Car sales plunge 56% in October
by Our CorrespondentKARACHI: The condition of the automobile sector continued to worsen in Pakistan as car sales plunged 56% on a year-on-year basis, posting the largest decline since March 2009 mainly due to high prices following massive rupee depreciation and higher interest rates for auto financing.
According to data released by the Pakistan Automotive Manufacturers Association (Pama), auto sales were recorded at 10,853 units in October 2019 compared to 24,850 units in the same month of the previous year.
“The decline is primarily attributable to the recent government drive to document the economy, higher automobile prices post-rupee devaluation, higher interest rates for auto financing and overall economic slowdown,” said Topline Securities’ analyst Hammad Akram.
The situation remained dismal for all the three major market players as they posted a significant year-on-year decline in sales.
Honda Atlas Cars remained the major laggard with a 72% year-on-year drop in sales to 1,384 units in October 2019, its highest monthly decline in 7.5 years.
“Sales of City and Civic variants fell 77% year-on-year amid a significant increase in their prices while BR-V sales declined 33%,” the analyst said.
Indus Motor Company fared no better and recorded a drop of 61% in sales to 2,496 units in October 2019.
Sales of Pak Suzuki Motor Company were down 48% year-on-year to 6,973 units, posting the largest decline in over seven years.
“The decline in sales was led by Wagon-R and Cultus, whose sales were down 84% and 51% respectively, due to a recent shift in customer interest towards Alto and newly launched Picanto by Kia-Lucky Motors,” the analyst added.
In the first four months of the current fiscal year, auto sales fell 46% to 45,161 units against 83,201 units in the same period of the previous fiscal year.
On a month-on-month basis, Indus Motor surprisingly reported an increase of 18% in volumetric sales.
“This is mainly due to 10% and 86% month-on-month increase in Corolla and Hilux sales respectively,” Akram said. “We believe this has occurred due to different waiver schemes offered by the company in collaboration with commercial banks.”
On the other hand, Pak Suzuki Motor faced the largest month-on-month decline in car sales of 15%, followed by Honda Atlas, which reported a fall of 4% in sales.

Goods stuck at Chattogram port as truckers, covered-van owners go on strike
by bdnews24.comThe transportation of goods and containers to and from the Chattogram port have come to a halt amid the ongoing strike by some sections of transport workers over the new road traffic law.
Not a single truck or covered van entered the port on Wednesday morning even as authorities continued loading and unloading goods.
Transport owners and workers went on strike in protest against harsher punishments for traffic offences under the new law.
Stakeholders fear the transport strike could have serious implications for the export business if it continues for a few more days.
Rows of trucks and covered-vans were parked on the Airport Road near the Chattogram port on Wednesday.
“The number of containers waiting to be delivered will rise if the strike continues. We already have 35,000 containers at the port whereas our capacity is 49,000 containers. Usually, around 4,000 containers are delivered every day from the port.”
Container transportation from the nearby depots has also stopped due to the strike.
The effects of the strike could extend to imports and devastate business at the port, said C&F Agent Association President AKM Akhter Hossain. It could also hamper manufacturing industries if the delivery of raw materials is held up, he said.
The Chattogram port plays an important role in the country's economy as it is the principal gateway for import and export goods.

