Members $16 Public $20
Ready to apply the design framework you learned in Introduction to Localscapes? This course will teach you how to apply the method correctly to ensure you achieve all the benefits a Localscape provides. We'll cover the five section steps in detail including landscape layout, irrigation basics, planting, and maintenance.
SATURDAY, AUGUST 1
1-4PM
Members $50 Public $54
Creating a good landscape plan is one of the most important steps to achieving a beautiful and functional landscape. If you’ve taken Localscapes University but want extra help laying out your design, this workshop will get your ideas onto paper. We’ll walk you through a guided design process that covers the elements of a Localscape and the basics of planting bed design without getting into the details like selecting individual plants. Each attendee should leave with a basic Localscapes design drawn to-scale.


Starting a Translator
We will write a translator for Wink Light Bulbs. If you want to look at the end result, you can find it in the translators repo. Here we will code it step by step.
Everything we are doing here applies to other hardware as well, but Wink has an easy to use API that we will use in our translator. Here's what you need to follow along:
Armed with this information and setup, let's write the translator. We provide a handy yeoman starter that scaffolds out a translator for you. You can read more about yeoman at yeoman.io.
First, install Yeoman and generator-opent2t using npm. Both prefer a global install.
$ npm install --global yo
$ npm install --global generator-opent2t
Next, just use the generator to start your new translator. Use the 'r' argument to provider the cloned translators repository.
$ yo opent2t -r translators
The generator will ask you some questions, and stub out some code based on your answers. You can read more about
the generator, and look at the code, at https://github.com/openT2T/generator-opent2t.
The generated files will look very familiar to you since they are essentially the same as the Test Light Translator with minor differences:
The Manifest.xml file references the "Wink Hub" onboarding module. You can go check it out in the onboarding repo, but the interesting part is that its success signal returns an access token and a device id. That's all we need to talk to devices in the Wink service. We do need to tell onboarding about what kind of Wink device we are trying to set up, so that it can filter down to light bulbs only. We do that by updating the generated manifest to add the following parameters:
<onboarding id="org.OpenT2T.Onboarding.WinkHub">
<arg name="name" value="Wink Light Bulb" />
<!-- when Wink devices are enumerated, only devices that have this id key are shown -->
<arg name="idKeyFilter" value="light_bulb_id" />
</onboarding>
You now have the starting point of your translator. You should move the generated files, with edits above, to the final place where you want to commit your translator. Look at the directory structure of the translators repo for guidance, for example all translators that implement a schema schema need to be in the directory corresponding to that schema.

Question
Reverse digits of an integer.
Example1: x = 123, return 321
Example2: x = -123, return -321
Here are some good questions to ask before coding. Bonus points for you if you have already thought through this!
If the integer's last digit is 0, what should the output be? ie, cases such as 10, 100.
Did you notice that the reversed integer might overflow? Assume the input is a 32-bit integer, then the reverse of<PHONE_NUMBER> overflows. How should you handle such cases?
Throw an exception? Good, but what if throwing an exception is not an option? You would then have to re-design the function (ie, add an extra parameter).

Analysis
There’re 2 points that are tricky.
First, overflow issue. Look at the following overflow case for Java int:
+300,000,000 * 10 returns -1294967296
+600,000,000 * 10 returns +1705032704
-300,000,000 * 10 returns +1294967296
-600,000,000 * 10 returns -1705032704
note that max integer is 2,147,483,647
We can observe that if overflow happens, the result is definitely wrong. The result can be either positive or negative.
So, from just +/- sign of the result, we can’t identify an overflow (then how to solve this problem??).
Another interesting thing to note: we actually do not need to handle negative sign. The sign can be preserved during the conversion. Read this post for more.
Without considering overflow, the following code can (almost) work fine:
public int reverse2(int x) {
int reverse = 0;
while (x != 0) {
reverse = reverse * 10 + x % 10;
x /= 10;
}
return reverse;
}
Solution
Two solutions: 1. use long data type. 2. check if ret > 214748364 or ret < –214748364 before multiplying by 10.
My code
First, using long type to avoid overflow.
public class Solution {
public int reverse(int x) {
int sign = 1;
long abs = x;
long rev = 0;
if (x < 0) {
sign = -1;
abs = 0 - abs;
}
// now remove numbers from abs one by one
// and put these numbers into rev
while (abs != 0) {
rev *= 10;
rev += abs % 10;
abs /= 10;
}
if (rev > Integer.MAX_VALUE) {
return 0;
} else {
return sign * (int) rev;
}
}
}
Second, do boundary check in every step. Suggested by Leetcode official book.
Note that max integer is 2,147,483,647
public class Solution {
public int reverse(int x) {
int ret = 0;
while (x != 0) {
// handle overflow/underflow
if (Math.abs(ret) > 214748364) {
return 0;
}
ret = ret * 10 + x % 10;
x /= 10;
}
return ret;
}
}


When you are coding in a team enviroment it's good to have the subversion properties in your files, that way any other developer can see quickly who made the last changes and when.
You can add the following lines at the bottom of your code:
//—————————————————————————–
// REVISION HISTORY
// $LastChangedDate: $
// $Revision: $
// $LastChangedBy: $
// $Id: $
//—————————————————————————–
And when you perform your svn commit will be automatically populated something like this:
//—————————————————————————–
// REVISION HISTORY
// $LastChangedDate: 2012-02-11 18:24:39 -0500 (Sat, 11 Feb 2012) $
// $Revision: 61 $
// $LastChangedBy: adriansky $
// $Id: Heap.java 61 2012-02-11 23:24:39Z adriansky $
//—————————————————————————–
Also you need to set the SVN properties for that file. The Properties that you need are the following:
- svn:eol-style —> LF
- svn:keywords —> LastChangedDate Revision LastChangedBy Id
If you are using Eclipse you can edit it following this steps:
- right click file you want to add svn properties
- Menu team > set properties (image bellow)
- Select the Property name from the combobox (image bellow)
- Add the text property in the text box (image bellow)
- You can also use files to avoid all the typing every time. right click and 'save as…' to <svn-keywords> and <svn-eol-property>.
- Commit and you are all set.

Doctors say ailing Assange needs medical care in hospital
LONDON (AP) - More than 60 doctors have written to British authorities asserting that WikiLeaks founder Julian Assange urgently needs medical treatment at a university hospital.
The doctors said in a letter published Monday that Assange suffers from psychological problems including depression as well as dental issues and a serious shoulder ailment.
Assange is in Belmarsh Prison on the outskirts of London in advance of an extradition hearing set for February. He is sought by the U.S. on espionage charges relating to his WikiLeaks work.
The letter was sent to Home Secretary Priti Patel.
Dr. Lissa Johnson of Australia said an independent medical assessment is needed to determine if Assange is “medically fit” to face legal proceedings.
The letter was distributed by WikiLeaks.

