c : ordinal) : a + b - (a + c) = b - c := tests/linarith.lean: (h4 : a + b - c < 3) : false := tests/linarith.lean:example (a b c : ℚ) (h2 : (2 : ℚ) > 3) : a + b - c ≥ 3 := tests/ring.lean:example {α} [comm_ring α] (x y : α) : x + y + y - x = 2 * y := by ring
No, linarith doesn't help.
Or even better:
git grep ". + . - ." | grep nat data/nat/basic.lean: ... ≤ n + m - n : nat.sub_le_sub_right this n data/nat/prime.lean: sqrt n - k < sqrt n + 2 - k := data/nat/prime.lean: λ _ _, `[exact ⟨_, measure_wf (λ k, sqrt n + 2 - k)⟩]} data/nat/prime.lean: λ _ _, `[exact ⟨_, measure_wf (λ k, sqrt n + 2 - k)⟩]}
For it to deal with subtraction on natural numbers it would have to break into cases.
That first result looks promising
nat.add_sub_cancel_left
@Scott Morrison Is :up: what you need?
Yeah, but even that requires using commutativity of addition first.
Too gross for me. :-)
They don't need that over here:
git grep -A1 ". + . - ." | grep -A1 nat | head -2 data/nat/basic.lean: ... ≤ n + m - n : nat.sub_le_sub_right this n data/nat/basic.lean- ... = m : by rw nat.add_sub_cancel_left,
Seems like rw
will do the job.
All of these lemmas are in Lean or mathlib I think. I've extensively used subtraction on nats and am not aware of any holes.

mocha is a JavaScript test framework running on Node.js and in the browser.
Version for this test.
"mocha": "5.1.1"
"node": "9.2.1"
Inside a
describe
, before
will execute **once** before **all tests** inside this describe
including nested tests.
Inside a describe
, beforeEach
will execute **once** before **every test** inside this describe
including nested tests. In other words, if there are **N** tests in total (including nested tests), beforeEach
will execute **N** times in total.
The output is
The outer before(1)
executed once.
The outer beforeEach(1)
executed 5 times, since there are 5 tests(`inner test1`, `inner test2`, `outer test1`, `outer test2`, `outer test3`) in total within the
beforeEach(1)
.
The inner beforeEach(2)
executed twice, since there are 2 tests(`inner test1`, `inner test2`) within the beforeEach(2)
.
Hope this blog could help you understand the before, beforeEach, after, afterEach, it
mocha test.

Problem Description:
In this problem, phone’s screen is divided into 4 vertical strips. Every second, a black square appears on some of the strips.
Four integers \(a_1, a_2, a_3, a_4 (0 \le a_1, a_2, a_3, a_4 \le 10^4) \) are given. \(a_i\) calories are wasted on touching the \(i^{th}\) strip. (\(a_1\) indicates the calories needed for touching \(1^{st}\) strip, \(a_2\) indicates the calories needed for touching \(2^{nd}\) strip and so on.)
A string \(s (1 \le |s| \le 105)\) is given. \(s\) simply indicates the number of strip where the black square appears. For example, \(s = 112314\) means \(1^{st}\) black square appeared on \(1^{st}\) strip, then on \(1^{st}\) strip again, then on \(2^{nd}\) strip, on \(3^{rd}\) strip, \(1^{st}\) strip and then on \(4^{th}\) strip.
We have to calculate how many calories are needed to destroy all the squares.
Ideological Analysis:
There are 4 strips and \(a_1, a_2, a_3, a_4\) contains the number of calories.
\(s\) contains the strip number where the black square appears. So, simply we can count how many times black square appeared in each strip. And then multiply it with the calories required to touch the strip. We have to do this for all four strips and add them all.
Example:
$$a_1 = 4, a_2 = 1, a_3 = 2, a_4 = 5\space $$ $$and$$ $$s = 2141231$$
Here, Three \(1\)s, two \(2\)s, one \(3\), and one \(4\) in string \(s\). So, we can the total number of calories required to destroy all black squares by weighted sum of them. Such as,
$$ \sum\limits_{i=1}^4 {a_i * COUNT(i)\space in\space s}$$ $$= 3*4 + 2*1 + 1*2 + 1*5 $$ $$= 21$$