Exported Types
The RxPlayer being written in TypeScript, it has type definitions attached to its source code that can be helpful if you develop an application in TypeScript yourself.
“Using” types
Because we follow the usual way of adding definition files (as d.ts
file
alongside our sources), those typings should be auto-exported when importing our
library in your favorite editor (as long as it is linked to a TSServer of some
sort).
Importing specific types
As some APIs can have pretty complicated arguments, you might also want to import some of our internal type definitions into your code.
To simplify this process, we export some type definitions which can be imported through the following line in your file:
import { SOME_TYPE } from "rx-player/types"
Here are the list of exported types, per category.
RxPlayer Constructor
The type IConstructorOptions
corresponds to the interface that the
RxPlayer constructor accepts as an argument.
Example:
import RxPlayer from "rx-player";
import { IConstructorOptions } from "rx-player/types";
function generateConstructorOptions() : IConstructorOptions {
const videoElement = document.querySelector("video");
return {
stopAtEnd: false,
videoElement,
};
}
const options = generateConstructorOptions();
const player = new RxPlayer(options);
export default player;
Two constructor options have also their type definition exported, those are:
-
IAudioTrackPreference
: which is the type of a single element in thepreferredAudioTracks
array. -
ITextTrackPreference
: which is the type of a single element in thepreferredTextTracks
array.
loadVideo
The ILoadVideoOptions
type corresponds to the argument to give to the
RxPlayer’s method loadVideo
.
Example:
// the type(s) wanted
import { ILoadVideoOptions } from "rx-player/types";
// hypothetical file exporting an RxPlayer instance
import rxPlayer from "./player";
// hypothetical file exporting a configuration object
import config from "./config"; // define a global config
function generateLoadVideoOptions(url : string) : ILoadVideoOptions {
return {
url,
transport: "dash",
autoPlay: true,
};
}
const loadVideoOpts = generateLoadVideoOptions(config.DEFAULT_URL);
rxPlayer.loadVideo(loadVideoOpts);
Speaking of loadVideo
, some subparts of ILoadVideoOptions
are also
exported:
-
ITransportOptions
: type for thetransportOptions
property optionally given toloadVideo
. -
IKeySystemOption
: type for an element of thekeySystems
array, which is an optional property given toloadVideo
.To clarify, the
keySystems
property in aloadVideo
call is an optional array of one or multipleIKeySystemOption
. -
ISupplementaryTextTrackOption
: type for an element of thesupplementaryTextTracks
array, which is an optional property given toloadVideo
. -
ISupplementaryImageTrackOption
: type for an element of thesupplementaryImageTracks
array, which is an optional property given toloadVideo
. -
IDefaultAudioTrackOption
: type for thedefaultAudioTrack
property optionally given toloadVideo
. -
IDefaultTextTrackOption
: type for thedefaultAudioTrack
property optionally given toloadVideo
. -
INetworkConfigOption
: type for thenetworkConfig
property optionally given toloadVideo
. -
IStartAtOption
: type for thestartAt
property optionally given toloadVideo
.

corresponds to both the type returned by the getAudioTrack
method and emitted as the payload of the audioTrackChange
event.
Example:

return rxPlayer.getVideoTrack();
}
streamEvent / streamEventSkip events
The type IStreamEvent
corresponds to the payload of either a streamEvent
or
a streamEventSkip
event.
The type IStreamEventData
is the type of its data
property.

import { IStreamEvent, IStreamEventData } from "rx-player/types";
// hypothetical file exporting an RxPlayer instance
import rxPlayer from "./player";
function processEventData(eventData : IStreamEventData) {
if (eventData.type === "dash-event-stream") {
console.log("DASH EventStream's event received!");
}
}
rxPlayer.addEventListener("streamEvent", (evt : IStreamEvent) {
processEventData(evt.data);
});

VONDA7 - Against The Clock
by Natalia PanzerVONDA7 – Against The Clock
Against The Clock is a series where we give an artist 10 minutes in the studio and see what they come up with.
Since leaving her hometown of Poznań, Polish producer VONDA7 has been immersing herself in genres such as French house, garage and disco in the club-rich cities of Amsterdam and London.
She currently lives in Berlin where she runs the imprint art | werk, a platform that aims to showcase left-wing techno, alternative pop, visual arts and everything in between.
So far this year, she’s self-released three albums via art | werk, the most recent being the collaborative TEAMWORX vol.1 made with NRVVS, Elisa Bee and Raito.
Watch as she builds a hefty “nice and funky” techno track and then follow her suggestion and check out her recent remix of Nocturnal Sunshine’s ‘U&Me’.