After three and a half years at The Open Planning Project, my time there is done.
For a while TOPP has been trying to find itself, to determine what it is that it can do best, and how to do that. I think TOPP has finally started really figuring that out, focusing on civic participation, revisiting "planning", and though it’s not fully developed there seems to be a strong potential for TOPP to serve as a point of collaboration for other more ad hoc open source government efforts: government workers and volunteers can provide substantial and well-informed development efforts, but the long-term shepherding of a project is difficult, and TOPP has the potential to provide that kind of long-term neutral guidance. At the same time, communities of people have been developing around these issues; people have gotten past simply calling for government to be inclusive or transparent and have started to do the real work of making that happen.
But… unfortunately I won’t be able to figure out their next steps with them. Mark Gorton has been very generous in his support of TOPP, and helped us get started. But while he has been patient, and even at times seemingly immune from the economic trends… well, he’s not immune, and he has had to cut back his support for TOPP before we were able to become self-sufficient. And so there have been layoffs, myself among them.
I suspect what I’ll do next will have a very different focus. This feels a bit weird, a kind of lost identity. Overall I’m feeling pretty optimistic about finding something new and interesting to do, but I’m still a bit melancholy about leaving things behind. That TOPP and the people I’ve worked with are far away in New York makes it feel like more of a loss because I don’t know when I’ll be back next. But onward and upward! Now to find out what is next…
No related posts.
On a related note, I guess I’ll be renaming toppcloud, as I’ll be continuing the development separately from TOPP. And “cloud” is only maybe 15% of what toppcloud is anyway, so it’s a double-misnomer. Name ideas?
I’ve been thinking that “cloudtop” might be a much nicer name, and much more whimsy, before anything employment might have suggested a name change.
If you’re looking for a new name and need a domain for it, you can try a tool that I built: [shameless plug](http://www.nxdom.com/?left=cloud “NXdom”). For example, the following names were all available when I checked: discloud.com, alticloud.com, sturdycloud.com, cloudwheel.com, cloudberg.com, cloudcoil.com, as well as .net .org etc. for each, and hundreds of other short readable domain names that start or end with cloud. Hope this helps, and good luck for your future after TOPP.
Cloud Engine?
Megacloud, Nucloud, WayCloud, CloudSquared, CloudControl, Cumulo, UberCloud, the possibilities abound. Personally I like Cumulo. ~G~
nullifi (domain is available)
Unfortunately many cool names containing ‘cloud’ are already taken in terms of projects, tools or companies using them. How about cloud2go?
Well… the concept of “cloud” maybe could be extended. Aspirator? Something about a drop in the ocean…
How about ‘Cirrus’, as a literal interpretation of ‘top cloud’?
There are lots of other things called ‘Cirrus’, but not software AFAICS.
I like it. And Cirrus is the most whimsical of all cloud names.
Sorry to hear this news, Ian. Feel free to give me a call if you want a sympathetic ear.
Bad news, I’d like to see TOPP inspiring other communities. Especially in countries where big companies are still in a very strong position and open source solutions discarded because it doesn’t cost enough money (maybe).
Cheers from MS-Switzerland[¹](http://www.eweekeurope.co.uk/news/red-hat-sues-switzerland-over-microsoft-monopoly-965)
I’m really sorry to hear that. I know you enjoyed your time with them. That said I know you will get a ton of proposals and you will find something that makes you enjoy things, perhaps even more than topp?
Now that’s interesting. I assumed toppcloud was from “top” as in “on top of the cloud” with the double p for fun and profit.
PS: I’m terrible with names but anywhere it goes i’ll follow toppcloud. Perhaps go with something more technical? it is still a very geeky package. Maybe along the lines of venv, pip, I like the recursive acronym thing. Maybe something that way.
Sorry, man. You’ll find something, of course.
Sorry about that… But I am not worried about you getting hundreds of proposals :)
For the renaming, what about a touch of french ;) “JoliNuage” which means “beautiful cloud”. Now I don’t know how that sounds in English..
How about “reinmaker”? It sounds like “rain maker”, which is a result of seeding a cloud (get it?). And it makes reins, as in the item used to direct an animal, as you would steer a horse.
Names:
Firehose
Upchuck
Tossup
Skyshot
Wooshie
Flying Circus
Dr Flying
Unexpectedly
Baloonz
Up Ploy
Space Elevator
Space Monkey
Rocket Booster
I like where you’re going with these names. “Tossup” would sound a lot better if you hadn’t put “upchuck” just before it in the list ;)
Good Luck Ian! As for the toppcloud rename, how about just changing TOPP to “top”, e.g. topcloud: the “The top tool for one click deployment of Python web applications to the cloud” ;-) (Who cares if it’s not just for the cloud, this is marketing! ;-))
Yes, it’s always scary to go through something like this, but as Tarek wrote, I am not too worried about you. It is sad about TOPP but it was bound to happen as TOPP was always more interested in its mission than in its business model. It is good news for someone there… I would’ve hired you right now if I could. Maybe I (we would… There’s a bunch of very interesting initiatives we’re taking part in right now. If the budgets roll in I think I will not be the only one at ShiftSpace to want to have your fingers coding for us.
You can check out the Knight News Challenge application we submitted. It’s called NewsShift and I think you will find it very relevant to the things you’ve been working on lately.
Let’s touch base sometime soon. Excited to see what you’ll be up to next…