--- title: easy git for beginners author: ~ date: '2017-12-17' slug: easy-git-for-beginners-rmd categories: [] tags: - code - git - beginner - tutorial description: '' ---
I recently started using git, github (the online UI counterpart) and bitbucket (at work, similar to github). It’s a powerful tool to organize your work and makes it fairly easy (if opening up the cmd prompt/terminal is your thing) to collaborate with others on coding projects. For true beginners download the free Pro Git book and read chapters 1 - 3. It will cover setup, what git is, and almost everything I’m about to say. You can think of the version below as the hyper-abridged version.
After initial set up, noodling around, and creating a few repos/branches, I noticed I kept getting lost in which branch I was on. The “easy” way to save yourself from this is to check where the git HEAD is pointed. That is how git knows where it’s located and why you don’t have to type the name of the branch you’re currently in. Use the command “git log --oneline --decorate”.
What’s happening in the output? The HEAD is pointed to master. Any commits I make will go to the master repo. I could change the pointer using git checkout origin/master
. The origin/HEAD branch is created from using a remote (see Why is “origin/HEAD” shown when running “git branch -r”?).You’ll be able to figure out 80% of your issues if you know which repo you’re in and whether it’s the local or remote version.
Now, what if you forget which one is local and which is remote? Use git branch
for local and git branch -r
to view remote.
My local branch is called master and the two remotes show up.

Some news of who's in and out has been dribbling out, and the list of friendlies is now available.
First the player news. Woody and Ralphy Crisp are both out , rejecting 'reduced terms'. They both been tree-mendous players for the club, and will be sorely missed. Other leavers are James Ince, Jon Ford and I believe Jason Owen .
Definite (as far as I know) to stay are Dennis Bailey, Les Hines, Jason Burnham, Stuart Skidmore and Ross Collins . Finally, Andy Quy, Peter Sutton and Clinton Thomas have been asked to prove their fitness at pre-season training.
As ever, if anyone knows any different either mail me or post a message on YeltzTalk .
The list of pre-season friendlies has been announced - quite an interesting list including Stourbridge Town, Kiddy, Albion and Blues. First game is on July 14th, so there's a bit to go yet :-(

My friends and I were finishing up our freshman year and had decided that we were going to end it right with one last crazy weekend. Our drug of choice for the past couple of months had been E, so we managed to find some tablets from a friend that were highly recomended. We drove an hour and a half away from school to my friend's boyfriend's private beach house. When we got there realized that we had forgotten to get cigaretts so we sent one of our friends out to buy a carton. Because it was getting late, around 2 am, we decided to take the pills first, thinking that she would have time to go to the store and back before the effects really started to hit here. So we popped them, she left, and the rest of us wwent out to the deck with couch cushions and pillows to make a huge bed under the stars.
About fifteen minutes after taking the pills we began to feel the effects. Things were harder to move. Everything felt so surreal. We all kinda looked at eachother and realized that the pills were really strong and that we were already starting to roll. Our friend arrived clutching our cigaretts and her 'fuzzy blankie' and we all sat down on the cusions and began to give messages. About 30 min later we decided to venture down to my friend's boyfriend's car to watch a DVD we had gotten from the museum of science of all of these amazing pictures of space with relaxing music in the background. It was amazing. We were just sitting there on this private island having the best roll of our lives.
Around four thirty we decided to move down to the beach. The sand and breezes and sounds of the occean were amazing. We all sat and talked about how much we loved eachother and how much we were going to miss eachother. The sky began to brighten and we witnessed the most breath-taking sunrise I have ever seen. When we realized what time it was we were surprised that we were stiill rolling as hard as we were. Nothing has lessedned in intensity. I decided to go walk the beach and find shells. Florida shells are so beautiful and soft and smooth so I was having a truly great time when my freiends yelled to me to come back. We waded into the water and, just as we were, pods of dolphins began swimming around us. It was like being in a magical kindom where anything was possible and everything was amazing.
The weekend was a perfect way to end an amazing year and it made it almost more special because some of us were leaving at the end of the year. just wanted to share my best-ever roll. ~ciao~

Hi All,
I see that there are implementations of search strategies of DFS and BAB in Gecode system. But, if I want to implement a customized search engine, like mySearch in a file mySearch.hh. How should I update the configure files so that the newly generated Makefile can have my lds.hh file compiled? Thanks a lot!