Read guidance
Agents and individuals can learn about Self Assessment via software by reading guidance pages on GOV.UK.
For agents:
- Self Assessment for Agents: HMRC online services
- Self Assessment commercial software suppliers
- Use software to help complete your client’s Self Assessment tax return
For individuals:
- Self Assessment (index page)
- Self Assessment tax returns
- Register for and file your Self Assessment tax return
- Self Assessment commercial software suppliers
- Use software to help complete your Self Assessment tax return
We encourage you to include links to the relevant guidance in your software.
Register for Self Assessment for Agents
Agents must register for, or already be registered for, Self Assessment for Agents before they can use this service. This is also known as getting an agent code - HMRC allocates the agent a Self Assessment agent code, in the format A12345.
More details are given at Self Assessment for Agents: HMRC online services. We encourage you to include this link in your software.
Create an HMRC online services for agents account
Agents must create, or already have, an HMRC online services for agents account before they can use the service. This also gives them access to other services for agents.
They must also enrol this account for Self Assessment for Agents, which links it to their Self Assessment agent code.
They do this on GOV.UK at HMRC services: sign in or register. We encourage you to include this link in your software.
Create an HMRC online account
Individuals must create, or already have, an HMRC online account before they can use the service. This also gives them access to their Personal Tax Account.
They do this on GOV.UK at HMRC services: sign in or register. We encourage you to include this link in your software.
Register for Self Assessment
Individuals must register for, or already be registered for, Self Assessment before they can use this service. Once registered they get a Self Assessment Unique Taxpayer Reference (UTR).
Agents’ clients must also register for Self Assessment themselves - the agent cannot do it for them.
They do this on GOV.UK via their Personal Tax Account, which they access at HMRC services: sign in or register. We encourage you to include this link in your software.
Authorise agent
Agents must obtain authorisation from their clients to act on their behalf before they can use this service, for example using form 64-8.
They do this on GOV.UK at Agent authorisation to deal with HMRC. We encourage you to include this link in your software.
Choose software
We provide a list of Self Assessment software applications so agents and individuals can choose the right software for their needs.
Link software to HMRC
Agents and individuals using your software to connect to the Self Assessment APIs must grant authority to your software to interact with HMRC on their behalf.
Because the APIs to help complete a return and the API to submit a return use different technology, the linking process is different for each.
Help complete a Self Assessment return
We use the open standard OAuth 2.0. This involves the agent or individual signing in to their HMRC online account and following our grant authority user journey.
We then generate an access token for the user, which the software must include in subsequent API requests.
For more details see Authorisation - user restricted endpoints.
Submit a Self Assessment return
The agent or individual enters their HMRC online account user ID and password directly into their software.
The software must pass them in subsequent API requests as explained in Transaction Engine: Document Submission Protocol.
Get data from HMRC to help complete Self Assessment return
The individual or agent’s software can get data from HMRC to help complete some parts of the tax return.
The software does this by calling one or more of the following APIs:
- Individual PAYE API - recommended for PAYE data, but is currently in private beta and will eventually replace the following four Individual APIs
- Individual Benefits API
- Individual Employment API
- Individual Income API
- Individual Tax API
- National Insurance API
- Marriage Allowance API
Each API returns either the requested data or an appropriate error response. The most common errors are:
- no data found for the given individual and tax year
- end user not authorised for the given individual, for example an agent without client authorisation
For more details see the above API documentation.
To use these APIs, your application must comply with our terms of use. You must accept the terms of use before we issue your application’s production credentials.
Complete and submit Self Assessment return
Once they have completed the Self Assessment return in their software, the individual or agent submits it to us online. To do this, their software uses the following API:
Get help and support
Individuals and agents can get help and support via the following channels:
- you as their software supplier
- the “Get help with this page” link on relevant pages in the grant authority journey - for help with signing in, 2-step verification, identity checks and granting authority
- the HMRC Online Services Helpdesk - for help with technical queries that the software supplier can’t resolve
- the HMRC Income Tax Helpline - for individuals querying the data received from HMRC
- the HMRC Agent Dedicated Line - for agents querying the data received from HMRC

