magento2 – Cart rules and coupon compatibility

I need to implement multiple cart rules, in particular coupon codes with compatibility rules, and was wondering if exists an extension that already does this.

I’ll make you an example, let’s say I got 6 types of coupons:

coupon type 1 = CT1

coupon type 2 = CT2

coupon type 3 = CT3

coupon type 4 = CT4

coupon type 5 number1 = CT5-1

coupon type 5 number2 = CT5-2

coupon type 5 number3 = CT5-3

They are all applicable on the entire cart total, but you can’t use coupons of type 1 multiple times AND you can’t add another coupon of type 2, but you can of other types. A quick scheme:

          CT1     CT2     CT3**   CT4**   CT5-1     CT5-2     CT5-3

CT1        ---     X       O       O        X         X         X

CT2         X     ---      O       O        O         O         O

CT3**       O      X      ---      O        O         O         O

CT4**       O      O       O      ---       O         O         O

CT5-1       X      O       O       O       ---        X         X

CT5-2       X      O       O       O        X        ---        X

CT5-3       X      O       O       O        X         X        ---

X means you can’t use with that coupon type

O means you can stack them

The ones with ** you can use multiple of same type

I hope I explained it well.

compatibility – Get app’s compatibilty matrix from Play Store

I am trying to figure out why Play Store claims that an app is incompatible with my device. Sideloading the app works fine, I’d just like to get it over the Play Store so that I don’t have to update manually.

I know that, as a developer, you can set criteria on what devices are compatible to your app.

Is there any way to get those criteria as a customer?

accessories – Hardware requirements for HomeKit compatibility?

I bought some wifi enabled color changing “smart” lights that work with the Google Home app and Amazon Alexa but not with Apple HomeKit. As someone who’s heavily invested in the Apple ecosystem, this came as a disappointment and it made me wonder if it’s possible for manufacturers to make their devices compatible simply by pushing a firmware update or if there are specific hardware requirements that have to be met.

internet explorer – Will implementing HSTS cause parts of my website which use IE6 compatibility mode to break?

I am converting a legacy system designed for IE6 to work on modern browsers.

Those parts of the site which have not yet been converted, will only work on Internet Explorer, and the IE6 emulation is provided via the following tag.

<meta http-equiv="X-UA-Compatible" content="IE=5">

I am planning on adding HSTS to the site (via CloudFlare).
I see that HSTS is supported only for Internet Explorer 11 and higher.

Will adding HSTS cause those parts of my site which rely on IE6 emulation to break?

compatibility – Older Nikon body won’t work with AF-P lens

AF-P lenses are a newer Nikon technology that doesn’t work with older Nikon bodies, such as your D50. There is no way to adjust any settings or update firmware to make your camera any more compatible with this lens.

From Nikon’s product page for the lens:

The number of cameras compatible with both lenses is limited. Even for compatible cameras, firmware update may be required

Fully compatible models: D7500, D5600, D5500, D5300*, D3400, D3300*, D500 and later models

Compatible models with limited functions: D5, D810 series, Df, D750, D7200, D7100, D5200, Nikon 1 series with the FT1

Incompatible models: D4 series, D3 series, D2 series, D1 series, D800 series, D700, D610, D600, D300 series, D200, D100, D7000, D5100, D5000, D90, D80, D70 series, D3200, D3100, D3000, D60, D50, D40 series, film cameras

microsoft surface – USB-C display compatibility

I’m searching for a monitor to connect it to my Surface Book 3 15″. And I want to use only the USB-C cabele (also use to load my laptop). The Surface Book offers USB 3.x Gen 2 @ 10Gb/s DP alt mode with DisplayPort 1.4 bandwidth (HBR3 + DSC)

Does it work with a monitor that supports DP 1.2 and 1.4 but without HBR3 support?

Or will it work with a monitor that has a thunderbolt connector. Can I connect the 3.x Gen 2 to Thunderbolt – is Thunderbolt “downward compatible”?

drivers – Linux compatibility with HP DeskJet All-in-One Ink Advantage Printers

My old printer was HP DeskJet 2135 All-in-One Ink Advantage Colour Printer which worked very well with several versions of Linux and HPLIP 3.16.3

Now I need to buy a new printer which I wish is of similar class.

I am thinking of : HP DeskJet 2335 All-in-One Ink Advantage Colour Printer OR
HP DeskJet 2778 All-in-One Ink Advantage Wireless Colour Printer

Can any one tell me about the compatibility of these two printers (especially the first one ‘2335’) with Linux.

On the following website : what is mentioned is a bit confusing.

I am not sure what does the term “HP DeskJet Ink Advantage 2300 All-in-One” means. Does it includes all printer in that series that start with 23XX, which should include HP DeskJet 2335 All-in-One Ink Advantage Colour Printer also ?

ap.analysis of pdes – Compatibility condition for the global well-posedness of coupled Stokes equations

Consider the following coupled Stokes-Darcy systems in a simplified domain $Omega=(-1,1)times(-1,1)$, WLOG, we may assume the horizontal variable to be periodic. The Stokes flow occuplied the upper part $Omega_{c}=(-1,1)times(0,1)$, and the lower part is Darcy flow $Omega_{m}=(-1,1)times(-1,0)$, clearly $Omega=Omega_{c}cupOmega_{m}$. The two fluid contact on the interface $Gamma=Omega_{c}capOmega_{m}=(-1,1)times{0}$. We name the top and bottom of $Omega$ to be $Gamma_{c}$ and $Gamma_{m}$.

partial_{t}u_{c}-nablacdotmathbb{T}(u_{c},p_{c}) & =f, & text{in} Omega_{c}, \
nablacdot u_{c} & =0, & text{in} Omega_{c}, \
u_{m} & =-nabla p_{m}, & text{in} Omega_{m}, \
nablacdot u_{m} & =0, & text{in} Omega_{m}, \
u_{c}cdot n & =u_{m}cdot n, & text{on} Gamma, \
taucdotmathbb{T}(u_{c},p_{c})n & =-alpha u_{c}cdottau, & text{on} Gamma, \
ncdotmathbb{T}(u_{c},p_{c})n & =-p_{m}, & text{on} Gamma, \
u_{c} & =0, & text{on} Gamma_{c}, \
partial_{x_{2}}p_{m} & =0, & text{on} Gamma_{m},

where $mathbb{T}(u,p)=frac{1}{text{Re}}(nabla u+nabla u^{T})-pmathbb{I}$, $alpha>0$ is a constant.

Question: What are the compatibility conditions satisfying by the initial Stokes velocity $u_{c}|_{t=0}=u_{0}$ to ensure the global existence of classical solution to this system?