Theming Improvments
Theming support in this release has change significantly and all the new features are covered in detail in the following guides:
- Customization Overview - provides a high level introduction to all the customization and theming options now provided by Spree.
- View Customization - introduces and explains how to use Deface to customize Spree’s views.
- Asset Customization - explains how Spree uses Rails’ new asset pipeline, and how you can use it to customize the stylesheets, javascripts and images provided by Spree.
While the upgrade instructions that follow briefly cover the new asset pipeline features we suggest you review the guides above as part of your upgrade preparation.
Themes as engines
In previous versions (0.11.x and earlier) Spree encouraged the approach of bundling themes in their own extensions, with the advent of the asset pipeline in Rails 3.1 and the upcoming Theme Editor we’re bringing back this approach as a suitable model for distributing and sharing themes.
While the distinction between themes and extensions is covered in the Extensions & Themes guide they are both just Rails engines and can be treated as such.
We’ve created two front-end themes to help show this new approach in action:
-
Spree Blue - Recreates the original “blue” theme of 0.60.x as a stand alone theme.
-
Rails Dog Radio - This recreates some of the aspects of the Rails Dog Radio demo application for a default Spree application.
Both themes can be installed by just adding a reference to the git repository to your Gemfile, ie:
gem 'spree_blue_theme', git: 'git://github.com/spree/spree_blue_theme.git'
Experimental SCSS/SASS Theme
LESS proves to be unpopular amongst Spree developers so it is decided to
retire LESS stylesheets of spree_blue_theme
in favor for all-in-one
screen.css
.
Yet with the recently adopted SCSS/SASS in Rails 3.1, we believe this technology could become de-facto standard for CSS someday. Thus, we create the experimental SCSS/SASS version of spree_blue_sass_theme to collect feedbacks before we could come up with a decision to opt for SCSS/SASS in future version of Spree.
The Asset Pipeline
One of the more interesting new features included in Rails 3.1 is the asset pipeline, and a lot of the customization improvements in Spree are enabled by this feature. While the asset pipeline provides excellent flexibility and improved organization for all of Spree’s assets (images, javascripts and stylesheets) it does add a significant overhead as all asset requests are now being handled by Rails itself (and not being handed off to the web server).
This can be especially noticeable in development mode when using a single process application server like Webrick. This release of Spree includes a small tweak to the standard pre-compiling rake task that allows pre-compiling of assets for development mode.
Pre-compiling in production
Rails supports pre-compiling of assets which is intended to offload the overhead of generating and serving assets from the application server in production environments.
Pre-compiling is not required for the asset pipeline to function correctly in production, if you choose to not pre-compile Rails will generate each asset only once and serve each subsequent request using Rack::Cache.
Rack::Cache is generally sufficient for lower traffic sites, but pre-compiling will provide some additional speed increases by allowing the web server to serve all assets, including gzipped versions of javascript and css files.
To pre-compile assets for production you would normally execute the following rake task (on the production server).
$ bundle exec rake assets:precompile
This would write all the assets to the public/assets
directory while
including an MD5 fingerprint in the filename for added caching benefits.
In production all references to assets from views using image_tag, asset_path, javascript_include_tag, etc. will automatically include this fingerprint in the file name so the correct version will be served.
Pre-compiling for development
Spree alters the behaviour of the precompile rake task as follows:
$ bundle exec rake assets:precompile:nondigest
It will still output the assets to public/assets
but it will not
include the MD5 fingerprint in the filename, hence the files will be
served in development directly by the web server (and not processed by
Rails).
Using the precompile rake task in development will prevent any changes to asset files from being automatically included in when you reload the page. You must re-run the precompile task for changes to become available.
Rail’s also provides the following rake task that will delete the entire
public/assets
directory, this can be helpful to clear out development
assets before committing.
$ bundle exec rake assets:clean
It might also be worthwhile to include the public/assets
directory in
your .gitignore
file.
Promotions
Promotions have been extended well beyond their coupon roots to include
new activator
support, which can now fire or activate a promotion for
a variety of different user triggered events, including:
- Adding items to a cart
- Visiting specific pages
- Adjusting cart contents
- Using a coupon code
Promotions also includes a new Actions
feature which can perform an
action as a result of a promotion being actived, these actions currently
include creating an adjustment or adding additional items to a cart.
For more details on these new promotions feature please refer to the Promotions guide.
New Extension Generator
There is a new extension generator available as part of this release. The generator is utilized by a new executable contained within the gem.
You can generate new extensions inside an existing rails application or as a standalone git repository using the following command
$ spree extension foofah
One of the most important advances in this new generator is that you can now easily run specs for extensions in their own standalone repository. You just need to create a test application (one time only) as a context before running your specs.
$ bundle exec rake test_app $ bundle exec rspec spec
You can get more information on the extension generator in the Creating Extensions guide.
You must install the spree gem in order to use the new extension generator.
Upgrade Instructions
These instructions are mainly concerned with upgrading Spree applications, extension developers should jump straight to the “Asset Customization”asset_customization.html and View Customization guides for details on the changes that are required for extensions to fulling support 0.70.0.
Before you begin