“Design will save the world.” That’s why we became designers — the yearning for having a positive impact, shaping our surroundings, and designing a better tomorrow. It’s a knack we have: to think about the future and how to get there. Lately, we lost focus.
Design has been misused as a tool for manipulation, trickery, and freedom wearing. Facebook, Google, and most of the tech industry easily fall under this umbrella. Dark patterns: “a user interface that has been carefully crafted to trick users into doing things, such as buying insurance with their purchase or signing up for recurring bills” 1 became so ubiquitous that they’re used without consideration of their impact. How many apps did you use today which have an infinite scroll? How many notifications did you receive this morning and how many were needed?
That’s where ethics is finding its place in design. “Ethics doesn’t distinguish between right or wrong. Rather, it guides people to a preferable future, universally.”2. It becomes the constant questioning and alignment of intention; the reminder that what we create has an impact. Every decision we make, whether we intend it or not, affects those we’re designing for. Take the example of the infinite scroll: it makes people spend more time in your app - but at the expense of what? Perhaps sleep deprivation and social exclusion.
It doesn’t need to be that way: a lot of companies, designers, and developers are laudably proving that every day. And it’s not just about ethics — its good business:
Apple
Privacy as the main competitive advantage. It’s in every product, their advertising, and website: Apple’s new business model is not subscriptions, it’s privacy. Why? It’s good for people, and it’s one of the most challenging things for their competitors to copy as it would mean a complete change of business models.
Are.na
Transparency from the ground up. If you haven’t heard of are.na please go check them out! Fast Company said about are.na that “In the groundswell of anger and suspicion toward social media platforms, Are.na feels like a necessary antidote.”3 Their open and transparent ways of doing are indeed a breath of fresh air - see their transparent roadmap here.
DuckDuckGo
Google without the evil. Also, another proof that you can run a successful tech company while doing things the right way. Gabriel Weinberg, DuckDuckGo founder, said: “Our vision is to set a new standard of trust online. The Internet shouldn’t feel so creepy and getting the privacy you deserve online should be as simple as closing the blinds.”. Read more about their business model here.
Monzo
A new type of bank. With their transparency page, Monzo is showing the way on how to build trust, and be accountable for their actions. See more here.
Everything interconnects:
These examples show us that it’s possible. Now let’s get started! As designers, we were taught to design with people at heart. We should remember that. However, we shouldn’t forget that people have a place in society, the environment, and business. Embrace complexity. We can’t design in the vacuum.
To help us do that, we’ve started developing a new design critique tool. It helps us be mindful about the potential impact and to ideate around possible solutions to the challenges we identify. Here’s a snapshot of the framework:
Start by gathering the team to talk impact. Take a project you’re working on, have worked, or are about to start. Give a short explainer on what problems you’re trying to solve and how you’re answering them. Then map those solutions to their impact in each one of the verticals in the template. Ask yourself: what are the things you designed that can impact people, the environment, society, and business in a positive way? And negatively?
Take the example of a transportation service (like Uber or Lift). Your system might look something like:
People:
Positive impact: convenient and quick access to a ride for users and a new income source for drivers.
Negative impact: unregulated work, might lead to insecurity in rides, and loss of worker’s rights.Business:
Positive impact: working as a transportation platform with a clear use-case, for users and workers, allows for an easily scalable solution.
Society:
Negative impact: More congested roads, slower traffic, and more city space taken from people.
Environment:
Negative impact: the business incentive is to put more cars on the streets to enable quick access, causing more noise and pollution in our cities.
When you’re done, you should have a clearer picture of the impact your design is having. Is there anything you can add, change, or remove, to make the overall system more positive? To balance the disparities?
Think of it as an always-evolving picture. Have it nearby, make sure to update it, and don’t stop questioning how to make the system better.
What next?
We know this won’t be the solution to all problems. However, we believe that being mindful of our decisions is a good place to start.
If you found value on this, tried this tool, have questions, suggestions, or want to share how you’re tackling these issues – please let us know!