Dat Protocol
DEP-0008: Multi-Writer
Title: DEP-0008: Multi-Writer
Short Name: 0008-multiwriter
Type: Standard
Status: Draft (as of 2018-07-06)
Github PR: Draft
Authors: Bryan Newbold, Stephen Whitmore, Mathias Buus
Summary
Multi-Writer is a set of schema, API, and feature extensions to allow multiple agents (users, devices, or software) to write to the same hyperdb database. By building on top of this abstraction layer, future versions of hyperdrive and Dat will gain these features.
Mechanisms for distributed consistency and granting trust are specified here; the need for merge conflict algorithms and secure key distribution are mentioned but specific solutions are not specified.
This DEP forms the second half of the hyperdb specification; the first half covered only the key/value database aspects of hyperdb.
Motivation
The current hypercore/Dat ecosystem currently lacks solutions for two fundamental use cases:
- individual users should be able to modify distributed archives under their control from multiple devices, at a minimum to prevent loss of control of content if a single device (containing secret keys) is lost
- contributions from and collaboration between multiple users on a single archive or database should be possible, with appropriate trust and access control semantics
Access to a single secret key is currently required to make any change to a hypercore feed, and it is broadly considered best practice not to distribute secret keys between multiple users or multiple devices. In fact, the current hypercore implementation has no mechanism to resolve disputes or recover if multiple agents used the same secret key to append to the same feed.
Solutions to these two use cases are seen as essential for many current and future Dat ecosystem applications.
Concepts, Behavior, and Usage
The multi-writer features of hyperdb are implemented by storing and replicating the contributions of each writer in a separate hypercore feed. This specification concerns itself with the details of how changes from multiple feeds (which may be written and replicated concurrently or asynchronously) are securely combined to present a unified key/value interface.
The following related concerns are explicitly left to application developers to design and implement:
- secure key distribution and authentication (eg, if a friend should be given write access to a hyperdb database, how is that friend's feed key found and verified?)
- merge conflict resolution (using the provided API), potentially using application-layer semantics
Before we go any further, a few definitions:
Feed: A hypercore feed: an append-only log of Entries, which can be arbitrary data blobs.
Database: in this context, a Hyperdb key/value database. Built from several Feeds (two Feeds per Writer).
Writer: a user (or user controlled device or software agent) that has a distinct feed with a public/private key pair, and thus the ability to append hypercore entries and "write" changes to their version of the database.
Original Writer: the writer who created a given hyperdb database in the form of the Original Feed. The public key of the original feed is the one used to reference the database as a collection of feeds (eg, for the purpose of discovery).
At a high level, multi-writer hyperdb works by having existing authorized writers (starting with the original writer) include authorization of new writers by appending metadata to their own feed which points to the new feeds (by public key). Each entry in each writer's feed contains "clock" metadata that records the known state of the entire database (all writers) seen from the perspective of that writer at the time they created the entry, in the form of "clock" version pointers. This metadata (a "vector clock") can be used by other writers to resolve (or at least identify) conflicting content in the database. The technical term for this type of system is a "Conflict-free replicated data type" (CRDT), and specifically an "Operation-based" (as opposed to "State-based") CRDT.
Core API
A "node" is a data structure representing a database entry, including the
key
, value
, and feed that the entry is committed to.
db.get(key)
(as described in the hyperdb DEP)
returns an array of nodes. If it is unambiguous what the consistent state of a
key is, the array will have only that one value. If there is a conflict
(ambiguity), multiple nodes will be returned. If a key has unambiguously been
removed from the database, a "null" or empty datatype is returned. If one
branch of a conflict has a deletion (but at least one of the others does not),
a node with the deleted
flag will be returned; note that such "tombstone"
nodes can still have a value
field, which may contain application-specific
metadata (such as a self-reported timestamp), which may help resolve the
conflict.
If multiple nodes are returned from a get
, the writer should attempt to merge
the values (or chose one over the other) and write the result to the database
with db.put(key, value)
. Client libraries can make this process more
ergonomic by accepting a helper function to select between multiple nodes.
Libraries can also offer an option to either directly return the value of a
single node (instead of the node itself), or raise an error; this is likely to
be more ergonomic for applications which do not intend to support multiple
writers per database.
db.authorize(key)
will write metadata to the local feed authorizing the new
feed (corresponding to key
) to be included in the database. Once authorized,
a feed may further authorize additional feeds (recursively).
db.authorized(key)
(returning a boolean) indicates whether the given key
is
an authorized writer to the hyperdb database.
At the time of this DEP there is no mechanism for revoking authorization.
Scaling
There is some overhead associated with each "writer" added to the feed, impacting the number of files on disk, memory use, and the computational cost of some lookup operations. The design should easily accommodate dozens of writers, and should scale to 1,000 writers without too much additional overhead. Note that a large number of writers also implies a larger number and rate of append operations, and additional network connections, which may cause scaling issues on their own. More real-world experience and benchmarking is needed in this area.
Implementation Details
The complete protobuf schemas for the hyperdb "Entry" and "InflatedEntry" message types (as specified in the hyperdb DEP) are:
message Entry {
required string key = 1;
optional bytes value = 2;
optional bool deleted = 3;
required bytes trie = 4;
repeated uint64 clock = 5;
optional uint64 inflate = 6;
}
message InflatedEntry {
message Feed {
required bytes key = 1;
}
required string key = 1;
optional bytes value = 2;
optional bool deleted = 3;
required bytes trie = 4;
repeated uint64 clock = 5;
optional uint64 inflate = 6;
repeated Feed feeds = 7;
optional bytes contentFeed = 8;
}
The fields of interest for multi-writer are:
clock
: a "vector clock" to record observed state at the time of writing the entry. Included in every Entry and InflatedEntry.inflate
: a back-pointer to the entry index of the most recent InflatedEntry (containing a feed metadata change). Included in every Entry and InflatedEntry. Should not be included for the very first entry in a feed (which is an InflatedEntry).feeds
: list of public keys for each writer's feed. Only included in InflatedEntry, and only when feeds have changed. Does include a self-reference to the current (local) Feed's key, always as the first element.
When serialized on disk in a SLEEP directory:
source/
: the original feed, as created or cloned by this writerlocal/
: if "local" feed is different from "source", it goes herepeers/<discover-key>/
: all other writers' feed go under this directory (the discovery key is lower-case hex-encoded)content/<discovery-key>/
: if a higher-level protocol is being used that uses multiple linked hypercore feeds (eg, hyperdrive), the linked "content" feeds all go under this directory
Feeds and Vector Clocks
At any point in time, each writer has a potentially unique view of the "current" state of the database as a whole; this is the nature of real-world distributed systems. For example, a given write might have the most recent appends from one peer (eg, only seconds old), but be missing much older appends from another (eg, days or weeks out of date). By having each writer include metadata about their perceived state of the system as a whole in operations to their Feed, all writers are able to collectively converge on an "eventually consistent" picture of the database as whole (this process will be described in the next section).
A writer's "current known state" of the database consists of the set of active Feeds, and for each the most recent entry sequence number ("version"). This state can be serialized as an array of integers, referred to as a vector clock.
Each put()
operation on the database appends a node to the writer's local
feed, and contains the writer's vector clock as observed at that time.
InflatedEntry
nodes also contain a list of all known authorized Feeds;
inflated nodes only need to be written when the Feed list changes.  Elements of a vector clock
are ordered by the Feed list from the corresponding Inflated entry.
By convention, the order of Feed lists is to start with the writer's local feed first, then proceed by the order in which Feeds were discovered. Note that this ordering is not consistent across writers, only within the same feed.
As an example, if a node (non-inflated entry) had a vector clock of [1, 3,
6]
, that would mean:
- when this node was written, the largest seq # in the writer's local fed was 1
- when this node was written, the largest seq # in the second known feed was 3
- when this node was written, the largest seq # in the third known feed was 6
Multi-Feed Aware hyperdb
The hyperdb DEP specifies the procedures for lookup (get()
)
and append (put()