To prevent problems later please ensure that you’ve copied all the migrations from your current version of Spree and all the extensions that you are running. While this is normal practice when setting up Spree and extensions any missing migrations will cause issues later in the upgrade process.
You can check that all Spree migrations are copied by running:
$ bundle exec rake spree:install:migrations
Each extension will provide it’s own rake task (or generator) for copying migrations so please refer to the extensions README for instructions.
It’s vital that you confirm this first before starting the upgrade process as Rails 3.1 has altered how engine migrations are handled and incorrectly copying migrations later could result in data loss.
Changes required for Rails 3.1
Most of the changes required to upgrade a Spree application to 0.70.0 is same for any Rails 3.0.x application upgrading to 3.1.
Gemfile changes
You’ll need to make several additions and changes to your Gemfile:
- Update spree to 0.70.0
- Update rails to 3.1.1
- Update mysql2 to 0.3.6 - if your using it.
- Ensure the assets group is present:
group :assets do gem 'sass-rails', "~> 3.1.1" gem 'coffee-rails', "~> 3.1.1" gem 'uglifier' end
Update config/boot.rb
Rails 3.1 simplifies the config/boot.rb
file significantly, so update
yours to match:
require 'rubygems' # Set up gems listed in the Gemfile. ENV['BUNDLE_GEMFILE'] ||= File.expand_path('../../Gemfile', *FILE*) require 'bundler/setup' if File.exists?(ENV['BUNDLE_GEMFILE'])
Enable the asset pipeline
Add the following line to config/application.rb
, this will enable the
Asset Pipeline feature (required by 0.70.0):
config.assets.enabled = true
Remove deprecated configuration
Remove the following line from config/environments/development.rb
.
config.action_view.debug_rjs = true
Retire lib/spree_site.rb
The spree_site.rb file is no longer required so it’s important to migrate any existing code out of this file and into the correct location.
- Model, controller or helper evals should be relocated to a suitable _decorator.rb file.
- Configuration settings should be moved to initializers.
- If you are activating custom Abilities or Calculators, you should
remove then for now. You can re-add them to config/application.rb
after you’ve ran the spree:site generator below. They will need to
be inside the
config.to_prepare
block.
The decorator initialization block will be automatically included in config/application.rb for you, when you run the spree:site generator below.
Remove spree_site from config/application.rb
Also ensure the following line is not present in config/application.rb:
require 'spree_site'
Update gems & generate Spree files
Once you’ve completed all the Rails 3.1 steps above, you can now update your dependencies and start generating the new asset pipeline placeholders.
Install dependencies
Install all the required gems, and lock your dependencies by running:
$ bundle update
Generate & copy required files
Running the spree:site
generator will create the skeleton structure
for the asset pipeline, and also copy missing migrations.
$ rails g spree:site
After running the generator above, it’s best to check to make sure you
do not have multiple copies of the following line, in
config/application.rb
:
config.middleware.use "RedirectLegacyProductUrl" config.middleware.use "SeoAssist"
Update your database
If you encounter any issues with this step please ensure you’ve completed the Before you begin section above.
Make sure you’ve taken a backup of the database before attempting this step.
$ bundle exec rake db:migrate
Migrating your assets
Cleaning up your /public
directory is one major advantage of using
Rails 3.1. The main task required here is to separate your application
specific assets (javascript, stylesheets and images) from all of Spree’s
(and all those belonging to all the extensions installed) which have
been mingled together in your public directory.
Asset Organization
Assets should be placed inside your application in one of three
locations: app/assets
, lib/assets
or vendor/assets
.
app/assets
is for assets that are owned by the application, such as
custom images, JavaScript files or stylesheets.
lib/assets
is for your own libraries’ code that doesn’t really fit
into the scope of the application or those libraries which are shared
across applications.
vendor/assets
is for assets that are owned by outside entities, such
as code for JavaScript plugins.
If you are using a library like Jammit solely for concatenating and minifying your javascript and stylesheet files then we suggest you remove it from your application as part of the Rails 3.1 upgrade.
For a full explanation of how Spree uses Rails’ asset pipeline and how to update your site to use these new features please refer to the Asset Customization guide.
Cleaning up /public
Once you’ve relocated all your applications assets, the only
remaining directories and files in /public
should be images that
you’ve uploaded for your Products (or taxonomies). If you are using the
default Spree configuration these will be in /public/assets
.
Leaving any javascript, stylesheet or image files in the public
directory will override those provided by Spree or it’s extensions. So
it’s vital that you delete all remaining files from the /public
directory, EXCEPT YOUR PRODUCT IMAGES!.
If you are using S3 (or another cloud storage system) for your
Product images then your /public
directory should be completly empty.
Including old style theming hooks
With the introduction of Deface the old style theming hooks have been deprecated, the old hooks will continue to function after the upgrade as they are automatically upgraded to Deface overrides, we strongly suggest you upgrade them as soon as possible.
To include your previously defined old style theming hooks from
lib/site_hooks.rb
add the following to the bottom of
config/application.rb
require 'lib/site_hooks'
The development log will include suggested replacement Deface overrides anytime Rails encounters a old style hook call. These suggestions are a best effort replacement, but might need some tweaks as some elements have been moved while removing the old hook calls from Spree’s view files.
For more information about using Deface overrides, please refer to the View Customization guide.
New way to register Calculators
Calculators no longer can be registered with register method. The register method is refactored to take advantage of default Rails application configuration Rails.application.config.spree.calculators.
For more information about this new change, please refer to the Ajustments guide.