MICHAEL COLLINS 1996 A film review by Timothy Voon Copyright 1997 Timothy Voon
Cast: Liam Neeson, Aidan Quinn, Julia Roberts, Alan Rickman, Stephen Rea, Ian Hart, Brendan Gleeson, Stuart Graham, Charles Dance Director: Neil Jordan Screenplay: Neil Jordan
'An eye for an eye', and a dead cabinet minister for every year under British Rule. That would mean 800 years, and a lot of dead ministers. Not a good idea, but when desperation becomes despair, people will do anything to succeed. I say 'turn the other cheek', but that's Tim Voon speaking, not Michael Collins.
So the year is around 1915, and the republic of Ireland is having problems establishing their independence. In the midst of this unsettled times, rises a man by the name 'Michael Collins' who has a single, focused vision for his nation - freedom! Rough around the edges, gritty and plain spoken, this working class man, who in another time and place could have been an ordinary husband, father and brother; employs guerrilla tactics, to achieve his end. His philosophy summarised would be, 'when no one listens, act.' Which in no uncertain terms means assassinations and explosions, with the occasional innocent sacrificed for the cause.
Liam Neeson, Scottish? Irish? English? Plays Collins down to a very fine line of detailed particulars - of note is the Irish accent, which Aidan Quinn and Julia Roberts have some difficulty mastering (they are after all American). The director has captured the beauty of Ireland at its grim best. Heavy, dark grey clouds, threatening to unleash its heavy burden upon cold, colourless, slate roof tops and soot filled chimneys, puffing smog upwards to the already overcast sky. Cobbled streets, filled with the hustle, bustle, day to day mundane, chore-laden pedestrian darting through and fro, avoiding the clip-clapper of horses pounding their hooves on lifeless stone roads. Add to this the rit-rattle of ricocheting bullets, tall smoking buildings, and distant screams and you have for yourself a city in distress.
The result of these extreme measures, is history itself. The establishment of the independent self-ruling state of Ireland. Not independence, but neither is Australia (an ex-penal colony). The treaty with the British, resulted in disunity and disharmony amongst the IRA, with a resulting split; but Collins the soldier, a product of years of resentment of English rule, knows when to stop fighting and regain his humanity - to once again become Collins the working man.
This is not a particularly uplifting movie by any accounts, but it does tell a story of an ordinary man forced to make difficult decisions under very tense circumstances. Whether the details of the plot are accurate, I do not know; but if in doubt, all you have to do is open the pages of a British history book to find the name 'Michael Collins' included within.
Comment: I say, passive resistance on this occasion for added variation.
Revolutionary Feel Scale: 0% Hitler \ *MICHAEL COLLINS* \ Gandhi 100%

A Shimmering Air Jordan 11 Is Dropping Just in Time for Your Holiday Parties
A women’s exclusive however.
by Robert Marshall Jr.Just in time for your holiday parties and New Year celebrations, Jordan Brand is less than a week away from dropping the shimmering Air Jordan 11 “Vast Grey/Silver.”
The women’s exclusive sneaker features a glittery looping mudguard, rather than the shinny patent leather version we’re use to seeing on the AJ11. Its theme is a nod to one of Michael Jordan‘s initial thoughts when he first saw Tinker Hatfield’s prototype of this iconic shoe; he imagined grooms and brides, ball-goers, young prom dates and the like sporting the statement sneaker on their feet.
What’s more is that this sneaker features a white base, a cloudy translucent outsole, and an exposed metallic Jumpman at the ankle.
The Air Jordan 11 “Vast Grey/Silver” will hit retailers, like Nike.com, on November 30 for $220 USD.
In other AJ11 news, Nike SB is dropping a Dunk High inspired by the Space Jam iteration.
Air Jordan 11 “Vast Grey/Silver”
Release Date
November 30, 2019 - 10:00 am EST (TBC)