) operations to the database, as well as binary encoding
schemes for entry messages.
Note that the trie encoding specifies pointers in a (feed, entry)
pair
format. The feed
integer is an index into the most recent Feed list (found in
the most recent inflated entry; see the last section). When working with a
multi-writer hyperdb database, simply look up entries in the appropriate feed,
instead of only looking in the current feed. The next section ("Consistent
History") describes which entry (or entries) to start with instead of simply
assuming the most recent entry from the local feed.
Consistent History
The set of all appended nodes in all feeds of a hyperdb, and all the vector clock pointers between them, forms a "directed acyclic graph" (DAG). Any node which does not have another node pointing to it is called a "head" (this terminology is similar to that used in git). At any point in time, an observed copy of a database has one or more heads, each representing the top of a tree-like graph. In the trivial case of a non-multi-writer hyperdb, there is always only a single head: the most recent entry in the local feed. Just after appending to the local feed, there is also always a single head, because that node's vector clock will reference all know most recent entries from other feeds. It is only when nodes are appended by separate writers who did not know of the others' concurrent action (and then these changes are replicated) that there are multiple heads.
When operating on the database (eg, executing a get()
operation), all heads
must be considered. The lookup procedure documented in the hyperdb
DEP must be repeated for each head, and nodes returned
representing the set of all unique values.
The situation where a get()
operation multiple heads returns different values
for the same key is called a "conflict" and requires a "merge" to resolve. Some
writer (either a human being or application-layer code) must decide on the
correct value for the key and write that value as a new entry (with a vector
clock that includes the previous heads). The procedure for choosing the best
value to use in a given conflict is sometimes easy to determine, but is
impossible to determine algorithmically in the general case. See the "Usage"
section for more details.
Examples
Every hyperdb hypercore feed starts with a protocol header (of type
HypercoreHeader
) at entry index 0, as specified in DEP-0007. Feed entry
indexes (aka, sequence numbers), are zero-indexed. With the header message at
index 0, hyperdb entries start at index 1.
Let's say Alice starts a new hyperdb and writes two key/value entries to it:
// Operations
Alice: db.put('/foo/bar', 'baz')
Alice: db.put('/foo/2', '{"json":3}')
// Alice's Feed
0 (HypercoreHeader, protocol=hyperdb)
1 (key='/foo/bar', value='baz',
vector_clock=[1], inflated=null, feeds=['a11ce...']) (InflatedEntry)
2 (key='/foo/2', value='{"json":3}',
vector_clock=[1], inflated=0)
// Graph
Alice: 1 <--- 2
The vector clock at seq=2
points back to seq=1
.
Next Alice authorizes Bob to write to the database. Internally, this means Alice writes an Inflated entry to her feed that contains Bob's Feed (identified by his public key) in her feed list.
// Operations
Alice: db.authorize('b0b123...')
// Alice's Feed
0 (HypercoreHeader, protocol=hyperdb)
1 (key='/foo/bar', value='baz',
vector_clock=[1], inflated=null, feeds=['a11ce...']) (InflatedEntry)
2 (key='/foo/2', value='{"json":3}',
vector_clock=[1], inflated=1) (Entry)
3 (key=null, value=null,
vector_clock=[2], inflated=1, feeds=['a11ce...', 'b0b123...']) (InflatedEntry)
// Graph
Alice: 1 <--- 2 <--- 3
Bob writes a value to his feed, and then Alice and Bob sync. The result is:
// Operations
Bob: db.put('/a/b', '12)
// Alice's Feed
0 (HypercoreHeader, protocol=hyperdb)
1 (key='/foo/bar', value='baz',
vector_clock=[1], inflated=null, feeds=['a11ce...']) (InflatedEntry)
2 (key='/foo/2', value='{"json":3}',
vector_clock=[1], inflated=1) (Entry)
3 (key=null, value=null,
vector_clock=[2], inflated=1, feeds=['a11ce...', 'b0b123...']) (InflatedEntry)
// Bob's Feed
0 (HypercoreHeader, protocol=hyperdb)
1 (key='/a/b', value='12',
vector_clock=[0], inflated=null, feeds=['b0b123...']) (InflatedEntry))
// Graph
Alice: 1 <--- 2 <--- 3
Bob : 1
Notice that none of Alice's entries refer to Bob's, and vice versa. Neither has
written any entries to their feeds since the two became aware of each other.
Right now there are two "heads" of the graph: Alice's feed at seq 3, and Bob's
feed at seq 1. Any get()
operations would need to descend from both heads,
though in this situation there would be no conflicts as the keys in the two
feeds are disjoint.
Next, Alice writes a new value, and her latest entry will refer to Bob's:
// Operations
Alice: db.put('/foo/hup', 'beep')
// Alice's Feed
0 (HypercoreHeader, protocol=hyperdb)
1 (key='/foo/bar', value='baz',
vector_clock=[0], inflated=null, feeds=['a11ce...']) (InflatedEntry)
2 (key='/foo/2', value='{"json":3}',
vector_clock=[0], inflated=0) (Entry)
3 (key=null, value=null,
vector_clock=[1, null], inflated=0, feeds=['a11ce...', 'b0b123...']) (InflatedEntry)
4 (key='/foo/hup', value='beep',
vector_clock=[2,0], inflated=2) (Entry)
// Bob's Feed
0 (HypercoreHeader, protocol=hyperdb)
1 (key='/a/b', value='12',
vector_clock=[0], inflated=null, feeds=['b0b123...']) (InflatedEntry))
// Graph
Alice: 1 <--- 2 <--- 3 <--/ 4
Bob : 1 <-------------------/
Alice's latest feed entry now points to Bob's latest feed entry, and there is
only one "head" in the database. This means that any get()
operations only
need to run once, starting at seq=4
in Alice's feed.
Security and Privacy Concerns
As noted above, there is no existing mechanism for removing authorization for a feed once added, and an authorized feed may recursively authorize additional feeds. There is also no mechanism to restrict the scope of an authorized feed's actions (eg, limit to only a specific path prefix). This leaves application designers and users with few tools to control trust or access ("all or nothing"). Care must be taken in particular if self-mutating software is being distributed via hyperdb, or when action may be taken automatically based on the most recent content of a database (eg, bots or even third-party tools may publish publicly, or even take real-world action like controlling an electrical relay).
There is no mechanism to remove malicious history (or any history for that matter); if an authorized (but hostile) writer appends a huge number of key operations (bloating hyperdb metadata size), or posts offensive or illegal content to a database, there is no way to permanently remove the data without creating an new database.
The read semantics of hyperdb are unchanged from hypercore: an actor does not need to be "authorized" (for writing) to read the full history of a database, they only need the public key.
As noted in other DEPs, a malicious writer can potentially execute a denial of service (DoS) attack by appending hyperdb entries that for a cyclic loop of references.
Drawbacks
Mutli-writer capability incurs a non-trivial increase in library, application,
and user experience complexity. For many applications, collaboration is an
essential feature, and the complexity is easily justified. To minimize
complexity for applications which do not need multi-writer features,
implementation authors should consider configuration modes which hide the
complexity of unused features. For example, by having an option to returning a
single node for a get()
(and throw an error if there is a conflict), or a
flag to throw an error if a database unexpectedly contains more than a single
feed.
Two tasks (conflict merges and secure key distribution) are left to application developers. Both of these are Hard Problems. The current design mitigates the former by reducing the number of merge conflicts that need to be handled by an application (aka, only the non-trivial ones need to be handled), and implementation authors are encouraged to provide an ergonomic API for writing conflict resolvers. The second problem (secure key distribution) is out of scope for this DEP. It is hoped that at least one pattern or library will emerge from the Dat ecosystem such that each application author doesn't need to invent a solution from scratch.
Rationale and alternatives
Design goals for hyperdb (including the multi-writer feature) included:
- ability to execute operations (get, put) with a sparse (partial) replication of the database, using as few additional network requests as possible
- minimal on-disk and on-wire overhead
- implemented on top of an append-only log (to build on top of hypercore)
If a solution for core use cases like collaboration and multi-device synchronization is not provided at a low level (as this DEP provides), each application will need to invent a solution at a higher level, incurring duplicated effort and a higher risk of bugs.
As an alternative to CRDTs, Operational Transformation (OT) has a reputation for being more difficult to understand and implement.
Unresolved questions
What is the actual on-disk layout (folder structure), if not what is documented here?
The local feed's sequence number could skipped from vector clocks, because it's implied by the sequence number of the hypercore entry itself. Same with the key in the feed list (for inflated entries). In both cases, the redundant data is retained for simplicity.
If there are multiple heads, but they all return the same value
for a get()
operation, how is it decided which node
will be returned? AKA, values are the
same, but node metadata might not be (order of vector clock, etc).
Suspect that some details are off in the example: shouldn't the InflatedEntry authorizing a new feed include a vector clock reference to a specific seq in that feed? Should new local (not yet authorized) feeds reference their source in an initial InflatedEntry (eg, Bob at seq=0)? Should the first InflatedEntry in a feed point to itself in it's vector clock?
Changelog