The following example shows a table widget we specified in FTL, found parallelism in, and generated an HTML5 engine: the picture below is a live run of the engine!
The widget is defined mostly in standard FTL. Two parts are not; we are experimenting with extensions to handle them and, as is, they provide a good lesson in how to mix with foreign code.
The idea is that we work with the synthesizer and code generator. In developing this demo, we actually did not the final parallelization scheme: it found the basic schedule, and as we modified the code, ensured we didn't violate the scheme. In fact, near the end of the experience, we used the synthesizer to find a shorter schedule than what we working with throughout most of the initial development! Furthermore, we try to stay in FTL as much as possible because of the code generation benefits: the code shown here can be (provably) automatically parallelized and incrementalized.
Standard FTL
A fairly small specification language was used to specify most of the example.
ADTs
The example highlights that we do not need to define all of the functions in FTL. For example, min and max are JavaScript library calls: FTL assume any unknown function is pure.
 We use them here to compute the column and row number for each cell, such as with call appendIntPairList. We believe a similar strategy is possible for tracking floats.
There a pros and cons of using external functions for optimization. The drawback is that we will not optimize the memory of external code (e.g., to guarantee that it uses a parallel malloc) and vectorization may suffer. However, FTL's primary optimizations still apply: it could still automatically parallelize and incrementalize calls into the foreign code.
External constraints
We told the synthesizer about the constraints induced by our external library code:
schedule { "asserta(assignment(cols, self, intrinsprefwidth, self, cellsready)), ... P = [(_,td,_,_,_),(_,td,_,_,_),(_,bu,_,_,_),(_,td,_,_,_),(_,td,_,_,_),(_,bu,_,_,_),(_,td,_,_,_)]" }The constraints are written in standard Prolog.
At a high level, the first statement says there is a dependency not visible in the basic widget spec. More on this below. The second line says that we want to synthesize a particular schedule of 7 top down (td) and bottom up (bu) tree traversals. External code will monkey patch the traversal schedule, which is why we tell the synthesizer to look for this specific schedule. Overall, this example shows one clean way to guide the synthesizer to incorporate external knowledge and respect external constraints.
DAGs, not trees
The first line of the schedule constraint addresses the issue that we need to extend FTL to compute over DAGs, not just trees. Ideally, we wanted to write:
class Col(...) : ColI { children { childs : [ CellI ] = ../rows/childs[.column == self.colNum]; } ... }This would define the cells of a column as the cells of rows where the column numbers match, implying a DAG. The analyzer would track that column cells cannot be immediately computed. Likewise, the synthesizer should know that the column cannot compute over its cells until they are known.
However, the current version of FTL only supports trees, not DAGs. Thus, we created attribute cellsready to mean that the cells have been found. In the scheduling constraint above, we added a dependency on various column attributes on cellsready (such as for intrinsprefwidth), meaning they cannot be scheduled until after cellsready. We are working on expressive extensions to enable referencing non-local children. We use external code (monkey patching) to perform the actual aliasing; the constraint here is about ensuring the otherwise correct code is generated.
Our workaround for DAGs involves guiding the code generator: it should not generate code for attributes that the external code claims to solve. To pass our specification verifier, both a Row and a Column have to assign all of the attributes of a cell. Our synthesizer does not support DAGs, only trees: for each cell, it assumes the parent is row XOR col. The synthesizer would fail on the correct specification (row defines cell x position and col defines cell y position) because the row does not specify both cell (x,y) nor does the col. We know the external code will handle these cases, so we include, as part of the specification, phantom attributes for rows and columns: they will be assumed to be solvable at any time and no code will be emitted.