Pre-Defined Functions
on Synthetic Biological Components
add(element)
The add() function appends the specified element to the list of a component's elements.
Examples:
// add the Strength Property to the Promoter Part Type
Property Strength(num);
Promoter.add(Strength);
// add the Promoter Part Type to the hybridDevice hybridDevice.add(Promoter);
get(idx)
The get() function has one parameter that specifies the position of the element which should be returned. The indexing of the elements starts with the index 0.
Examples:
// get the first element of the abstractDevice, i.e., Promoter
abstractDevice.get(0);
// get the i-th element (i.e., the 4th) of the arrayDevices
num i = 3;
arrayDevices.get(i);
remove(idx)
The remove() function takes on parameter which specifies to index of the element that should be deleted from the list of elements.
Examples:
// delete the first element of the abstractDevice (i.e. the Promoter)
abstractDevice.remove(0);
// delete the second Property of the Promoter Part Type (i.e., RelativeStrength)
Promoter.remove(1);
size()
The size() function returns the size of the component. The returned value can be assigned or compared to a variable.
Examples:
// the following statement returns 4
abstractDevice.size();
// assign the size of the arrayDevices array to the nSize variable
num nSize = arrayDevices.size();
toSequence()
The toSequence() function returns a txt value that represents the DNA sequence of the biological component. If the toSequence() function is utilized on a device instance, the function returns the DNA sequence of the assembled Device. For abstract and hybrid devices, the toSequence() function inserts placeholders for the Part Types.
Example:
// print the sequence of the concreteDevice to the console
print("DNA sequence of the concreteDevice:", concreteDevice.toSequence());
// assign the sequence of the hybridDevice to the sequence txt variable
txt sequence = hybridDevice.toSequence();


Cannot connect to this slave (hot_standby = off in postgresql.conf)
Should see two entries for streaming slaves when checking from master now
After a few minutes, should start seeing archived WAL files cleaned up automatically
Check logs
Replays WAL archives first using restore_command
Connects to primary for streaming replication
Sees it’s streaming replication, so omnipitr-restore -sr option allows restore_command to exit cleanly despite throwing an error that it can't find the next WAL file. Otherwise would be stuck in loop until restore_command successfully replayed a WAL file.
Non-streaming Replication
Comment out “primary_conninfo” line from omnislave recovery.conf
Remove “-sr” flag from restore_command
Restart slave (as postgres user)
/usr/pgsql-9.3/bin/pg_ctl restart -m fast -D /var/lib/pgsql/9.3/omnislave/
archive_timeout of master determines how far behind slave could possibly be
--recovery-delay (-w) option to omnipitr-restore can force slave to lag behind a specified period of time
Recovery slave to quickly undo mistakes
Only method of replication pre 9.0
UNDO ABOVE CHANGES
Restart slave again and ensure it connected to primary
/usr/pgsql-9.3/bin/pg_ctl stop -m fast -D /home/training/mydb
Restore - File System
As postgres system user, create a new data directory
mkdir /var/lib/pgsql/9.3/omnirestore

Upgrading
Dump/Restore
Works on all versions
Use the pg_dump binary of the upgrade target
8.4+ has parallel pg_restore
9.3+ has parallel pg_dump
Same caveats mentioned previously (smaller dump/longer restore)
pg_upgrade
In-place upgrade of data files
Works only for 8.4.7+ (all previous versions must dump/restore)
OS w/ hard link support can greatly decrease upgrade time
Ex: 700GB upgrade in under 5 minutes
Failover
Will be failing over to the first slave we made (/var/lib/pgsql/9.3/slave/)
Ensure failover slave has same archive_command set as the original master but with appropriate path settings (would typically be the same if on different servers).