Police get three days’ custody of gang-rape accused
by Staff ReporterThe All Women Police Station (West) on Monday got three days custody of P. Manikandan, 30, suspected to be the main accused in the gang-rape of a class XI girl in Coimbatore.
The Mahila Court-cum-Special Court for Children here granted police the custody of the accused who hails from Seeranaickenpalayam where he and five others allegedly gang-raped the minor girl outside a park on November 26. The men had also allegedly assaulted her male friend and photographed the acts.
A senior police officer said that Manikandan will be interrogated in custody to collect more details of the incident as he was never questioned.
While five other accused in the case namely, T. Rahul, 21, R. Prakash, 22, S. Karthikeyan, 28, S. Narayanamurthy, 30, R. Karthik, 24, were arrested by the police, Manikandan surrendered before the Mahila Court on December 3. Hence, the investigating team had not questioned him.
The police suspect that Manikandan played prime role in the crime.
The police will also examine his mobile phone to check presence of photo or video of the crime as the victim had told police that the accused photographed the acts.

Skyr is an Icelandic yoghurt that is starting to appear in our supermarkets. It is good with chicken because it takes other flavours well and helps the meat get lovely and tender.
To make the marinated chicken, cut down the centre of each breast lengthways, being careful not to cut all the way through.
Put the skyr or yoghurt, oil, parsley, ginger, lemon juice and some salt and pepper in a food processor and blend until smooth.
Put the butterflied chicken breasts in a freezer bag and add the marinade, mixing well to cover the chicken. Seal and chill in the fridge.
Meanwhile, to make the salad, boil the potatoes for 15 minutes, or until tender, and drain. Cover with cold water and set aside to cool.
To make the dressing, whisk together the skyr or yoghurt, oil, mustard, 1 teaspoon of the vinegar and ½ teaspoon of the honey, along with a pinch of salt and pepper. If the mixture is a little thick, add a tablespoon of water at a time until the desired consistency is reached. Stir in the chives and adjust the seasoning, or add a little more vinegar and/or honey if needed.
Halve the cooled potatoes and toss with a little of the dressing in a bowl, until coated. Put the courgette and carrot in a serving bowl and add dressed potatoes.
Heat a dash of oil in a large, heavy-based frying pan over a medium–high heat. Shake off the excess marinade and cook the chicken, opened out, for 4 minutes on either side, or until cooked through. Reduce the heat if it is browning too much.
Slice the chicken and place on top of the salad. Drizzle over the rest of the dressing, garnish with more chopped chives and serve.

If you have seen a movie or show with a journalist in it, chances are they did some pretty questionable things. They probably came unprepared for their job or breached basic journalism ethics, like fabricating a whole article. But if you’ve ever seen media with a female journalist, they’ve probably slept with their source, right?
Well, for those who believe everything they see on TV, that doesn’t really happen. The Camille Preakers and Shauna Malwae-Tweeps of the world are far and few between, but that doesn’t stop Hollywood from portraying the profession as anything less than sleazy.
Journalism is probably one profession that few people understand. There is a lot that goes into crafting an article to inform the audience and capture the attention of its readers. Research is conducted, interviews are scheduled and facts are checked. Editors make the article better, and then it’s published in its respective mediums, whether that be print or online.
Film and television don’t show all of that though. Writers and directors get a little too personal. They make the journalists these complex characters that we latch onto, but those characters make unethical decisions that almost all journalists would condemn.
This conversation came to the forefront once again with last year’s Sharp Objects on HBO. Amy Adams’ character Camille Preaker goes back to her hometown to cover the murders of children. In the show, she does most everything right. She is persistent, consults her editor and tells a truthful tale. Sure, she drinks, and she insensitively sat toward the front of a funeral service even though she was reporting. It looked like female journalists were going to get a rare positive representation — until she slept with not only one, but two of her sources.
When people start seeing those representations repeatedly, people start believing that might actually be accurate. As creators make more unethical journalists, everyday consumers will believe that to be fact. Representing the media in a more positive way is important in this era of fake news. The filmmaker’s job is not to create an accurate character, but it becomes a problem when that portrayal seeps into the mindset of its viewers.
Not all journalism films paint the media in a bad light. Take the 2015 Best Picture winner Spotlight. It showed an accurate representation of watchdog journalism, and did so in a respectful manner. In that film though, the journalists were seen as heroes.
There are two polar opposites with journalists in film and TV: They either uncover injustice (also known as superhero journalism) or they break every ethics rule in the book. There is no in between. It would be great to get a character who is a journalist who just does their job. That might not be as exciting, but it would be, as journalists say, more fair.