Samsung pushes another Android 10 beta for the Galaxy S10 series
by MichailSamsung has begun seeding its newest Android 10 beta for the Galaxy S10 series. This is the fourth since the One UI 2.0 beta program began.
The German version, in particular, comes with the G97**XXU3ZSK9 build number and weighs in at just over 344 MB. It brings a slew of bug fixes that tackle screen flickering problems, status bar issues, keyboard and other UI problems.
Samsung has already closed its One UI 2.0 beta program in South Korea, which signals that it is close to releasing the stable build soon. That all depends on the number of bugs left to fix after the latest beta release.

Polkit-0.116
Installation of Polkit
There should be a dedicated user and group to take control of the
polkitd daemon after
it is started. Issue the following commands as the root
user:
groupadd -fg 27 polkitd &&
useradd -c "PolicyKit Daemon Owner" -d /etc/polkit-1 -u 27 \
-g polkitd -s /bin/false polkitd
Fix an issue introduced in recent Polkit realeases with elogind:
patch -Np1 -i ../polkit-0.116-fix_elogind_detection-1.patch &&
autoreconf -fi
Install Polkit by running the
following commands:
./configure --prefix=/usr \
--sysconfdir=/etc \
--localstatedir=/var \
--disable-static \
--with-os-type=LFS \
--enable-libsystemd-login=no &&
make
To test the results, issue: make
check. Note that system D-Bus daemon must be running for the testsuite
to complete.
Now, as the root
user:
make install
Command Explanations
--with-authfw=shadow
: This switch
enables the package to use the Shadow rather than the Linux PAM Authentication framework. Use it if
you have not installed Linux PAM.
--disable-static
: This
switch prevents installation of static versions of the libraries.
--enable-gtk-doc
: Use this parameter if
GTK-Doc is installed and you wish
to rebuild and install the API documentation.
--enable-libsystemd-login=no
: This
switch forces polkit to build with elogind support (if available)
rather than systemd.

I have chosen to use the following fonts for my site:
I find animals to be fascinating. A lot of unique animals don’t get the attention they deserve, and I want people to find them as fascinating as I do. I’m familiar with building websites, and want to build one that gives information on less popular animals. It would be informationally rich, and feature images and explanations on special features they have. This would be original because it’s focus would be on animals that don’t ever get the spotlight. Wouldn’t you be interested to learn about animals you’ve never even heard of, like the aye aye, tarsier, and mantis shrimp? What about unspoken facts about animals you do know like the kangaroo, octopus, or chameleon? My website could give people that opportunity.
The purpose of my website will be to create an environment of learning about the more unseen parts of the animal kingdom. Sharing information will be the basis of this website, serving as a compilation of facts from animals both popular and hidden that can inspire people about the wonders of nature. By doing so, we hope to increase interest in zoos and other events centered around animals. By pouring more revenue into the animal industry, more will inevitably be used to help wildlife in need and people will have more access to seeing and experiencing these surprisingly complex creatures.
This website is going to be geared towards a slightly mature audience, mainly teens and above. They’ll need the maturity and capacity to understand the content, and the teenage age group is probably most likely to visit a site with this content. They will be interested in the novelty of interesting information, and likely possess a casual love for animals already. This website will likely be accessed through laptop and mobile device the most frequently, and as the purpose suggests, they will be seeking information they didn’t know about popular animals, and information on animals they weren’t even aware of.
Our mission is to foster an environment of learning and curiosity, as well as support the quality of our planet and all of its inhabitants. We plan to do so by sparking the minds of people by educating them about unique animals with special abilities. This will in turn provide the world with ways to connect over common interests and motivate individual and community growth. It will also more subtly promote a green lifestyle so that we can save and preserve the animal kingdom and improve our own standard of living. We value and actively encourage learning, environmental awareness, and wildlife, and seek to spread those values.