The recent release of the LiveDashboard library allows us to visualize our application metrics, performance and behavior in real-time. In this post, we’ll add LiveDashboard to our Phoenix app, examine the out-of-the-box features and take a look under the hood to understand how LiveDashboard hooks into Telemetry events in order to visualize them.
The App
We’ll be working with the Phoenix app we set up for our Telemetry series of blog posts, Quantum. The Quantum app doesn’t do much–it really just exists to be measured. In this post, we’ll set up a Telemetry supervisor that implements a set of metrics definitions for Telemetry events. The metrics we’ll define match up to some out-of-the-box Telemetry events emitted by Phoenix and Ecto. For a deeper dive on Telemetry events, check out our series of posts on Instrumenting Phoenix with Telemetry. Upcoming posts in this series take a closer look at the out-of-the-box Telemetry events offered by Phoenix and Ecto, walkthrough how to add our own Telemetry events and more.
The Code
The final code for this walkthrough can be found here.
Adding LiveDashboard
First, we’ll add the LiveDashboard dependency to our Phoenix app:
# mix.exs
def deps do
[
{:phoenix_live_dashboard, "~> 0.1"}
]
end
Next up, we’ll ensure LiveView is configured:
# config/config.exs
config :quantum, QuantumWeb.Endpoint,
live_view: [signing_salt: "SECRET_SALT"]
Then, we’ll ensure the LiveView socket is declared in our app’s Endpoint
:
# lib/quantum_web/endpoint.ex
socket "/live", Phoenix.LiveView.Socket
Lastly, we’ll set up request forwarding from the /dashboard
endpoint to the LiveDashboard in our router:
use MyAppWeb, :router
import Phoenix.LiveDashboard.Router
...
if Mix.env() == :dev do
scope "/" do
pipe_through :browser
live_dashboard "/dashboard"
end
end
And that’s it! If we run mix deps.get
and then mix phx.server
, we’ll see our LiveDashboard with its out-of-the-box monitoring visualizations.
LiveDashboard Out-Of-The-Box
Home
There are a number of monitoring features that LiveView displays for us out-of-the-box.
On the Home
page, we can see system information like our Erlang/OTP version, Phoenix version and Elixir version. We also see some info about the number of ports, processes and atoms our app is responsible for.
Processes
The Processes
page allows us to introspect on the processes running in our app. We can see helpful info like how much memory each process account for and even which function a given process is currently executing. Inspecting a given process, we see further info including its status, initial function and stacktrace.
Ports
The Ports
page visualizes the ports (responsible for application I/O) exposed by our application.
Inspecting a given port, we can see the which process is responsible for exposing the port and managing input/output over that port.
Sockets
The Sockets
page exposes information about all of the sockets currently managed by the application. Sockets in our Phoenix app are responsible for all UDP/TCP traffic. Here, we even see the socket connection responsible for listening on port :4000
.
ETS
The last out-of-the-box page that the LiveDashboard offers us is the ETS
page. ETS (Erlang Term Storage) is our in-memory storage. We can even se the entry for the Telemetry handler table.
LiveDashboard Metrics
Establishing Metrics
There are two LiveDashboard features that we have to do a little bit of work to enable. We’ll start with LiveDashboard Metrics, which leverages the telemetry_metrics
library.
First, we’ll add telemetry_metrics
to our application’s dependencies:
# mix.exs
{:telemetry_metrics, "~> 0.4"},
And run mix deps.get
The Telemetry.Metrics
library provides an interface for casting Telemetry events as metrics. We’ll take a closer look at this library in a later blog post, and just focus on a high-level understanding for now.
Now that we’ve installed the library, we’re ready to define our Telemetry supervisor. The supervisor will implement a metrics/0
function that declares the set of Telemetry events that we want to handle and specifies which metrics to construct for these events.
# lib/quantum/telemetry.ex
defmodule Quantum.Telemetry do
use Supervisor
import Telemetry.Metrics
def start_link(arg) do
Supervisor.start_link(__MODULE__, arg, name: __MODULE__)
end
def init(_arg) do
Supervisor.init([], strategy: :one_for_one)
end
def metrics do
[
# Erlang VM Metrics - Formats `gauge` metric type
last_value("vm.memory.total", unit: :byte),
last_value("vm.total_run_queue_lengths.total"),
last_value("vm.total_run_queue_lengths.cpu"),
last_value("vm.system_counts.process_count"),
# Database Time Metrics - Formats `timing` metric type
summary(
"quantum.repo.query.total_time",
unit: {:native, :millisecond},
tags: [:source, :command]
),
# Database Count Metrics - Formats `count` metric type
counter(
"quantum.repo.query.count",
tags: [:source, :command]
),
# Phoenix Time Metrics - Formats `timing` metric type
summary(
"phoenix.router_dispatch.stop.duration",
unit: {:native, :millisecond}
),
# Phoenix Count Metrics - Formats `count` metric type
counter(
"phoenix.router_dispatch.stop.count"
),
counter(
"phoenix.error_rendered.count"
)
]
end
end
Here, we’re using the Telemetry.Metrics
’s metrics functions (counter
, summary
and last_value
) to specify which Telemetry events to treat as which kinds of metrics. Each of these functions takes in an argument of a Telemetry event, for example, quantum.repo.query.total_time
. The events listed in our metrics/0
function are all executed by Phoenix or Ecto source code for us, for free.
The metrics/0
function is later passed to a LiveDashboard LiveView. LiveDashboard uses this list of Telemetry events-as-metrics to attach the appropriate handler for each event. For a refresher on how Telemetry events are executed and handled with the help of ETS, check out our intro to Telemetry blog post here.
We’ll revisit how this works in a bit. First, let’s add our new supervisor to our app’s supervision tree:
# lib/quantum/application.ex
children = [
Quantum.Repo,
Quantum.Telemetry,
Quantum.Endpoint,
...
]
Now we’re ready to configure LiveDashboard with our newly defined metrics.
Configuring LiveDashboard Metrics
We’ll add the following option to our live_dashboard
router call.
# lib/quantum_web/router.ex
live_dashboard "/dashboard", metrics: Quantum.Telemetry
Now, if we visit /dashboard
in the browser and click the Metrics
tab we’ll see our metrics:
Let’s take a peek under the hood to better understand how this configuration works.
LiveDashboard Metrics Under the Hood
The live_dashboard
macro contains the following line which routes live /metrics
requests to the Phoenix.LiveDashboard.MetricsLive
LiveView, with a session payload containing the metrics: Quantum.Telemetry
options we passed in:
# live_dashboard/router.ex
live "/:node/metrics", Phoenix.LiveDashboard.MetricsLive, :metrics, opts
When the Phoenix.LiveDashboard.MetricsLive
LiveView starts up, it calls on the Phoenix.LiveDashboard.TelemetryListener.listen/2
function with an argument of the metrics we defined in Quantum.Telemetry
.
The Phoenix.LiveDashboard.TelemetryListener
module is responsible for attaching a set of handlers to Telemetry events by storing the event/handler combos in ETS. The init/1
function of the Phoenix.LiveDashboard.TelemetryListener
iterates over the metrics we defined in Quantum.Telemetry
, and stores each metric’s Telemetry event name in ETS with a handler of its own handle_metrics/4
function.
# live_dashboard/telemetry_listener.ex
def init({parent, metrics}) do
metrics = Enum.with_index(metrics, 0)
metrics_per_event = Enum.group_by(metrics, fn {metric, _} -> metric.event_name end)
for {event_name, metrics} <- metrics_per_event do
id = {__MODULE__, event_name, self()}
:telemetry.attach(id, event_name, &handle_metrics/4, {parent, metrics})
end
{:ok, %{ref: ref, events: Map.keys(metrics_per_event)}}
end
Recall from our earlier post on Telemetry that the :telemetry.attach/4
function stores entries in ETS that map the Telemetry event to the handler. Later, when the given Telemetry event is executed (for example, when Ecto source code executes the "quantum.repo.query.total_time"
event), Telemetry will look up the event with this name in ETS and call the stored handler function, in this case Phoenix.LiveDashboard.TelemetryListener.handle_metrics/4
Taking a look at the Phoenix.LiveDashboard.TelemetryListener.handle_metrics/4
function, we can see that it does some work to format the metric for the event and then sends a message to its parent
–the Phoenix.LiveDashboard.MetricsLive
LiveView.
# live_dashboard/telemetry_listener.ex
def handle_metrics(_event_name, measurements, metadata, {parent, metrics}) do
time = System.system_time(:second)
entries =
for {metric, index} <- metrics do
if measurement = extract_measurement(metric, measurements) do
label = tags_to_label(metric, metadata)
{index, label, measurement, time}
end
end
send(parent, {:telemetry, entries})
end
The Phoenix.LiveDashboard.MetricsLive
LiveView implements a handle_info/2
for this {:telemetry, entries}
event and responds by updating the ChartComponent
, resulting in a UI update.
# live_dashboard/live/metrics_live.ex
def handle_info({:telemetry, entries}, socket) do
for {id, label, measurement, time} <- entries do
data = [{label, measurement, time}]
send_update(ChartComponent, id: id, data: data)
end
{:noreply, socket}
end
Putting It All Together
Let’s review how all of these moving parts connect.
- We define a Telemetry supervisor,
Quantum.Telemetry
, that implements ametrics/0
function. This function is responsible for mapping a set of Telemetry events to various types of metrics. - We pass our Telemetry supervisor,
Quantum.Telemetry
, as an option to our LiveDashboard in the router. - LiveDashboard starts up a LiveView,
Phoenix.LiveDashboard.MetricsLive
, with the metrics we defined inQuantum.Telemetry
. Phoenix.LiveDashboard.MetricsLive
calls onPhoenix.LiveDashboard.TelemetryListener
which stores the Telemetry events-as-metrics we defined inQuantum.Telemetry
in ETS with its ownhandle_metrics/4
handler function.- Later, when one of these Telemetry events is executed, Telemetry calls the stored handler function,
Phoenix.LiveDashboard.TelemetryListener.handle_metrics/4
. - The
handle_metrics/4
function formats the event as the specified metric and sends a message to thePhoenix.LiveDashboard.MetricsLive
LiveView which then updates the UI!
This process if pretty cool, but there’s a lot to unpack here. For a deeper dive on how Telemetry events are stored in ETS, executed and handled, check out this post.
LiveDashboard Request Logging
The last LiveDashboard feature that we’ll set up is RequestLogger. This LiveDashboard features allows us to log all incoming requests in LiveDashboard.
Adding RequestLogger
All we need to do to get this up and running is add the following to our app’s Endpoint
module, right before Plug.RequestId
:
# lib/quantum_web/endpoint.ex
plug Phoenix.LiveDashboard.RequestLogger,
param_key: "request_logger",
cookie_key: "request_logger"
Now we can visit /dashboard
in the browser and click the Request Logger
tab. We’ll click “enable cookie” to enable a cookie that streams request logs. Now we should see the stream of our request logs:
Let’s take a brief look under the hood of LiveDashboard to get a better understanding of how RequestLogger works.
LiveDashboard RequestLogger Under The Hood
The LiveDashboard router mounts a LiveView, Phoenix.LiveDashboard.RequestLoggerLive
:
# live_dashboard/router.ex
live "/:node/request_logger",
Phoenix.LiveDashboard.RequestLoggerLive,
:request_logger,
opts
The RequestLoggerLive
LiveView grabs the main application’s PubSub server from the endpoint and subscribes to a “request logger” topic:
# live_dashboard/live/request_logger_love.ex
def mount(%{"stream" => stream} = params, session, socket) do
%{"request_logger" => {param_key, cookie_key}} = session
if connected?(socket) do
endpoint = socket.endpoint
pubsub_server = endpoint.config(:pubsub_server) || endpoint.__pubsub_server__()
Phoenix.PubSub.subscribe(pubsub_server, Phoenix.LiveDashboard.RequestLogger.topic(stream))
end
socket =
socket
|> assign_defaults(params, session)
|> assign(
stream: stream,
param_key: param_key,
cookie_key: cookie_key,
cookie_enabled: false,
autoscroll_enabled: true,
messages_present: false
)
{:ok, socket, temporary_assigns: [messages: []]}
end
This means that the RequestLoggerLive
LiveView process is subscribed to any events that are broadcast over the “request logger” topic. It implements a handle_info/2
function for {:logger, level, message}
events, and responds by updating the socket and therefore the UI:
# live_dashboard/live/request_logger_live.ex
def handle_info({:logger, level, message}, socket) do
{:noreply, assign(socket, messages: [{message, level}], messages_present: true)}
end
When do {:logger, level, message}
events get broadcast over PubSub to this topic?
LiveDashboard adds a new logging backend to the application when it starts up.
# live_dashboard/application.ex
defmodule Phoenix.LiveDashboard.Application do
@moduledoc false
use Application
def start(_, _) do
Logger.add_backend(Phoenix.LiveDashboard.LoggerPubSubBackend) # HERE!
children = [
{DynamicSupervisor, name: Phoenix.LiveDashboard.DynamicSupervisor, strategy: :one_for_one}
]
Supervisor.start_link(children, strategy: :one_for_one)
end
end
The Phoenix.LiveDashboard.LoggerPubSubBackend
broadcasts the log message to the RequestLogger PubSub topic whenever it receives a log event:
# live_dashboard/logger_pubsub_backend.ex
def handle_event({level, gl, {Logger, msg, ts, metadata}}, {format, keys} = state)
when node(gl) == node() do
with {pubsub, topic} <- metadata[:logger_pubsub_backend] do
metadata = take_metadata(metadata, keys)
formatted = Logger.Formatter.format(format, level, msg, ts, metadata)
Phoenix.PubSub.broadcast(pubsub, topic, {:logger, level, formatted}) # HERE!
end
{:ok, state}
end
And that’s it!
Conclusion
LiveDashboard adds a powerful tool to the Phoenix developer’s toolkit. Now we can easily visualize the instrumentation of our application and monitor its performance and behavior in real-time as we develop. LiveDashboard represents one more entry into the growing pantheon of “developer happiness” tools that is increasingly making Phoenix, and Elixir, such a compelling option for web development.
I hope this feature tour got you excited about LiveDashboard, while our peek under the hood illustrates once again how Elixir language features like ETS and message-passing make it possible to build powerful systems that are still simple and elegant.

Session objects handles the actual queueing of database operations. The primary methods on a session are query, insert, and flush.
The preferred way to use a session is the with statement:
s = Session(some_db)
with s:
s.insert(some_obj)
obj = s.query(SomeClass).one()
...
The with statement ensures that end_request is called on the connection which can have a significant performance impact in some situations because it will allow other threads to make use of the socket connecting to the database.
The session also responsible for ordering operations and knowing when operations need to be flushed, although it does not currently do anything intelligent for ordering.
Create a session connecting to database.
| Parameters: |
|
|---|
connect is a thin wrapper around __init__ which creates the database connection that the session will use.
| Parameters: |
|
|---|
End the session. Flush all pending operations and ending the pymongo request
Insert an item into the queue and flushes. Later this function should be smart and delay insertion until the _id field is actually accessed
Update an item in the database. Uses the on_update keyword to each field to decide which operations to do, or.
| Parameters: |
|
|---|
Warning
This operation is experimental and not fully tested, although it does have code coverage.
See also
Query class
Get the results of query. This method will flush the queue
Begin a remove query on the database’s collection for type.
See also
RemoveQuery class
Remove a particular object from the database. If the object has no mongo ID set, the method just returns. If this is a partial document without the mongo ID field retrieved a FieldNotRetrieved will be raised
| Parameters: |
|
|---|
Execute a remove expression. Should generally only be called implicitly.
Execute an update expression. Should generally only be called implicitly.
Get the index information for the collection associated with cls. Index information is returned in the same format as pymongo.
Clear the queue of database operations without executing any of the pending operations
Clear all objects from the collections associated with the objects in *cls. use with caution!
Perform all database operations currently in the queue


Track characters Select characters in the list to highlight scenes where they appear. CMD + click to select multiple. Selecting more than one name will highlight scenes where ALL characters are present.