Version Control is especially useful when collaborating with a number of people on one specific task. Version control contributes to clarity in code and diminshes any chance of overwrite by collaborating piers. This ingenious invention has made open source coding possible for everyone around the world who wishes to contribute code taylored to their needs.
Git is a device that derives from this concept of version control. Git stores all changes you have made to a file in a log. Every change you make in a file it is stored on the local computer and can be accessed any time.
GitHub is the most useful medium to store code because it contributes to a collaborative experience that software engineering inherently embodies. This medium makes tracking changes on the internet and boundless contributions to code possible. It is by far the most populat hub in which coders share and tweak code finely tuned to their needs.

Yamaha 4-Operator FM Synthesizer Family
Multimode Patch Editor (TX81Z and DX11 only)
This editor is designed for multimode patches from the Yamaha TX81Z and DX11. The V50 should be easy to get up and running as well, but I have nothing to test with. If you have a V50, contact me (sean@cs.gmu.edu).
There are some later 4-Op synthesizers (YS100, YS200, B200, etc.) which support a simple kind of multimode, but as a global system setting, not as a patch. At present I have elected not to support these synthesizers.
Communicating with Edisyn
Set your synth's receive and transmit channel to the same thing (perhaps Channel 1), and set Edisyn's Send and Receive channels to that as well. Set the program change to be Com (Common). Make sure that Sysex is turned on.
Bank Sysex
This patch editor knows about bank sysex messages (which group together multiple patches) as well as single-patch sysex messages. If Edisyn loads or receives a bank sysex message, you will be given the option to edit a patch from it, to save the whole bank sysex, or to upload the whole bank sysex.
Gotchas
- The TX81Z is notorious for getting in corrupted states when receiving MIDI transmissions, either because of buffer overflows ("MIDI Buffer Full!") or just messing up. Performance Mode seems to be the worst at this. I'm working on minimizing these, but you'll still see them. If this happens, or if Edisyn doesn't seem to be receiving data correctly or is displaying data wrong, press the Play/Performance button to go out into Single patch mode, move to another patch temporarily (press Right and then Left, say) to clear the performance data, and try again. Let me know.
-
4-op synthesizers like the DX11 and TX81Z have no way to write patches from sysex: you will have to send the current patch from Edisyn, then manually save it to your desired patch location on the synthesizer itself.
- Similarly, changing patches is challenging: it requires a bit of manipulation of the front panel using special sysex options. It should work in general, but if strange things happen, let me know.
Librarian Support
The Yamaha 4-Op machines cannot write individual patches: if you attempt to do so from the librarian you'll be told that you cannot. Instead, you should write the entire bank.
Edisyn can quick-request a bank from this synthesizer via Request Bank from Synth. This is a lot faster than the patch-by-patch request method in Download Bank from Synth. So try it out.
Thanks

Israel Will Reap the Whirlwind
1 Set the trumpet to your lips!
One like a vulture is over the house of the LORD,
because they have transgressed my covenant
and rebelled against my law.
2 To me they cry,
My God, we—Israel—know you.
3 Israel has spurned the good;
the enemy shall pursue him.
4 They made kings, but not through me.
They set up princes, but I knew it not.
With their silver and gold they made idols
for their own destruction.
5 I have spurned your calf, O Samaria.
My anger burns against them.
How long will they be incapable of innocence?
6 For it is from Israel;
a craftsman made it;
it is not God.
The calf of Samaria
shall be broken to pieces.
7 For they sow the wind,
and they shall reap the whirlwind.
The standing grain has no heads;
it shall yield no flour;
if it were to yield,
strangers would devour it.
8 Israel is swallowed up;
already they are among the nations
as a useless vessel.
9 For they have gone up to Assyria,
a wild donkey wandering alone;
Ephraim has hired lovers.
10 Though they hire allies among the nations,
I will soon gather them up.
And the king and princes shall soon writhe
because of the tribute.
11 Because Ephraim has multiplied altars for sinning,
they have become to him altars for sinning.
12 Were I to write for him my laws by the ten thousands,
they would be regarded as a strange thing.
13 As for my sacrificial offerings,
they sacrifice meat and eat it,
but the LORD does not accept them.
Now he will remember their iniquity
and punish their sins;
they shall return to Egypt.
14 For Israel has forgotten his Maker
and built palaces,
and Judah has multiplied fortified cities;
so I will send a fire upon his cities,
and it shall devour her strongholds.