And (remember) when We took a covenant from the Children of Israel, (saying): Worship none but Allah (Alone) and be dutiful and good to parents, and to kindred, and to orphans and Al- Masakin (the poor), and speak good to people [i.e. enjoin righteousness and forbid evil, and say the truth about Muhammad Peace be upon him ], and perform As-Salat (Iqamat-as-Salat), and give Zakat. Then you slid back, except a few of you, while you are backsliders. |

And when We made a covenant with the Children of Israel. You shall serve none but Allah. And do good to (your) parents, and to the near of kin and to orphans and the needy, and speak good (words) to (all) men, and keep up prayer and pay the poor-rate.

And (remember) when We made a covenant with the Children of Israel, (saying): Worship none save Allah (only), and be good to parents and to kindred and to orphans and the needy, and speak kindly to mankind; and establish worship and pay the poor-due. Then, after that, ye slid back, save a few of you, being averse. |

We made a covenant with the Children of Israel: "You shall not worship except GOD. You shall honor your parents and regard the relatives, the orphans, and the poor.

| 002:083 Sarwar | : |
We made a covenant with the children of Israel that they should not worship anyone except Me, that they should serve their parents, relatives, orphans, and the destitute, that they should speak righteous words to people, and that they should be steadfast in their prayers and pay the religious tax. But soon after you made this covenant, all but a few of you broke it heedlessly. |

And when We made a covenant with the children of Israel: You shall not serve any but Allah and (you shall do) good to (your) parents, and to the near of kin and to the orphans and the needy, and you shall speak to men good words and keep up prayer and pay the poor-rate.

And remember the time when WE took a covenant from the Children of Israel: 'You shall worship none but ALLAH and be kind to parents and to the kindred and orphans and the poor, and speak to men kindly and observe prayer, and pay the Zakat.' then you turned away in aversion, except a few of you. |

And remember We took a covenant from the Children of Israel (to this effect): Worship none but Allah; treat with kindness your parents and kindred, and orphans and those in need; speak fair to the people; be steadfast in prayer; and practise regular charity.

When I first tried to remote into my work machine, man that thing was slow. My good pal helped me figure out a set of command line options to make it usable. The main things to do were to set the command line option to have rdesktop compress the data, and to minimize the themes on my Windows machine. Now I feel like the remote experience is faster on my Ubuntu machine than it was from my Windows machines... ofcourse my Windows machines had much slower hardware.

Popcorn Time software was a multi-platform, open source BitTorrent client which included an integrated media player. The program and its forks of the same name are free alternatives to subscription-based video streaming services (such as Netflix). Popcorn Time used sequential downloading to play copies of films listed by the website yts.to (earlier yify-torrents.com & yts.re), also known as YIFY (although other trackers can be added and used manually).

So I've been learning to play the guitar for around 3 months now.
It's coming along well :)
I figured I'd plug Tuxguitar and a few sites/apps I've been using.
Windows users might know of Guitar Pro which is a software that allows creation of tabs and plays them back.
However what most users dont know is that a free (gratis) and open source equivalent called tuxguitar exists.
This will be very helpful when viewing the *.gp3, *.gp4 and other files that are available on various guitar tab sites.
(Or view those rumoured hundreds of thousands of tabs I'd heard are available on some peer2peer technologies ;) )
It is written in Java and is thus available on Windows, Linux, Solaris or any architecture with a JVM. Tuxguitar in the Ubuntu 8.04 repository has known sound issues on AMD64.. so you better get the latest version directly from the site.
Also very useful to practice your strumming is GTick (On ubuntu simple apt-get install gtick). One good page to learn strumming is here.
Happy guitaring.

I wish I could tell you more about whatever it is you have to show me. But it doesn't look like you have anything to show.

Displays the lifecycle of the requests in ServiceWorker and how they are managed. Whether the installation is completed or not and if the requests are being handled by the service worker. Additional knowledge about the interface can be useful.


As you can see, the main window provides many of the common operations. You can jump to any question either by typing its number or by dragging a slider, or process questions one at a time using the Next/Previous buttons.
But wait, there's more! The File menu lets you XXX
The Edit menu lets you XXX
And the View menu lets you see the Statistics...
We particularly like the Statistics report, which shows not only how many A, B, C and D answers there are, but also how many incomplete questions, questions with no answer, and questions with no Chapter Objective. This can be helpful in assessing new exams from authors, as well as for monitoring ongoing changes.
The version being shown here is a prototype, and lacks some important features. That does not mean it is a toy - it is a full-scale program developed using object-oriented programming models and techniques.
The limitations? First, the questions and answers have as yet no format capability, to allow keywords in bold, computer input in Courier, or whatever. Many of the editing capabilities (such as Find, and Cut/Copy/Paste) do not function yet in this version. But you can see - from the shaded menu items - the functionality that is planned.
As well, during the later stages of development, we can work with the publications team to add or change functionality.
TestEdit can directly print a draft of the exam. This will not get mixed up with what we send the students, because it is clearly marked as being a draft. It shows the exam and the correct answers, and is an ideal format for proofing by authors, TEs, and others.
TestEdit can save in its own format (see below). But it can also export a file to the web, so that you can run the questions interactively for Intranet/Internet delivery. The present version, already being used in some courses to provide review questions that the students can answer after each chapter, generates simple but adequate HTML. A later version will be component-based for better delivery with no cheating. The program can [soon] also generate Microsoft Rich Text Format documents that MS Word can open directly. And, it is planned to add the ability to generate a Sylvan Prometric file, so that exams can be sent directly to Sylvan without any further manual processing (this capability depends on obtaining the proprietary file format that they use). Because TestEdit is object-oriented, it is fairly easy to add new file formats.
Now you no longer need to worry about authors who work on different computing platforms than your central publications department. TestEdit is totally portable to any modern computing platform. While the standard version is a native MS-Windows 95/98/NT binary, the included Java binary can be run on MS-Windows, Macintosh, Solaris, Linux, OpenBSD, Novell, or any other Java-enabled computing platform. The software installs easily using standard installation tools (InstallShield on MS-Windows and InstallAnywhere on Java).
The program's native file format is not RTF, nor a proprietary binary file like an MS-Word document, but a` structured text file format. Authors who prefer to work in existing tools can prepare input using vi, emacs, perl, WordPerfect (save as Text), or any other edtior of their choice, and need only validate using TestEdit before sending the files to your publications department.
TestEdit is the answer to all your examination editing problems. Buy it now! Contact Ian Darwin at Darwin Open Systems, http://www.darwinsys.com/.