Welcome to the site? There's coffee brewing in the kitchen, but you're probably here for the content.
Implementation Types of CSS
This is blue, with a small margin. In other words, an example of Inline text.
This is an example of that (Horrible looking) Internal CSS.
Code for the cards. (External Example)
But in larger systems of CSS, like bootstrap, '.min' files exist which contain all of bootstraps CSS in a conveinient small package. Not good for human reading, but for the device you are viewing the site on, its perfect.
Thats a lot of code for 14 lines.
Just remember:
CSS, Also known as Cascading Style Sheet or "WHY IS IT NOT WORKING" before realising you forgot to link it, is a great way of changing content flow colour... And just about everything.
As the poster shows, a traditional CSS box Model Contains its content within padding, border, and a margin. These are all adjustable, and are usually just used to ensure everything is spaced out normally.
For instance, we could set div (therefore anything in a div too) to always be 300px wide, have a 25px thick green border, and add 25px to margin and padding, like so:
Or, if I wanted to only affect one div...
Alternatively, we can create a custom class in the internal or external CSS that we can apply to whichever div's we choose.
But what about that code in action? Here it is, inline:
Hello there!
Scripting Languages allow users to write a program for a computer to interpret and run. Computers can only understand code, so scripting languages tend to be the middle ground between machine-friendly code and human-readable.
Variables are the "bread and butter" of any coding language. They can store data to be used later, whether its for a calculation, to print specific text, to be saved to a file, or launched into the infinite void of space.(i.e. deleted)
Variables come in all sorts of formats, and their formats can be changed on the fly. For instance:
Its worth noting that by default, most things are stored as "strings"(not shown on the image) Which can store virtually anything, and treats it as plain text.
Functions are also a commonly used thing within a scripting language to do... anything. Chances are, everything you do will be contained within a function of some sort.
If we take Python as an example, you can either 'def'(define) a function, or use 'async def'(which allows the function to be ran simultaneously with others)
For example, if we were to take this code Snippet from "Red-Discord Bot":
From here.The code, in short:
Although there is more, I've only highlighted the main parts. And when the function is called...
In this section I am going to assess different implementation styles for CSS. The different implementation styles in which I am going to talk about include: Internal Style Sheets, External Style sheets and Inline Style sheets. CSS (Cascading Style Sheets) allows a web developer to design a website in terms of the colour and design. CSS does not "create" anything all it does it decorates and align stuff on the web page. HTML (Hyper Text Mark-up Language) is responsible for the construction and the total output of a web page. As mentioned earlier there are three sections in HTML and I will go in more detail below. The main job of styles is to define what the HTML elements will look like; therefore CSS is built into all HTML tags.
There’s 3 types of CSS to choose from - Inline, which is quick and simple, Internal, which affects an entire page, and External, which can make large changes on demand.
INLINE CSS- Here, the CSS code is in the line it is to be applied on. Quick, easy, and compact, with good readability - it's more for one-off pieces rather than an entire page, but it can take priority over the other css formats. Also since it's inline, you don't have any extra files to deal with, and you don't have to tweak an internal css in your header tag either. It's also pretty quick, and great for testing! However, it's going to get tiring if you have inline css on every element, and the priority of inline means that it can overwrite styles set by internal and external css. At that point, use a different method unless you have a good reason.
The text is now blue, and looks indented. Neat.
The text is now blue, and looks indented. Neat.
An Internal style sheet means the code is stored in the header section of the site. This is much better than inline because any CSS used within the page will inherit the formatting, Like making all the text red, or making every single letter link to the hitchhiker's guide to the galaxy. Internal is useful as it allows people to test the site’s css quickly and effectively. It also means that, unlike inline, you don’t need to add css to every single element. Mind your loading times though, as internal CSS can slow you down to the pace of a snail in treacle if not careful. It can also make the websites file size bigger, which will then also contribute to wondering if you need to upgrade your internet plan for the 3rd time this month.
An external Style sheet is when the css code is stored in another file, which can then be loaded into the html file with this magic line:
See? The External file is then set up almost identically to how the internal one looks, but without any html. After all ,they aren’t the same thing. An external style sheet can be written in any editor program. The file should not contain HTML tags and should be saved with a .CSS extension. Yes, it does save space, and it also means a cleaner code in general, but External is not really needed for small, single page things.
